Transsphenoidal encephalocele presenting as complex partial seizure disorder

A 47-year-old man presented with history of recurrent complex partial seizures of 10 years duration with normal clinical findings. Imaging showed a suspected destructive mass lesion in the sphenoid sinus with widespread erosion of the surrounding bone including the temporal base. Transnasal endoscopic sphenoidotomy showed an encephalocele mass, a rare variant of basal encephalocele. Unusual presentation of an encephalocele as a seizure disorder is described

Sciatic nerve schwannoma

Isolated peripheral nerve schwannoma, which is not a part of neurofibromatosis Type-1 or unrelated to radiation is uncommon. They usually arise from a major nerve trunk and present commonly with progressive neurological deficits. Sciatic nerve schwannoma is one such uncommon occurrence that presented with a rather common neurological presentation, sciatica, which could be excised microscopically without any sequel

Post-traumatic occlusion in vertebro-basilar system: report of two cases

OccIusions of the vertebral and basilar arteries following trauma are uncommon occurrences. Most patients present with brain stem or cerebellar dysfunction and although four vessel angiography is essential for localising the anatomic diagnosis, computed tomography of the head [CT head] is helpful in showing associated changes such as infarction, haemorrhage or hydrocephalus. Two cases form the basis of the present report. One patient developed occlusion of the cervical vertebral artery following a gun shot injury and presented with Brown Sequard syndrome and the other patient, who was treated initially for a left frontal extradural haematoma, later developed acute coma eight weeks following the injury. Angiography showed vertebro-basilar dissection, occlusion and posterior inferior cerebellar artery [PICA] pseudo-aneurysm, and computer tomography showed subarachnoid and intraventricular haemorrhage and left cerebellar infarction
