ABSTRACT
Facial nerve neurinomas are rare. The tumours arising from the geniculate ganglion may grow anteriorly and superiorly and present as a mass in the middle cranial fossa. Only a few cases of facial nerve neurinomas presenting as middle cranial fossa mass have so far been reported. These tumours present with either long standing or intermittent facial palsy along with cerebellopontine angle syndrome.

Intramedullary epidermoid cysts of the spinal cord are rare tumours, especially those not associated with spinal dysraphism. Around 50 cases have been reported in the literature. Of these, only seven cases have had magnetic resonance imaging studies. We report two cases of spinal intramedullary epidermoid cysts with MR imaging. Both were not associated with spina bifida. In one patient the tumour was located at D4 vertebral level, while in other within the conus medullaris. The clinical features, MR imaging characteristics and surgical treatment of such rare intramedullary benign tumours are discussed, and the relevant literature reviewed.

Ventricles can be involved in different ways in neurotuberculosis, however, the occurrence of intraventricular abscess has been rarely reported. We report a young woman who had intraventricular tubercular abscess. Cranial computed tomographic scan showed hypodense ring enhancing lesion in the right lateral ventricle with unilateral hydrocephalus. She underwent parasagittal craniotomy with total excision of the lesion. The pus obtained from the lesion was teeming with acid fast bacilli.

CSF rhinorrhoea is associated with high morbidity and mortality. Bone and dural defects may result from trauma or enlarging 'pitholes' or breach in lateral recess of sphenoid sinus. Unless surgically corrected, they tend to cause meningitis and rhinorrhoea. Unusually delayed rhinorrhoea is a diagnostic problem.
