Surgical management of a thoracic chordoma: A case report and literature review.

BACKGROUND: Chordomas are rare benign, but locally aggressive tumors that are regularly encountered in the clivus and sacrum. Although they are rarely found in the thoracic spine, they can contribute not only to local bone destruction and spinal instability, lead to cord compression, and major neurological deficits. CASE DESCRIPTION: A 56 year-old-male originally underwent a T12 laminectomy with debulking for a thoracic chordoma. Two years later, the lesion recurred contributing to a significant paraparesis. The new MR showed a T2 hyper intense lesion with huge epidural extension that warranted a 360° surgical decompression and fusion. The histopathology from both surgeries confirmed the diagnosis of a chordoma. CONCLUSION: Combined 360° decompression and fusion was warranted to resect a T12 chordoma that recurred 2 years following an original laminectomy with debulking procedure.

Persistence of a trigeminal artery associated with a posterior meningeal artery aneurysm: case report and literature review.

A 59-year-old female presented with severe headache and trouble of consciousness. The CT showed a subarachnoid hemorrhage FISHER IV with a hematoma of the right cerebellum. The angiography discovered a persistent left trigeminal artery associated with an aneurysm of the right posterior meningeal artery. The attempt of embolization failed and the patient suffered cerebral vasospasm and died. The persistence of a trigeminal artery is found in 0.1-0.6% of the population. It is the most frequent embryological carotid-vertebral anastomosis. It appears at the fifth week of development and disappears when the embryo reaches 5-7 mm. This embryological persistence is associated with numerous vascular abnormalities. The literature review showed the presence of those aneurysms in the trigeminal artery itself or the communicating artery. The association that we described is the first to our knowledge. Therefore, this association is particular and interesting to expose.

Unusual coexistence of an epidermoid cyst with an atypical meningioma: Case report and review of the literature.

BACKGROUND: Coexistence of multiple primary intracranial tumors of different cell types has rarely been documented; the association of a meningioma and a glioma has been reported as the most common combination. Hereby, we report an unusual case of a temporal epidermoid cyst coexisting with an atypical meningioma. CASE PRESENTATION: A 37-year-old male presented with progressive symptoms of raised intracranial progression with progressive loss of vision without any neurological deficit. On admission, magnetic resonance imaging (MRI) revealed a right frontal lesion appearing hypointense T1, hyperintense T2 slightly enhanced after gadolinium and a second right temporal, isointense T1, hyperintense T2 non-enhancing lesion. A right frontotemporal craniotomy was performed that revealed two distinct lesions: The whitish temporal lesion with the pearl appearance reminding of an epidermoid cyst, the second lesion was extraaxial fibrous lesion arising from the falx. Pathology confirmed an atypical meningioma WHO Grade II and an epidermoid cyst. CONCLUSION: The simultaneous occurrence of primary intracranial tumors of different cell types is rare. Epidermoid cysts are slow growing lesions believed to arise from inclusion of ectodermal elements during neural tube closure, while meningiomas arise from arachnoidal cells; their association has rarely been reported previously.

Primary glioblastoma of the cerebellum in a 19-year-old woman: a case report.

INTRODUCTION: Cerebellar glioblastoma is an uncommon adult lesion. The pathogeny and prognosis of cerebellar glioblastoma are still incompletely elucidated. CASE PRESENTATION: We report the case of a 19-year-old Moroccan woman. A neurologic examination revealed the presence of cerebellar signs. A diagnosis of cerebellar glioblastoma is rarely made before surgery. An encephalic computer tomography scan and magnetic resonance imaging increased the accuracy of defining the nature of the lesion. Magnetic resonance imaging showed a heterogeneously enhancing mass in the vermis and the right cerebellar hemisphere. After surgery, glioblastoma was histologically confirmed. Post-operative radiotherapy followed. The outcome of our patient was favorable after one year of follow-up. CONCLUSIONS: We report an unusual case of cerebellar gliobastoma. Cerebellar glioblastoma multiforme should be considered in the differential diagnosis of a cerebellar mass lesion.
