Adrenocortical oncocytoma

Adrenocortical oncocytoma is an exceedingly rare pathological variant of an adrenal neoplasm. The pathogenesis of oncocytic neoplasms is poorly understood. Females have been reported to be affected 2.5 times more frequently than males, and left-sided lesions are more common than those on right side. This case describes a 20 years old female with right lumbar pain. She found to have a right adrenal gland mass measuring about 6 x 5 cm. A computed tomogram showed hypodense mass lesion 6 x 4.2 cm involving right adrenal gland. Differential diagnosis of non-functional adrenal adenoma was made. A laparoscopic right adrenalectomy was performed using the 3-ports lateral transperitoneal approach. Histopathology showed adrenocortical oncocytoma of adrenal gland

EEG findings in post stroke seizures: an observational study

Stroke is an important cause of epilepsy especially in the elderly. We conducted an observational study in a tertiary referral center to describe different EEG findings in patients who developed seizures after stroke. We reviewed alt EEGs that were performed for evaluation of seizures after stroke from January to December 2006 and retrospectively recorded demographic data, side of stroke, type of seizures and EEC findings. All this information was entered on a specially designed proforma. A total of 41 patients with post stroke seizures had EEG done at our laboratory that were reviewed and analyzed. Of these patients, 51.2% [n=21] were males [mean age 60.7; range 22-84 years] and 48.8% [n=20] were females [mean age 63; range 3-90 years]. The commonest seizure semiology was generalized seizure in 56.1% [n=23], focal seizures in 36.6% [n=1 5] and focal with secondary generalization in 7.3% [n=3] patients.51 .2% [n=21] had right hemispheric involvement, 26.8% [n=11] had left hemispheric involvement and in 22% [n=9] patients side of stroke was not identified. The commonest EEG finding was generalized slow waves seen in 39.0% [n=16] patients. Other abnormalities found were focal slowing in 19.5% [n=8], focal sharp and stow waves in 9.8% [n=4], focal spikes and slow waves in 4.9% [n=2], focal sharp waves in 4.9% [n=2] of the patients. Focal spike waves in 2.4% [n=1] and PLEDS were seen in 2.4% [n=1] patients. 17.1% [n=7] patients had normal EEG. Generalized seizures and generalized slowing on EEG were the commonest findings in our patients who developed seizures after stroke. The commonest epileptiform discharges were focal sharp and slow waves seen in 9.8% of patients with post stroke seizures
