Background: Various abdominal vessels can compress the adjacent structures or in turn can get compressed by them. Most of these compression syndromes present with non-specific symptoms. Unlike the common causes of acute abdomen, the various vascular compression syndromes have bizarre clinical presentations and subtle imaging findings, which can easily be missed by the physicians as well as the radiologists. Main body of the abstract: This is a retrospective study which was done for a period of 3 years from April 2015 to April 2018 using a 64-slice CT scanner. Among 2412 cases that came for evaluation, 114 patients were diagnosed to have one of the various vascular compression syndromes. These 114 cases were further managed either conservatively or surgically depending on the pathology and the severity of the compression. The syndromes discussed in this article include median arcuate ligament syndrome (29 cases), superior mesenteric artery syndrome (23 cases), portal biliopathy (3 cases), nutcracker syndrome (6 cases), pelvi-ureteric junction obstruction due to crossing of vessels (8 cases), and retrocaval ureter and May-Thurner syndrome (45 cases). Conclusions: The primary goal of this article is to reinforce the knowledge of the radiologists of the various vascular compression syndromes and to make them possess a high degree of vigilance to detect them. This article elaborates the imaging findings of these syndromes and the role of multidetector CT angiography in diagnosing them.
Fascioliasis is a re-emerging food-borne parasitic zoonosis which presents with nonspecific clinical symptoms. Definitive diagnosis requires demonstration of parasitic ova in stool which may often be elusive. Imaging plays a crucial role in raising the possibility of this diagnosis early in the disease course. Contrast-Enhanced Computed Tomography (CECT) of the abdomen was performed in a 44-year-old male with fever, right upper quadrant pain and dyspepsia. The patient later underwent an ultrasound-guided biopsy of liver lesions. The stool examination for ova was negative. Biopsy of the liver lesions showed ill-defined granulomas. Imaging plays a crucial role in establishing the early diagnosis of hepatic fascioliasis especially in nonendemic regions where the clinical suspicion for this diagnosis is low. This article places emphasis on the description of typical imaging features of this condition and the usage of additional investigative/testing techniques recommended by the Center for Disease Control and Prevention (CDC).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
