Alport syndrome is often characterized by renal dysfunction and hearing loss due to abnormalities in type IV collagen production. In this study, we report a rare case of recurrent aortic dissections that developed in a young patient with Alport syndrome over a short period. We discuss the associations between Alport syndrome and aortic dissection with a literature review and emphasize the need for regular follow-up of patients with Alport syndrome for early detection of aortic disease.

Infective endocarditis (IE) due to is rare. Given that cases of IE complicated with a left ventricular pseudoaneurysm (LVP) caused by have not been reported thus far, here we report a case of IE complicated with an LVP caused by . An 83-year-old woman was admitted to our hospital for urinary tract infection, and was detected in blood cultures.

We present a case of superior mesenteric venous thrombosis (SMVT) treated successfully with thrombectomy without bowel resection. A 73-year-old female was referred to our hospital with complaints of stomach ache. The patient was diagnosed with SMVT with impending bowel necrosis and underwent an emergency operation, after computed tomography (CT) revealed a thrombus in the superior mesenteric vein (SMV) extending to the splenic vein, ascites, and extremely edematous intestines.

Constrictive pericarditis (CP) is an uncommon disease characterized by clinical signs of right-sided heart failure subsequent to loss of pericardial compliance. Although pericardiectomy is the accepted treatment for improving cardiac hemodynamics in CP, some patients fail to improve after pericardiectomy. We herein report a case of CP that showed some physical and hemodynamic features with a constrictive pattern that persisted despite the improvement in heart failure symptoms after pericardiectomy.

Symptomatic carotid dissection, secondary to surgical repair of Stanford type A acute aortic dissection (AAD), requires prompt intervention. A 56-year-old man who underwent total arch replacement with frozen elephant trunk for AAD presented with left hemiplegia and unilateral spatial neglect 16 h after the surgery. Cerebral computed tomography (CT) revealed no fresh lesions, and CT angiography showed severe bilateral carotid dissection.

Purpose: The purpose of this study was to assess phase shift due to the inversion recovery process and the chemical shift effect in inversion recovery prepared gradient-echo magnetic resonance imaging.

Materials And Methods: The signal intensities of three phantoms, composed of physiologic saline solution with Gd-DTPA, olive oil, and fat emulsion, were measured on a 1.5 Tesla unit.

This report documents a case of intravascular lymphoma (IVL) with increased regional cerebral blood flow (rCBF) disclosed at I-123 IMP single-photon emission CT (IMP-SPECT). A 73-year-old woman with IVL had high rCBF disclosed by IMP-SPECT before chemotherapy; rCBF was normal after one course of CHOP (cyclophophamide, vincristine, doxorubicin, and prednisone) chemotherapy. During her clinical course, she had an episode in which she showed increased rCBF in the left cerebral hemisphere at IMP-SPECT performed immediately after the recovery from the right hemiparesis.
