A case of extensive left-sided facial atrophy of Romberg.

Progressive facial atrophy or Parry-Romberg syndrome is characterized by slowly progressive facial atrophy involving skin, subcutaneous tissue, cartilage and bony structures. Apart from facial atrophy, it can be associated with diverse clinical manifestations including headache, partial seizures, trigeminal neuralgia, cerebral hemiatrophy and ocular abnormalities. The exact etiology is unknown although sympathetic system dysfunction, autoimmune disorders, focal scleroderma, trauma and genetic factors have been postulated.

Boomerang sign: Clinical significance of transient lesion in splenium of corpus callosum.

Transient signal abnormality in the splenium of corpus callosum on magnetic resonance imaging (MRI) is occasionally encountered in clinical practice. It has been reported in various clinical conditions apart from patients with epilepsy. We describe 4 patients with different etiologies presenting with signal changes in the splenium of corpus callosum.

An unusual case of Takayasu's arteritis: Evaluation by CT angiography.

Takayasu's arteritis is a chronic, idiopathic, medium and large vessel vasculitis involving aorta and its main branches. Frequent neurological manifestations include postural syncope, seizures, and blindness. Stroke, as presenting feature of Takayasu's arteritis, is unusual.

Midbrain neurocysticercosis presenting as isolated pupil sparing third cranial nerve palsy.

Brainstem alone is involved very infrequently in patients with neurocysticercosis; usually, it occurs in association with disseminated form of the disease. Isolated involvement of the third nerve is commonly due to vascular causes. We are reporting a case due to cysticercus lesion presenting as isolated third-nerve involvement with sparing of the pupil.

Bilateral cavernous sinus syndrome and bilateral cerebral infarcts: A rare combination after wasp sting.

Neurologic manifestations of wasp sting are uncommon and delayed in onset (Sachdev et al. [1]). Various central and peripheral nervous system presentations have been described including wasp sting encephalopathy, cerebral infarction, optic neuropathy, polyradiculopathy, neuromuscular junction disorders, etc [1].
