Gangliogliomas represent approximately 0.2% of all the intracranial tumors. Ganglioglioma arising from the cerebellum is rare, with a rate of 1.5-9% of CNS gangliogliomas. The authors report a case of cerebellar ganglioglioma with a huge cyst. A 28-year-old man presented headache and ataxia. Computerized tomography (CT) demonstrated a huge cyst at the vermian region with calcification located at the peripheral side of the cyst. Magnetic resonance imaging (MRI) with administration of Gd-DTPA showed a slightly enhanced small mass at the left side of the cyst. Preoperative diagnosis of the lesion seemed to be a cystic astrocytoma. The tumor was removed subtotally through the midline suboccipital approach. Pathological examination of the tumor specimen revealed a ganglioglioma. The postoperative course was uneventful with no sign of tumor regrowth on repeated MRI. According to the previous 17 reports of cerebellar ganglioglioma including our case, the shorter interval from onset to the diagnosis and clinical symptoms such as increased intracranial pressure were conspicuous as compared with supratentorial ganglioglioma because of the anatomically narrow space of the posterior fossa. Neuroradiological findings showed tumor enhancement in 86% of the cases, calcification in 67%, and cyst formation in 53%.

The authors report on a patient with postoperative CSF (cerebrospinal fluid) leakage subsequent to transsphenoidal surgery where cisterno SPECT (single photon emission computed tomography) demonstrated the precise location of a CSF fistula. Seven months after surgery, the patient suffered from CSF rhinorrhea and headache. MRI (Magnetic Resonance Imaging) revealed significant contrast on T1-weighted images resulting from measurements in the right sphenoid sinus, which were hyperintense relative to CSF. On the basis of signal intensity differences, MRI could not distinguish between CSF leakage and postoperative scarring. Therefore, we performed cisterno SPECT at the same time as RI cisternography with intrathecal lumbar injection of 111In-DTPA which revealed dramatic accumulation of the tracer in the right sphenoid sinus. The patient underwent re-operation via a transsphenoidal approach, and the CSF leakage was repaired using fat-in-fibrin glue and the sella floor was reconstructed by hydroxyapatite platinge. These results suggest that cisterno SPECT may be useful in identifying the precise location of CSF fistulae, while other techniques fail to show evidence of CSF leakage.

We report a case of refractory tuberculous meningitis which was markedly improved by intrathecal administration of isoniazid (INH). The patient was a 35-year-old woman diagnosed with systemic lupus erythematosus (SLE) at age 25, who was being managed with steroid therapy. She was admitted to another hospital due to miliary tuberculosis at age 34, and after discharge continued with a regimen of 2 anti-tuberculosis drugs (INH. Rifampicin (RFP)). She was admitted to our hospital with severe headache and fever on June 18, 2001. She showed severe meningeal irritation, and cerebrospinal fluid (CSF) examination revealed cell counts of 207/microliter (72% polynuclear cells), protein level of 300 mg/dl, glucose level of 13 mg/dl, chloride (Cl) level of 104 mEq/l, adenosine deaminase (ADA) level of 10.0 IU/l. The CSF culture was negative for Mycobacterium tuberculosis (M. tuberculosis) and direct polymerase chain reaction (PCR) for M. tuberculosis DNA was negative, but nested PCR was positive in preserved CSF samples. Marked leptomeningeal enhancement at the basilar meninges was noted by cranial MRI on gadolinium (Gd)-DTPA enhanced T1-weighted images. We diagnosed her condition as tuberculous meningitis and administered a total of 5 anti-tuberculosis drugs over about 2 months. However, during this period, both her clinical and CSF findings worsened, and she developed severe consciousness disturbance showing marked hydrocephalus on cranial MRI in August 2001. Therefore, we initiated intrathecal administration of INH 100 mg 3 times a week for progressive tuberculous meningitis. After the initiation of intrathecal therapy, both her consciousness disturbance and CSF findings were improved almost immediately. Ventriculo-peritoneal shunt operation was performed for hydrocephalus on September 26, 2001, and her clinical symptoms were further improved. To our knowledge, this is the first reported case of refractory tuberculous meningitis markedly improved by intrathecal administration of INH. Our findings suggested that intrathecal administration of INH was useful for refractory tuberculous meningitis.

We report the case of a patient presenting amenorrhea, hyperprolactinemia, headache and nuclear magnetic resonance (NMR) evidence of pituitary macroadenoma. The family history revealed that the patient's father had had a referred sporadic insulinoma, removed 25 yr before without evidence of other endocrine disorders. Physical examination evidenced a slight neck enlargement. Among biochemical and endocrinological assays performed, only hyperprolactinemia was observed. Neck ultrasonography (US) revealed a parathyroid enlargement and a 99mTcO4/MIBI scan showed two hyperplasic lesions. Considering the diagnostic suspect of multiple endocrine neoplasia (MEN1), we performed abdominal US and NMR studies, showing a pancreatic lesion compatible with neuroendocrine tumor. A total body 111In-DTPA-d-Phe1 -octreotide scan (Octreoscan) was also carried out, evidencing no pituitary tumor uptake but high uptake of the abdominal lesion. After surgery, the histological examination confirmed the two parathyroid adenomas and four non-functioning pancreatic neuroendocrine tumors. When the patient was admitted for studying the pituitary lesion and for planning the opportune therapy, an early and partially subclinical stage of MEN1 was identified, potentially already clear but otherwise undiagnosed, and the genetic state of the patient's relatives, as possible carriers of DNA mutation, was checked. The DNA study for germline mutations confirmed the clinical diagnosis of MEN1 syndrome in the patient and evidenced the same MEN1 mutation in her father and twin sister. In this case report, we would like to underline that, still today, a correct anamnesis and physical examination are the cornerstone of clinical approach to the patient. Furthermore, initial good practice approach is necessary to plan the diagnostic iter, enabling clinicians to decide upon the best orientation and interpretation of the results among several complicated and expensive exams.

Aqueductal stenosis is induced by widely various causes. These causes include congenital stenosis, tumor or inflammation. Among them vascular malformation is a very rare cause. In this paper we present a rare case of aqueductal stenosis caused by venous angioma. The patient was a 28-year-old female, who suffered from headache and double vision. On admission, CT and MRI showed lateral and third ventricular dilatation not but fourth ventricle, suggested aqueductal stenosis. Gd-DTPA enhanced T1-weighted MR image showed an abnormal draining vein passing through the orifice of the aqueduct. Angiography demonstrated the umbrella sign which was specific sign of the venous angioma. We performed endoscopic third ventriculostomy. Postoperative neuroradiological examination showed shrinkage of the ventricles and the symptom of the patient improved markedly. In the past literatures, five cases of aqueductal stenosis due to venous angioma have been reported. Although venous angioma is congenital, all five cases had been symptomatic at adult stage. Detailed evaluation of pre-and post-operative MRIs suggest that aqueductal stenosis induced enlargement of the lateral and third ventricles, which led narrowing of the suprachiasmatic cistern and the peri-mesencephalic cistern, and downward displacement of medulla and tonsil into the foramen magnum. As a result, hydrocephalus is aggravated gradually.

Ophthalmoplegic migraine is a rare syndrome in which headache is associated with ophthalmoplegia and third, fourth or sixth cranial nerves palsy. It occurs most frequently in childhood and teenagers. At magnetic resonance imaging (MRI) with gadolinium (GD-DTPA) it may be observed a transitory enhancement of the affected nerve. We present the case of a male teenager, 16 years old, with typical medical history and enhanced signal at left oculomotor nerve in cisternal portion at MRI weighted in T1 with GD-DTPA. On the control exam, eighteen months later, there was no remarkable lesion. The enhancement of oculomotor nerve at MRI is always pathological and among the differential diagnosis we must include: neoplasia (lymphoma and leukemia), infections (AIDS, syphilis), inflammatory process (sarcoidose and Tolosa-Hunt syndrome) and vascular (posterior communicating artery aneurysm).

We reported a case of X-linked lymphoproliferative syndrome (XLP) with multiple nodular lesions in the brain and lungs. A 21-year-old man was admitted because of one month history of low grade fever, headache, nausea, and amnesia. He developed agammaglobulinemia following Epstein-Barr virus infection at 3-year-old, and thereafter was administered 7.5g of immunoglobulin every 3 weeks with a diagnosis of XLP. Physical examination was unremarkable on admission. Neurological examination revealed disorientation of time, and bilateral gaze-evoked nystagmus. Neuropsychological tests demonstrated impairment of recent memory and calculation. Pleocytosis (83/microl) and increase of protein (1269 mg/dl) and IgG (141 mg/dl) in the CSF were observed. Brain MRI showed multiple nodular lesions with high intense signal on T2-weighted images and Gd-DTPA enhancement on T1-weighted images. Chest CT showed multiple nodular lesions in the bilateral lungs. The needle lung biopsy was performed, which showed infiltration of lymphocytes around the vessels. An immunohistochemical study showed that the infiltrating cells were mainly CD8 positive T lymphocytes. B lymphocyte and plasma cells were not seen. The histological findings excluded intravascular malignant lymphoma and lymphomatoid granulomatosis. Therefore we diagnosed lymphoid vasculitis. The patient developed pancytopenia caused by hemophagocytic syndrome 48 days after admission and was treated with 1 g of methylprednisolone per day for 3 days and a tapered dose of steroid (500 mg to 125 mg of methylprednisolone and 60 mg to 10mg of predonisolone) for 21 days, which resulted in the improvement of clinical features (hemophagocytic syndrome and central nervous system symptoms) and the abnormal CSF findings. The multple nodular lesions in the brain and the lungs shrank 1 month after treatment and disappeared 11 months later. There are few reports concerning lymphoid vasculitis with XLP, and no effective treatment has been described. Our case suggests that steroid therapy may be useful for the treatment of lymphoid vasculitis in XLP.

Spontaneous intracranial hypotension is an infrequent clinical entity characterized by orthostatic headache, low cerebrospinal fluid pressure, and magnetic resonance imaging findings of diffuse pachymeningeal gadolinium enhancement without previous history of head trauma or lumbar puncture. A 24 year-old healthy woman was referred after having daily headaches for two weeks. She described a headache that occurred soon after assuming an upright position and disappeared after resuming a recumbent position. The cerebrospinal fluid showed pleocytosis primarily lymphocitic, raised protein content and an opening pressure of 20 mm H2O. Magnetic resonance imaging of the head showed diffuse pachymeningeal gadolinium enhancement. Radioisotope cisternography using 99mTc-DTPA confirmed the cerebrospinal fluid leak in the thoracic region. With conservative treatment the patient improved in a few days and the headache disappeared. Radiological findings, together with a compatible clinical condition, help to establish the diagnosis of spontaneous intracranial hypotension and avoid the use of unnecessary clinical investigations.

Whereas fibrous dysplasia is a well-known, developmental skeletal disorder with a benign clinical course, fibrous dysplasia of the clivus is extremely rare and has seldom been reported. Differentiating this benign entity from more aggressive diseases involving the clivus is important for the proper management of lesions in this area. We here report a case of fibrous dysplasia of the clivus and discuss its radiographic features. The patient was 55-year-old male who had suffered from headache for months. Physical and neurological examinations found no abnormalities. The computed tomographic (CT) scan and magnetic resonance imaging (MRI) showed an abnormal mass lesion in the lower of the third clivus. On CT scan, the mass lesion exhibited a ground-glass appearance. The lesion was detected as hypointense and a mixture of hyperintense and isointense areas on T1-weighted and T2-weighted MRI, respectively. Heterogenous enhancement was noted after infusion of GD-DTPA. The patient underwent a transsphenoidal resection of the mass and the histopathologic diagnosis was fibrous dysplasia.

We report a rare cervical monostotic fibrous dysplasia with a large cyst in the C2 region in a 55-year-old man complaining of headache. MRI revealed an expanding bony tumor at the C2 spinous process. Gd-DTPA MRI showed slight enhancement around a cystic mass. We performed C2 laminectomy and removed the tumor. It was comprised of soft tissue in the C2 spinous process and right lamina and contained a large septated cyst filled with xanthochromic fluid. Histopathology confirmed fibrous dysplasia with typical woven bony trabeculae. His postoperative course was uneventful and outpatient follow-up detected no deficits. Cervical fibrous dysplasia with a distinct cyst is a rare entity and few cases have been reported in the literature. Such cysts are considered to reflect a tumor regression process. Diagnosis based on MRI and CT study alone is difficult. We suggest that these lesions be surgically resected.
