Meningiomas are slow-growing benign lesions that constitute ∼ 25% of primary intracranial tumours. Extracranial meningioma of the sphenoid sinus is extremely rare and may arise from ectopic arachnoid nests left behind during embryonic development. We present the case of a 61-year-old woman with left oculomotor nerve paralysis. Magnetic resonance imaging (MRI) revealed a 43 × 31 × 33 mm mass in ...

A 21-year-old man presented with an extremely rare case of locked-in syndrome caused by a metastatic brainstem tumor manifesting as quadriplegia, lower cranial nerve pareses, and irregular respiration. Cranial magnetic resonance imaging revealed a large pontomedullary tumor. An emergency operation was performed via a posterior fossa approach and the tumor was grossly totally removed. The histol...

BACKGROUND Cranial dermal sinuses are rare and occur most frequently in the posterior fossa and along the midline. Likewise, supratentorial dermoid cysts are very uncommon. METHOD We report a unique case of an adult female patient with both a supratentorial dermoid cyst and an incomplete dermal sinus tract. RESULTS The patient is a 31-year-old female, who presented with a new onset complex ...
