Acute proximal occlusion of a nonaneurysmal abdominal aorta and renal arteries detected by renal imaging.

This report describes an unusual case of extensive vascular thrombosis involving the abdominal aorta and its branches. An 81-year-old man was admitted for anuric acute renal failure and congestive heart failure. An initial renal scan, performed to assess for the possibility of renal arterial embolus, showed scintigraphic evidence of obstruction of the proximal abdominal aorta, as well as markedly decreased perfusion to both kidneys and to the liver and spleen. The patient's condition progressively deteriorated and he expired. An autopsy showed total thrombotic occlusion of a mildly atherosclerotic nonaneurysmal abdominal aorta extending from the level of the superior mesenteric artery distally to the iliac arteries. There was involvement of the renal arteries and the splenic and superior mesenteric arteries by thrombosis. Thus, renal scintigraphy accurately detected the level of obstruction, which was further confirmed by autopsy.

New neurological findings in trisomy 13.

The patient in this report had many of the classic neuropathologic stigmata of trisomy 13, including retinal dysplasia, arrhinencephaly, holoprosencephaly, single external nare and granular cell heterotopias in the cerebellum and microthalmia. In addition, several new findings apparently were present in this case. The neuropathologic entities were as follows: (1) herniation of the cochlear nuclei into the eighth cranial nerve bilaterally to the transition of central to peripheral myelin; (2) gray matter present in eleventh cranial nerve bilaterally; (3) arteriovenous malformations of letpomeningeal and intracerebral vessels; (4) arachnoid cyst at the cauda equina; and (5) retinal pigment epithelium within the optic nerve.
