An extremely rare foramen magnum meningioma associated with an arachnoid cyst in the lateral cerebellomedullary cistern occurred in a 65-year-old female presenting with dizziness. Neuroimaging revealed a meningioma at the left lateral edge of the foramen magnum and an arachnoid cyst mainly located in the right lateral cerebellomedullary cistern, compressing the medulla oblongata bilaterally. After fenestration of the cyst wall and tumor removal, the clinical symptoms ameliorated. We recommend that where a foramen magnum tumor coexists with an arachnoid cyst of the posterior fossa, the tumor should be removed after shrinking the cyst to obviate the need for brainstem retraction.

Cystic meningioma is rare and said to account for 1 to 2% of all types of meningioma. Here we report two cases of cystic meningioma. Case 1 is a 25-year-old man. He had suffered from sporadic epileptic seizure for about two years until the first CT was performed. It revealed a large cystic lesion at the right parietal region in touch with the midline structure. A nodular high density area was delineated in the contrast enhanced CT on the medial wall of the cyst. He showed no neurological abnormality at all. Case 2 is a 56-year-old female who had been complaining of memory disturbance, and an episode of sudden dizziness followed by a syncope that lasted for a few minutes. Neurological examination revealed slight right hemiparesis, right homonymous hemianopsia and left papilledema. A large cystic lesion was delineated at the temporal region in the plain CT, and no positively enhanced region could be found in the contrast enhanced CT. After surgical removal of the tumors, both cases were identified as cases of meningioma. They were diagnosed histopathologically as a fibroblastic meningioma and a meningotheliomatous meningioma respectively. The wall of the cyst consisted of the cortical surface per se in both cases. Preoperative diagnosis of such cases and the mechanism by which the cyst is formed were also discussed.

Choroid plexus papillomas in the posterior fossa can present with different clinical signs and symptoms. The tumors in the patients we discuss in this article originated from different sites of the choroid plexus. One patient, who had a fourth ventricle papilloma, experienced unsteady gait and episodes of dizziness over many years. The tumor was cystic an calcified, and adherent to the brain-stem. The second patient had only signs of increased intracranial pressure. A soft tumor was located in the cerebellomedullary cistern. The third patient, with a papilloma in the cerebellopontine angle, complained of hearing loss. This tumor was firmly adherent to the dura mater and looked exactly like a meningioma. The appearance on computed tomography scan, the macroscopic aspect, and the vascular supply of a papilloma in the posterior fossa can vary considerably.

Angiographically occult arteriovenous malformations not associated with clinically recognizable intracranial hemorrhage appear to be rare. We are reporting three cases of histologically proven arteriovenous malformations of the brain that were angiographically occult. These cases presented with seizures or attacks of dizziness, and were detected by computed tomography scan, radionuclide scan, or both. The preoperative diagnosis was granuloma in the first case and meningioma in the other two. After surgical exploration, biopsy revealed an arteriovenous malformation in each case. A review of 47 cases in the literature is tabulated and etiologies of the angiographically occult arteriovenous malformations are discussed. The routine use of computed tomography scan and timely, appropriate surgical intervention with the operating microscope for the removal of these deeply situated lesions is necessary for the diagnosis and therapy.

In a lot of 3 patients with olfactory meningioma, one patient drew particular attention by the particularities of its evolution, which was asymptomatic for a long time and atypical. The disease started at the age of 38 with asthenia, headaches, dizziness and X-ray images of left parasellar calcified brain tumour, without neurological signs of a focus at any of the repeated clinical or paraclinical examinations. After eight years focal signs appears: left pyramidal irritation, absences, left hyposmia, without altered visual acuity or conclusive scintigraphic and EEG alterations. Left carotid arteriography indicated a space-occupying process. The disease progressed slowly with left hemiparesis and corresponding effects. A diagnosis of "left olfactory meningioma" was established in the Neurosurgical Clinic, Bucharest. The situation deteriorated in 1977: total left anosmia, Jacksonian seizures, sometimes generalized, uncinate fits, paroxysmal headaches, amnesia disturbances and marked right hemiparesis. Recent scintigraphic and EEG alterations likewise lent support to a diagnosis of brain tumour. The existence of calcified, asymptomatic, trailing brain tumours, with an atypical and late evolution of unilateral olfactory meningioma, without Foster-Kennedy syndrome, demands from the beginning close surveillance and complex investigations, since a prolonged absence of anosmia and focal phenomena does not exclude the possibility of a meningioma of the olfactory groove, and may often lead to errors of diagnosis.

Many Jewish immigrants from North Africa in the late 1950s were treated with low-dose irradiation of the scalp for tinea capitis. In 2 such patients, a 47-year-old man and a 43-year-old woman, both with long histories of headaches and dizziness, meningiomas were found. There is a well-known correlation between low-dose irradiation of the scalp and development of meningioma. Therefore, in immigrants from North Africa with prolonged headaches and dizziness, there should be a careful history with regard to irradiation of the scalp and investigation to exclude meningioma.

A case of long survival of brain tumor (well differentiated adenocarcinoma) was reported. A 55-year-old man was admitted in January, 1986, because of a one month history of progressive headache, dizziness and gait disturbance. CT scans revealed an enhancing tumor in contact with the falx in the right frontal lobe. The tumor was totally removed. The histopathological diagnosis was that of a well differentiated adenocarcinoma. The primary site of the adenocarcinoma was not detected. No chemotherapy or radiation therapy was given. Four years and 7 months after surgery CT scans demonstrated a recurrent tumor as a bilaterally expanding falx meningioma. Nearly total removal of the tumor was again performed and diagnosed as adenocarcinoma. Examinations to detect the primary site and other metastatic lesions were negative again. On May 1993, the patient died because of the intracranial dissemination of tumor without extracranial lesions. The period from the first operation to his death was 7 years and 5 months. This is a case of long survival of intracranial cancer, which was considered as a metastatic tumor, though the primary site and other metastatic lesions were not detected. The tumor in this case showed the atypical features of a metastatic adenocarcinoma. For example, the primary and recurrent tumors resembled a parasagital or falx meningioma in shape and they grew slowly. Therefore, there is a possibility that the tumor was actually a primary adenocarcinoma, which might have arisen from the embryologically migrated cells of the mucous membrane or from ectopic epithelial cells.

The clinical manifestations, surgical treatment and postoperative results of three patients with gangliocytomas of the cerebellum (Lhermitte-Duclos disease) are presented. Particular attention is placed in one of the cases, that of a young woman with a short clinical history of episodic symptoms of intracranial hypertension, dizziness and ataxia, with a concomitant frontal meningioma and in the general context of a multiple hamartoma syndrome (Cowden disease). The possible relationship between both diseases is contemplated, since they can be the extremes of a wide spectrum of a peculiar form of phakomatosis.

The majority of cerebellopontine angle (CPA) tumors are acoustic neuromas (AN). However, an intracranial meningioma may occur at this site and will produce symptoms similar to an AN. The most common presenting symptoms of CPA meningiomas are hearing loss, tinnitus, dizziness and dysequilibrium. It cannot be easily distinquished from an AN only on the history and physical examination. Even with an audiogram, evoked response audiometry (ERA) and vestibular function tests, it still cannot be distinquished. CT scan and MRI are helpful in differentiating these two tumors radiographically. In this article, we report two cases of CPA meningiomas which presented with otologic symptoms. The diagnosis and treatment of CPA meningioma is discussed.

The CSF-pressure-lowering effects of indomethacin in seven patients with idiopathic intracranial hypertension and one patient with symptomatic intracranial hypertension due to a non-space-occupying meningioma are reported. CSF opening pressure between 350 and 500 mm H2O (mean 400 mm H2O) was promptly reduced by 80 to 200 mm H2O (mean reduction, 139 mm H2O) for at least 10 minutes in all patients after IV administration of 50 mg indomethacin. Four patients had mild and transient side effects (dizziness). Indomethacin might be an alternative drug for treatment of intracranial hypertension.
