BACKGROUND The classic infratemporal fossa type A approach (IFTA-A) permits superior and anterior exposure of the jugular foramen. The transcondylar-transtubercular extension facilitates posteroinferior and medial access to the jugular foramen. The purpose of this study was to present the IFTA-A with transcondylar-transtubercular extension and to assess its surgical results. METHODS A review ...

In most healthy people morning awakening is associated with a burst of cortisol secretion: the cortisol awakening response (CAR). It is argued that the CAR is subject to a range physiological regulatory influences that facilitate this rapid increase in cortisol secretion. Evidence is presented for reduced adrenal sensitivity to rising levels of ACTH in the pre-awakening period, mediated by an e...

Pheochromocytoma (PCC) is a rare neuroendocrine catecholamine-secreting tumour of the adrenal gland. It originates from chromaffin cells found within medulla or extra-adrenal paraganglia. We present case report 24-year-old female who presented with hypertension, headache, palpitations, chest pain and blurry vision. On ultrasound evaluation, right suprarenal mass was noted, which further evaluat...

Paragangliomas (PGLs) derive from either sympathetic chromaffin tissue in adrenal and extra-adrenal abdominal or thoracic locations, or from parasympathetic tissue of the head and neck. Mutations of nuclear genes encoding subunits B, C, and D of the mitochondrial enzyme succinate dehydrogenase (SDHB 1p35-p36.1, SDHC 1q21, SDHD 11q23) give rise to hereditary PGL syndromes PGL4, PGL3, and PGL1 re...

A well developed extra-adrenal cortical body with an axis of 200-700 micron was found in eighteen of thirty adult male Wistar rats under a stereomicroscope. All eighteen bodies were located between the kidneys. Blood vascular beds of sixteen of the eighteen bodies were reproduced with a methacrylate casting medium and observed with a scanning electron microscope. The extra-adrenal cortical body...

BACKGROUND Newer, energy-based devices like the ultrasonic coagulator (Harmonic Scalpel, Ethicon Endo-Surgery, Inc., Cincinnati, OH) and the LigaSure vessel-sealing system (Valleylab, Boulder, CO) are increasingly being used in advanced laparoscopic procedures. Use of these devices has resulted in shorter operative time, less blood loss, and lower conversion rates. We present our experience wit...

An extra-adrenal paraganglioma is a rare tumour derived from chromaffin cells of sympathetic ganglia. This report documents a rare case of a non-functional aortocaval paraganglioma in a 24-year-old woman with persistent abdominal pain. Computed tomography revealed a solid mass, measuring 2.5x3cms, localized between the celiac trunk and superior mesenteric artery in aortocaval location along wit...

Retroperitoneal paragangliomas are uncommon neuroendocrine tumors which are derived from extra-adrenal paraganglioma with various clinical signs and symptoms. Although most extra-adrenal paragangliomas are histologically benign, some tumors can synthesize and secrete excess catecholamine from the tumor. Excessive production of catecholamine causes numerous cardiovascular manifestations such as ...

INTRODUCTION Paraganglioma is an extremely rare catecholamine-producing tumor during pregnancy. Paraganglioma carries high risks of fetal and maternal mortality during pregnancy. We report a pregnant woman with paraganglioma in the second trimester. CASE DESCRIPTION A 24-year-old pregnant woman presented with severe hypertension in the 17th week of gestation. Hormonal examination and Magnetic...
