Pseudomyxoma peritonei: unusual origin from teratoma associated mucinous cystadenoma of ovary

Pseudomyxoma peritonei is an extremely rare clinical syndrome with incidence of approximately two per 10000 laparotomies. Approximately 44% of women with PMP have ovarian mucinous tumor. It is generally accepted that the ovarian involvement is secondary; PMP is nearly always gastrointestinal origin, usually from mucinous adenoma of the appendix1. Exception to this, we report a 35 years lady who presented with the complaint of abdominal pain and abdominal distention for two months, clinically and radiologically gross mucinous ascites with large abdominopelvic mass was evident. Final histopathology was reported as mucinous cystadenoma, with mature teratoma components, appendix was normal.

Processes of sand entrainment and emplacement in sand injection complexes of the Viking Graben

The Balder Field reservoir sandstone has been interpreted as remobilized from a Mesozoic parent bed. This paper seeks to address the questions raised about this unusual origin. Research and broadly analogous processes are reviewed leading to the proposal that the parent beds may have been fluidized by bedding-parallel retrogressive entrainment of Statfjord Formation sands by a connected larger source of overpressured fluids. These fluids are identified as most likely derived by lateral migration from the Viking Graben, initiated in response to early Eocene basin inversion related to North Atlantic rifting. The event probably involved breaching of the topseal in multiple places over a large section of the Utsira High. The geometry of large sills formed from small breach points and internal differentiation seen may show that the sills inflated by lateral accretion from a medial active flowing zone of turbulent, transitional or laminar flowing suspension. It is suggested that sequence-stratigraphic and structural context should be considered as additional criteria to discriminate between depositional and intruded sands.

VARIATION IN ORIGIN OF SUPERIOR THYROID ARTERY AND ITS CLINICAL RELEVANCE: A CASE REPORT

Thyroid surgeries are most common neck surgeries; hence thorough knowledge of the variations in blood supply of this gland to the surgeons is very important to prevent any alarming hemorrhage or iatrogenic damage. We found a variation in origin of superior thyroid artery on right side during routine dissection on an adult male cadaver in the Department of Anatomy, A.I.I.M.S, NewDelhi. Left superior thyroid artery was normal. Right side, superior thyroid artery was arising from common carotid artery instead of external carotid artery, just proximal to the bifurcation of common carotid artery. This variant branching pattern of superior thyroid artery is very rare. The inferior thyroid arteries did not show any unusual origin. Knowledge of such arterial variations related to the thyroid gland is immensely helpful to the surgeons to avoid damage of the vital organs in this region.

Cardiac Excrescences of Unusual Origin

Mesothelial/monocytic incidental cardiac excrescences (cardiac MICE) are a rare finding that are most often discovered incidentally either upon echocardiography or invasive cardiovascular procedures. In total, less than 50 known cases have been reported since first being discovered over 30 years ago. They are typically benign lesions; however, there has been a reported case of cardiac MICE being responsible for severe cardiopulmonary compromise and another case of the lesion embolizing leading to cerebral infarctions and ultimately death. Cardiac papillary fibroelastomas are also uncommon lesions found in the heart though they are not as rare as cardiac MICE. They are also benign and are typically attached to valvular surfaces; however, they also can be found as mobile masses. Just as cardiac MICE, they are capable of causing turbulent flow and thrombus formation and have been reported as the cause of ischemic events due to their ability to embolize. We present a case of cardiac MICE and cardiac papillary fibroelastoma in an individual who initially presented with neurologic symptoms concerning for a cerebrovascular accident. The patient was found to have a left ventricular mass composed of both cardiac MICE and cardiac papillary fibroelastomas.
