Cranial magnetic resonance imaging abnormalities were observed in 8 children (5 boys, 3 girls; ages 4-14 years) with neurologic problems following infection by Borrelia burgdorferi, the etiologic agent of Lyme disease. Neurologic features included headache (6), behavioral changes (5), facial palsy (2), papilledema (2), papilledema with diplopia (1), disturbance of sleep pattern (2), and carpal tunnel syndrome (1). Two MRI studies demonstrated multiple focal areas of increased signal intensity in white matter on long TR (both proton-density and T2-weighted) images.

A 54-year-old woman developed headache and slight fever. When she consulted a physician, she could not move either of her eyes to the right. Cranial CT scan revealed no significant findings. Lumbar puncture was performed and CSF examination showed the cell count of 10,304/mm3, glucose level of 10 mg/dl, and total protein value of 270 mg/dl. Her symptoms and laboratory findings suggested meningitis and she was admitted to our hospital. Neurological examination revealed bilateral dilated pupils with sluggish light reflex, right gaze palsy, and hypesthesia of the left side of her face. A diagnosis of tuberculous meningitis was established by a positive test for acid-fast bacillus in CSF, and anti-tuberculous therapy was started at once. One month after the onset of symptoms, her main complaints were double vision and cerebellar ataxia. Both CT and MRI revealed a right brain-stem lesion. Pre-contrast CT could not clearly visualize the lesion but with contrast medium a homogeneously-enhanced circular lesion was shown. MRI on T2WI demonstrated the right brain-stem lesion to have a central bright core with hypointense periphery, which in turn was surrounded by hyperintensity. The lesion appeared isointense with cerebral white matter and the "central bright core" area was demonstrated to be slightly hypointense on T1WI. On post-contrast T1WI (with Gd-DTPA), the lesion showed strong homogeneous enhancement. The CT and MRI findings indicated a brain-stem tuberculoma, which was regarded as the cause of the ocular movement paralysis and cerebellar ataxia. As the clinical symptoms gradually resolved with anti-tuberculous treatment, the MRI appearance of the lesion also improved.(ABSTRACT TRUNCATED AT 250 WORDS)

A 45 year-old woman with no history of familial disease presented with multiple cutaneous and cerebral cavernous angiomas. The diagnosis rested on biopsy for cutaneous angiomas and on MRI for cerebral angiomas. The clinical manifestations of cerebral angiomas were headaches and a cerebellar syndrome, the latter most probably due to progressive growth of cerebellar angiomas. Systematized cavernous angiomatosis is characterized by multiple angiomas of the brain and other viscera and is considered to be a phacomatosis.

Macroprolactinomas have been well documented in men over the past several years. By contrast, to the best of our knowledge, there have been no reports of microprolactinomas in men. We describe here 14 cases of microprolactinomas occurring in male patients (14 to 53 years old) and discovered on the basis of endocrine symptoms. Nine patients complained of impotence and/or decreased libido, 8 had gynecomastia with or without galactorrhea, 1 had undergone incomplete puberty. All patients had hyperprolactinemia (225 +/- 65 micrograms/l, mean +/- SEM, N less than 13 micrograms/l); plasma testosterone levels were low in 9 (162 +/- 33 ng/dl, mean +/- SEM; N = 308 - 876 ng/dl), while plasma luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels and their responses to LH-releasing hormone (LHRH) were normal in all cases. Among the 14 patients, 12 had no hypopituitarism and 2 had only partial corticotrope insufficiency; none had visual disturbances and only one complained of headaches. The sella turcica was normal in size and shape in 2 cases but a double floor and/or a thinner part of the floor was observed in 12. CT scan of MRI demonstrated in all cases an intrasellar microadenoma with a mean size of 7 mm (range, 3 to 10 mm) and no preferential localization. One patient was treated with bromocriptine, while the others underwent surgery via the transsphenoidal route. Immunocytochemistry demonstrated immunoreactive-prolactin (IR-PRL) cells in all the adenomas. Surgery resulted in normalization of plasma PRL in 11 of the 13 patients and in lowering PRL levels in the others 2.(ABSTRACT TRUNCATED AT 250 WORDS)

Nine patients with a recurrent malignant glioma were treated with repeated intracavitary or intracerebroventricular injections of human recombinant interleukin-2 (rIL-2) alone or in combination with systemic interferon-alpha (IFN-alpha). Five patients received only rIL-2 and four were treated with rIL-2 plus subcutaneous injections of IFN-alpha. Therapy was administered on a Monday, Wednesday, Friday schedule for up to 10 weeks, beginning with a dose of 10,000 IU rIL-2/injection. Doses were escalated every two weeks until some toxicity was apparent. The maximum amount of rIL-2 any one patient in this group received was 580,000 IU. Patients on combination immunotherapy were held at an rIL-2 dosage of 10,000 IU while IFN-alpha, which began at 3 million IU, was escalated every other week up to 18 million IU/dose. They were then held at that IFN-alpha dosage and rIL-2 was increased to 50,000 IU. The total amount of rIL-2 and IFN-alpha any one in this group received was 510,000 IU and 417 million IU, respectively. Repeated injections of 10,000 IU rIL-2 were well-tolerated by all nine patients and no change in their functional status was seen. At doses at 50,000 IU rIL-2, increased edema around the tumor cavity was observed by MRI/CT scand in 3/5 patients and clinical side-effects in the form of somnolence and headache along with some morbidity specifically associated with tumor location were also seen. Patients receiving rIL-2+ IFN-alpha showed progressive fatigue, muscle weakness, and occasionally nausea. Two of these patients showed increased peritumoral edema on MRI/CT scan.(ABSTRACT TRUNCATED AT 250 WORDS)

We report two patients with spontaneous intracranial hypotension. In addition to the cardinal features of a postural headache and a low CSF pressure, the patients also had subdural fluid collections demonstrated by head MRI. In both patients, radionuclide cisternography revealed a CSF leak along the spinal axis and rapid accumulation of radioisotope in the bladder. CSF leakage from spinal meningeal defects may be the most common cause of this syndrome. The headache is a consequence of the low CSF pressure producing displacement of pain-sensitive structures. Associated symptoms, including tinnitus and vertigo, and subdural fluid collections are presumably from hydrostatic changes among intracranial fluid compartments that occur at low CSF pressures. Methods of treatment are identical to those for post-dural puncture headaches. Epidural blood patches and epidural saline infusions have rapidly ameliorated the symptoms of spontaneous intracranial hypotension.

In this paper we reported a familially occurred cavernous angiomas (CA) of the central nervous system (CNS). Case 1 was a 14-year-old female with an initial symptom of transient motor and sensory disorders of the right upper extremity. On examination she had a cutaneous angioma and no neurological deficit. CT and MRI revealed two lesions in the brain. These lesions were removed surgically and were diagnosed histologically as CA. Case 2 was a 45-year-old female, the mother of case 1, with a long standing headache. She had a cutaneous angioma and no neurological deficit. CT and MRI revealed a CA in the brain and a one in the cervical cord. Case 3 was an 11-year-old female, the cousin of case 1, with an initial symptom of left hemiparesis. On examination, she had a cutaneous angioma and left hemiparesis. CT revealed two lesions in the brain. These lesions were removed surgically and were diagnosed histologically as CA. Familial CA of the CNS is relatively rare and the reported cases were 24 families consisted of 70 cases. We analyzed the reported cases to clarify the specificities of the familial cases. In the familial cases, CAs were apt to be multiple and were located more frequently in the posterior fossa than in the non-familial cases. In some familial cases, the vascular anomalies of the CNS other than CA or CA of the skin or retina were also revealed. Because of high incidence (89%) of the hemorrhage from the histologically verified CA, operation should be carried out even in the cases of CA with mild or no symptom, if the lesion is accessible surgically.

A case of anaplastic astrocytoma following radiotherapy for growth hormone secreting pituitary adenoma is presented with a review of the literature. A 43 year old female was admitted with the signs of acromegaly and hypertension. An eosinophilic pituitary adenoma was subtotally removed by transsphenoidal approach, and followed by 60 Gy irradiation using a 2 x 2 cm lateral opposed field. Fourteen years later at the age of 57, she suffered from headache, recent-memory disturbance and uncinate fits. CT scan and MRI disclosed ring-like enhanced mass lesion in the left temporal lobe, corresponding to the previous irradiated field. 18F-FDG PET showed hypermetabolism at the lesion. Left frontotemporal craniotomy was performed, and a reddish gray gelatinous tumor containing necrotic center and cyst was partially removed. Histologically, the tumor consisted of hypercellular astrocytic cells with perivascular pseudorosette. Coagulation necrosis at the center of the tumor, and hyalinosis and fibrosis of the blood vessels in and around the tumor, which might have been caused by the antecedent radiotherapy, were recognized. Postoperative radio- and chemotherapy were given, however, she expired 13 months after the operation. Seven cases, including ours, of malignant glioma following radiotherapy for pituitary adenoma were reported in the literature. A total dose of irradiation varies from 45 to 95 Gy with a mean of 50 Gy. The period of latency before tumor occurrence ranges from 5 to 22 years with a mean of 10 years. The differentiation of radiation-induced gliomas from radionecrosis of the brain is also discussed.

Some pituitary hormones secrete hormones while others do not. Nonsecreting tumors can interfere with normal pituitary hormone secretion and produce tumor symptoms and signs like headaches and visual field defects. The most frequent hormone-secreting tumors are prolactinomas. Growth hormone or ACTH or gonadotropin or gonadotropin-alpha and beta chain-producing tumors are less frequent, TSH producing tumors are extremely rare. The most important elements of the diagnostic work-up are clinical signs and symptoms, assessment of pituitary function (measurement of TSH, free T4, LH, FSH, oestradiol/free testosteron, growth hormone, IGF-1, prolactin, ACTH, Cortisol, serum and urine osmolality), CT and/or MRI and, in patients with large tumors, a visual field exam. The treatment of choice of pituitary tumors is often surgery. Alternative therapies are radiation treatment (in nonoperable patients or when hormone levels are persistently elevated after pituitary surgery) and drug treatment (dopamine agonists in hyperprolactinemia, somatostatin analogues in acromegaly). Pituitary hormone deficiencies are treated depending on the specific deficiency with thyroxine, cortisone, oestrogen/gestagen/testosterone gonadotropines or ADH analogues.

11 cases of cerebral venous thrombosis in adults are reported. Main clinical signs are: intracranial hypertension (headache, nausea, papilledema in 7 cases, loss of consciousness in 6 cases, neurological deficit in 6 cases, seizure in 4 cases. 1 patient is dead, who did not receive heparin treatment. Delay before diagnosis is between 2 and 20 days, and is shortened when arteriography or MRI are available and prescribed. At least one (or several) CT examination was performed in 10 patients. Direct signs of thrombosis are uneasily detected without contrast injection, seen here in 4 cases. Empty delta sign is observed in 7 patients, lately in 4 cases, and once only afterwards. Cerebral infarction is visualized in 7 cases over 10. Its features frequently seem evocative for cerebral venous thrombosis: triangularin 4 cases or nodular shape in 3 cases with hemorragic infarct in 7 cases, with bilateral topography in 6 cases, in frontal or central areas in 7 cases. 6 patients had a MRI examination. All cerebral infarctions appeared haemorragical, even at early stages. During subacute period, venous thrombosis is constantly and easily detected by the mean of methemoglobin high signal intensity on T1 weighted images. The prediagnosis delay is short, without necessity of arteriography. MRI should take the place of CT and arteriography in investigation of a clinically suspected cerebral venous thrombosis.
