Rapid progression of a splenic aneurysm due to segmental arterial mediolysis: a rare cause of acute pancreatitis.
Abstract Background The etiology of acute pancreatitis can be manifold, beside the usual causes. We are reporting an unusual cause that triggered acute pancreatitis. Patient & results A 50 year-old male experienced attacks of acute pancreatitis (abdominal pain and elevated amylase and lipase) during sexual arousal. Serial imaging showed a rapidly-progressing, partly-thrombosed splenic artery aneurysm, with local compression of the pancreas. After angiographic coiling, the attacks subsided. Further angiography revealed additional aneurysms consistent with segmental arterial mediolysis at other sites of the body. Molecular analysis regarding Ehlers–Danlos-syndrome and genetic factors for panc…
Angiogenesis of cancer of the cervix. Contrast-enhanced dynamic MRT, histological quantification of capillary density and lymph system infiltration
Purpose: It was the aim of this project to examine (i) the relationships between contrast-enhanced dynamic MR imaging derived characteristics and histologic microvessel density counts – a recognized surrogate of tumor angiogenesis – from tumors in patients with primary or recurrent cancer of the uterine cervix, and (ii) to correlate these parameters with lymphatic involvement (i. e. lymphatic channels) to assess tumorbiological aggressiveness in terms of lymphatic spread. Materials and methods: Pharmacokinetic MR imaging parameters (amplitude A, exchange rate constant k 21) were derived from contrast-enhanced dynamic MR imaging in thirty-three patients with biopsy proven cancer of the uteri…
