Differences in the imaging characteristic of adult medulloblastomas have been reported, including involvement of lateral cerebellar hemispheres with an extra-axial appearance. We present a case report of this rare circumstance: a 40 year old man presented with a 3 weeks history of headache, morning vomiting and left hearing difficulties. Magnetic resonance imaging revealed a left cerebellopontine angle (CPA) tumor, like a well circumscribed homogeneously enhancing mass. Through a left suboccipital craniectomy the tumor was totally removed. It presented as a cerebellopontine angle tumor, like a meningioma, and not as an intra-axial tumor. Histological analysis revealed that the tumor was composed of densely packed with highly proliferative cells that produce a dense intercellular reticulin fiber network. Inmunohistochemical analysis showed positive expression to synaptophysin, specific neuronal enolase and cromogranin. Histological diagnosis was crucial to define it as a desmoplastic medulloblastoma the present case and to perform postoperative adjuvant therapy. Neurosurgeons should be aware of the possibility that a CPA tumor is of intraaxial origin, because this increase the variability on pathological diagnosis.

Cerebellopontine-angle meningioma is a rare intracranial neoplasm. It presents a difficult problem in pregnancy. A 27-year-old multigravida presented with headache, vomiting and visual disturbances at 30 weeks' gestation and cerebellopontine angle meningioma and hydrocephalus were diagnosed. A ventriculoperitoneal shunt was placed under general anesthesia to reduce the symptoms of raised intracranial pressure and to prevent the risk of cerebellar herniation. At 32 weeks a cesarean section was performed under general anesthesia and a healthy baby delivered. A smooth induction and maintenance of anesthesia along with lidocaine and mannitol were used to prevent a rise in intracranial pressure. The intraoperative and postoperative course was uneventful. Thus, immediate neurosurgical decompression improved the patient's condition, and allowed time for fetal maturity and uneventful delivery by cesarean section under general anesthesia.

We describe the clinical, radiologic, surgical, and pathologic findings of a 29-year-old Peruvian human immunodeficiency virus-infected man with a primary parasellar meningeal leiomyosarcoma involving the left lesser esphenoidal wing and the cavernous sinus. Over a period of 13 months, he developed headache, vomiting, insomnia, and diplopia. Magnetic resonance imaging revealed a left parasellar extra-axial mass that was isointense in T1, hypointense in T2, and gadolinium-enhanced. The patient underwent subtotal resection of the tumor. The neoplasm was composed of spindle cells with smooth-muscle features. It showed moderate atypia, inconspicuous nucleoli, and scanty mitosis. No tumor necrosis was detected. The immunohistochemistry revealed strong positivity for vimentin, desmin, and smooth-muscle alpha-actin. A low-grade leiomyosarcoma was diagnosed. The in situ hybridization showed positive nuclear reactivity for Epstein-Barr virus-encoded RNA. The immunohistochemistry was negative for Epstein-Barr virus latent membrane protein 1. The main differential diagnosis of primary meningeal smooth-muscle tumors includes meningioma and peripheral nerve sheath tumors. Epstein-Barr virus has been demonstrated in most smooth-muscle tumors associated with acquired immune deficiency syndrome (AIDS). Primary meningeal smooth-muscle tumors, exceedingly rare neoplasms, remarkably affect young adults with AIDS. Comparatively, most AIDS-related visceral (nonmeningeal) smooth-muscle tumors have been reported in children. The permissiveness and tumorigenesis associated with Epstein-Barr virus may depend on the age of human immunodeficiency virus infection.

A 40-year-old male presented with hemangiopericytoma in the lateral ventricle manifesting as headaches persisting for 6 months associated with vomiting and visual obscurations for one month. Computed tomography and magnetic resonance imaging of the brain showed a large tumor in the trigone of the right lateral ventricle. The highly vascular tumor was completely excised. The histological diagnosis was hemangiopericytoma. Hemangiopericytoma is rarely located in the lateral ventricle and is difficult to differentiate from meningioma by neuroimaging methods.

A 51-year-old woman presented with a fourth ventricle meningioma manifesting as a 2-week history of dizziness and vomiting. Computed tomography (CT) and magnetic resonance (MR) imaging revealed a round mass lesion in the fourth ventricle. Thallium-201 chloride single photon emission computed tomography (201TlCl SPECT) showed high and rapid uptake on the early image and rapid washout on the delayed image. The preoperative diagnosis of meningioma could be established based on these findings. Total removal of the tumor was successfully performed. 201TlCl SPECT is useful for the preoperative diagnosis of fourth ventricle meningioma combined with CT, MR imaging, and angiography.

Meningioma is an uncommon tumor of childhood. In this group, supra tentorial forms predominate. We report the case of a 14 years old boy without any past medical history. He presented headaches, vomiting and cerebellar syndrome. CT scan shows cerebellar tumor, enhanced by contrast and surrounded by edema, looking like tuberculoma. After fail of tuberculosis treatment, the boy is operated by suboccipital approach. Histology and immuno histochemical examination show fibroblastic meningioma. Even if it is rare, meningioma can occur in childhood, without neurofibromatosis disease. It can present many points of likeness with tuberculoma and therefore biopsy is mandatory before tuberculosis drugs giving.

The authors report on a patient with hemangiopericytoma(HPC). This 43-year-old female presented severe headache, vomiting and right homonymous hemianopsia. Magnetic resonance imaging and an angiogram showed a tumor above the left transverse sinus. The patient underwent a total resection of the tumor and reconstruction of the transverse sinus without additional neurological deficits. Based on the findings shown in this case report, hemangiopericytoma should be included in the differential diagnosis from benign meningioma. Because this tumor often undergoes recurrences and metastases, we recommend a combination of radical surgical extirpation of followed by postoperative radiotherapy.

Radiation induced meningiomas (RIM) are rare late complications in patients who have received high dose irradiation for brain tumors. The mean latency period for induction of RIM in most of the series is 18.7+/-10.2 years. There are only 9 reported cases of RIM following high dose cranial irradiation with unusually short latency periods of less than 5 years. Herein, we report a child diagnosed with RIM with an unusually short latency period of 14 months. An 11-year old male child underwent gross total resection of medulloblastoma. Following surgery he received high dose craniospinal irradiation. Postoperative computed tomography scan (CT scan) after 1 month did not show features of any residual tumor, recurrence or tumor at a new site. The child was asymptomatic for 14 months and then presented with complaints of headache and vomiting. CT scan head showed multiple solid homogenously enhancing lesions in bilateral basifrontal and right basitemporal region. Histopathology of the lesions turned out to be atypical meningioma.

Granulocytic sarcoma is a rare tumor composed of immature granulocytic cells. Prognosis is poor. The dura and orbits are preferentially involved. An intracranial localization is unusual. We report the case of a 31-year-old man who was admitted with a history of headache and vomiting. The neurological examination revealed hemiplegia. Computed and tomography (CT) and magnetic resonance imaging (MRI) showed a lesion which was interpreted as a meningioma. After surgical resection, pathology examination led to the diagnosis of granulocytic sarcoma. The clinical and radiological features of this case are discussed with reference to other reports in the literature.

Intratumoral bleeding from a meningioma is very rare. We herein report a case of a foramen magnum meningioma which presented in association with intratumoral bleeding. A 49-year-old female who had been suffering from occipital headache and shoulder pain on neck motion was referred to our hospital to undergo treatment for a tumor located in the posterior fossa. Magnetic resonance imaging (MRI) demonstrated a foramen magnum meningioma which originated at the lower clivus and extended to the C2 level of the vertebral column. Marked compression and distortion of the medulla oblongata and spinal cord was also noted. Surgery was therefore planned. The patient thereafter suffered from a sudden onset of headache, vomiting and hoarseness, and was transferred to our hospital. A computed tomography (CT) showed intratumoral bleeding, which extended to the subarachnoid space and the fourth ventricle. The tumor, as well as the massive hematoma, were both immediately removed. The histological diagnosis was meningothelial meningioma. We also reviewed the pertinent literature and propose the possible mechanism for such tumor bleeding in this particular location in which the blockage of the cerebrospinal fluid caused a craniovertebral pressure gradient, which thus resulted in intratumoral bleeding.
