Frontal subcutaneous lipoma associated with interhemispheric lipoma, lipomeningocele, and corpus callosal dysgenesis in a young adult: CT and MRI findings.

Intracranial lipomas are rare incidental lesions. Rokitansky first described a corpus callosal lipoma on the posterior part of the corpus callosum in 1856. Since then many cases have been reported. We report the imaging findings of an interhemispheric lipoma extending into subcutaneous plane associated with spinal lipomeningocele and corpus callosal dysgenesis. Computed tomography and magnetic resonance imaging findings are characteristic. All cases have been reported in pediatric age group till now. Such a case in this age group has not been reported earlier.

Lymphocytic Hypophysitis Mimicking Pituitary Macroadenoma.

Lymphocytic hypophysitis is an inflammatory /autoimmune disorder that primarily involves the pituitary gland and the pituitary stalk. The common clinical presentations include headache, nausea, vomiting, fatigue, features of hypopituitarism and diabetes insipidus as well as diplopia, orbital pain and bitemporal hemianopia. We report a case of lymphocytic hypophysitis which presented as hemichorea. Neuroimaging showed a mass in the sella tursica region which, on histopathological examination was suggestive of lymphocytic hypophysitis. After excision of this mass, patient showed marked improvement in his symptoms albeit he developed panhypopituitarism. The patient was treated with pituitary hormonal replacement therapy and is currently asymptomatic.

A rare case report of bilateral internal carotid artery hypoplasia in postpartum female: Clinical spectrum and role of various modalities in diagnosis.

Congenital hypoplasia of bilateral internal carotid arteries (ICAs) is an extremely rare anomaly with less than 25 reported cases in literature till date. We present a case of a 30-year-old primigravida, who developed seizures and subsequently loss of consciousness just few minutes after the delivery of a healthy male child. To the best of our knowledge, this is the first case with bilateral ICA hypoplasia presenting in postpartum female who developed infarct in bilateral frontal region and subarachnoid hemorrhage (SAH). On a postpartum three-dimensional (3D) computed tomography (CT) angiography, bilateral ICA hypoplasia was confirmed and the manifestations of infarcts were probably the consequence of altered hemodynamics of pregnancy. In conclusion, a patient in her late pregnancy and postpartum period, having nonspecific cerebral symptoms or having suffered a cerebrovascular accident, should not only be evaluated for pregnancy or puerperium-related complications but also whenever possible a baseline screening with Doppler study of neck vessels and a noncontrast magnetic resonance imaging (MRI) angiography of neck and cerebral vessels should be performed to rule out congenital anomalies.
