Isolated spontaneous dissection of the celiac trunk in a patient with bicuspid aortic valve

Isolated spontaneous dissection of celiac trunk is a rare entity. The spontaneous dissection of the visceral artery occurs without aortic dissection. The most consistent presenting symptom is acute onset abdominal pain. Complications consist of ischemia, aneurysm formation, and rupture. We report an exceptional case of an isolated spontaneous dissection of the celiac trunk which occurred in a 49 year old male with a previously undiagnosed bicuspid aortic valve (BAV). We also describe the classical appearance in different imaging modalities with a particular emphasis on multidetector computed tomography, and discuss the clinical manifestation and its relationship to BAV

Isolated periaortitis: Clinical and imaging characteristics

Chronic periaortitis includes a variety of conditions that have similar clinical and histopathological findings, and thus probably represents different manifestations of the same disease: idiopathic retroperitoneal fibrosis, perianeurysmal retroperitoneal fibrosis, and inflammatory abdominal aortic aneurysms. We describe the clinical and imaging characteristics of the nonaneurysmal form of chronic periaortitis, recognized as isolated periaortitis, in an adult male patient presented with low back pain

Small intestine perforation due to metastatic uterine cervix interdigitating dendritic cell sarcoma: a rare manifestation of a rare disease

Interdigitating Dendritic Cell Sarcoma (IDCS) is an infrequent dendritic cell tumor which mainly affects the lymphatic system. Intestinal metastasis from uterine IDCS is extremely rare. Here we report a case of a 76-year-old female presenting with vaginal bleeding and acute abdomen. The final diagnosis revealed a small bowel perforation due to metastatic involvement from uterine cervix IDCS. In this paper, we report the clinical manifestation, computed tomography and histopathological findings helpful for the accurate diagnosis of this rare tumor

Coronary CT Angiography Findings in Patients with Ambiguous Left Main Coronary Artery Disease

Left main coronary artery (LMCA) stenosis is a high risk subset of coronary artery disease; however, its occurrence may be misjudged by coronary angiography. Coronary CT angiography (CCTA) was performed on 5 patients with clinically highly suspicious and angiographically borderline LMCA disease (ostial: 3 patients, mid: 1 patient and distal: 1 patient). A cross-sectional CCTA image was used to calculate the diameter stenosis. The quantitative coronary angiography (QCA) reference diameter (RD) correlated well with CCTA RD in all 5 patients. However, the lesion site minimal lumen diameter (MLD) by QCA correlated less well with that obtained by CCTA. The grade of stenosis measured by CCTA was significantly lower than that measured by QCA. Morphologically, three patients had LMCA ostial angulation (with minimal atheromatous changes), one patient had a biconcave configuration of the LMCA (with normal vessel wall) and one other had a tapering-morphology of the LMCA (with minimal atheromatous changes). In conclusion, CCTA may have a complementary diagnostic role in patients with angiographically ambiguous or inconclusive LMCA lesions and therefore it should be considered in the assessment of selected patients before they undergo coronary bypass surgery. In order to validate CCTA for main stem stenosis a proper gold standard, such as IVUS, is required
