AbstractSchwannomas are benign tumors arising from Schwann cells which are a protective casing of nerves, composing myelin sheath and can develop in any nerve where Schwann cells are present. Most common are vestibulocochlear nerve schwannomas. Facial nerve schwannomas (FNSs) are uncommon tumors involving seventh nerve of which geniculate ganglion involvement is most common. Clinical presentations and the imaging appearances of FNSs are influenced by the topographical anatomy of the facial nerve and vary according to the segments involved. We report a case of 73-year-old man presenting with right side facial weakness of lower motor neuron type involvement. Computed tomography and magnetic resonance imaging are clinching the diagnosis. An early diagnosis is important in containing the disease facilitating early surgical intervention.

✓ A rare case of intradural chordoma is described. The literature contains seven examples of intradural extraosseous chordoma, all reported in a ventral location. This is the first reported case of a primary intradural chordoma distant from the clivus and involving both the supra- and infratentorial compartments.

Abstract The falx cerebelli is a small sickle-shaped fold of dura mater below the tentorium cerebelli, which projects forward into the posterior cerebellar notch. We report a rare case of 28 year female presented with the history of headache of six months duration off and it increased in severity and frequency over last 15 days. Imaging findings were suggestive of meningiona arising from the falx cerebelli. The lesion could be excised totally and safely.
