AIMS: We discuss our experience with the surgical management of scalp vascular malformation and review the literature on the subject. SETTINGS AND DESIGN: A prospective case-control study of eight patients with scalp vascular malformations admitted to our hospital between 1997 and 2002. METHODS AND MATERIALS: All the patients were investigated with selective internal and external carotid angiography. Depending upon the origin of feeding arteries, the scalp vascular malformations were classified into two categories: Group I: the primary scalp arteriovenous malformations and Group II: secondary venous dilatations. Six patients belonged to Group I and two patients were in Group II. RESULTS: Five patients belonging to Group I underwent successful excision of the arteriovenous malformation. There was no recurrence in this group. Of the two patients in Group II, one patient who had scalp vascular dilatation simulating a primary scalp vascular malformation underwent excision of the lesion. This patient developed severe postoperative brain edema and died. CONCLUSIONS: Primary scalp vascular malformation can be excised safely. However, excision of secondary scalp venous dilatation without treatment of the intracranial component can be dangerous.

We report two rare cases of primary intracranial plasma cell granuloma. The tumors probably arose from the dura and involved the cerebral parenchyma. These patients presented with clinical features of raised intracranial pressure and there was focal neurological deficit. The management issues are discussed.

Intracranial schwannoma not related to cranial nerves are unusual and rarely found in the subfrontal region. We report a case of cystic olfactory groove schwannoma in a 55-year- old male, who presented with late onset seizure without raised intracranial pressure. The tumor was excised completely.

An injury to the pharynx and esophagus is a known complication of anterior cervical spine surgery. Two cases of delayed pharyngo-esophageal perforation following anterior cervical spine surgery that resulted in fistula are presented. We postulate that graft displacement and dislodgement of implant with resulting esophageal erosion was responsible for this complication.

Penetrating injuries of the brain caused by a nail are rare. An interesting case of a patient with schizophrenia who attempted suicide by a self-inflicted penetrating intracranial injury using a nail is reported here. The literature related to this unusual case is reviewed.

Acute subdural hematoma is an uncommon presentation of the rupture of an intracranial aneurysm. We report two cases of intracranial aneurysms causing spontaneous acute subdural hematoma.
