While majority of the meningiomas can be diagnosed on contrast enhanced computerised tomography (CT) scans, few of them can have atypical appearances, which may be difficult to distinguish from those seen in glial tumours. Six atypical cases of meningioma having hypodense appearances on CT scan are described.
Mutism and oropharyngeal apraxia are unusual complications of surgery on the cerebellum. They usually occur in children undergoing surgery for midline cerebellar tumours. Adults are rarely affected. The pathophysiology of the syndrome, which is reversible, is uncertain with possible involvement of vermian and paravermian structures. Two patients--one child and one adult--who developed mutism after cerebellar surgery are presented.
Metastatic lesions in the cerebellopontine angle are rare. We encountered one such metastatic lesion from clear-cell renal carcinoma that had a striking clinical appearance, bleeding from the ear and multiple lower cranial nerves' involvement. While the overall prognosis in CNS metastasis from systemic malignancy is gloomy, useful palliation can be achieved in patients with solitary lesions.
Traumatic internal carotid artery aneurysm presenting with epistaxis is rare. Epistaxis often occurs after a delay of weeks to months following head injury. The present case had bouts of recurrent massive epistaxis nearly four months after head injury. Diagnosis was made after carotid angiography. Epistaxis ceased after ipsilateral carotid ligation.
Epidural tuberculoma in the spine is a rare lesion and its pre-operative distinction from tumour is usually not possible. One such case who presented with radiological appearance suggestive of spinal tumour is described.

Discitis and vertebral collapse are rare but serious complications of lumbar puncture. Clinical profile, management and course of post lumbar puncture discitis in five patients is presented. Such a complication should be kept in mind whenever any invasive procedure is carried out on the spine.
Air in epidural haematoma is an uncommon finding. It is usually seen if epidural haematoma is associated with fracture involving one of the air sinuses, but can be seen at times in the absence of any demonstrable fracture on the CT scan. Seven such cases are described in the present communication and the significance of this finding discussed.
