Comparative Study
High prevalence of vertebral artery tortuosity of Loeys-Dietz syndrome in comparison with Marfan syndrome.
Loeys-Dietz syndrome (LDS) is a connective tissue disease caused by mutations in the genes encoding the transforming growth factor-beta receptor (TGFBR). LDS is associated with aneurysms or dissections of the aorta similar to Marfan syndrome (MFS) as well as arterial tortuosity and aneurysms in the peripheral arteries. The purpose of this study was to evaluate the arterial diseases of LDS to differentiate it from MFS. ⋯ The VAT was highly prevalent among LDS patients. Thus, the presence of VAT has the potential to differentiate LDS from MFS.

We report a case of a 38-year-old man affected by the human immunodeficiency virus (HIV) with a diagnosis of Castleman's disease, plasmablastic type human herpes virus 8 infection, and Kaposi sarcoma based on a histological examination of one cervical lymph node biopsy. The patient underwent (18)F-2-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT). (18)F-FDG-PET/ CT seems to be a valuable tool in patients with HIV-associated Castleman's disease and Kaposi sarcoma. It allows accurate staging and identifies more sites of disease than conventional CT.

True tracheal bronchus (TTB) is a rare anomaly in which a lobar or segmental ectopic bronchus arises from the trachea. We examined the frequency and multidetector computed tomography (MDCT) appearances of TTB. ⋯ TTB was identified by MDCT with an incidence of 0.31%.

We compared the diagnostic accuracy of fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) and PET/magnetic resonance imaging (MRI) fusion images for gynecological malignancies. ⋯ PET/T2WI fusion images are superior for the detection and localization of gynecological malignancies.

Blunt gallbladder injury is rare, and bleeding from the cystic artery due to blunt trauma is even rarer. We report herein a case of extraluminal bleeding of the gallbladder in a patient following blunt abdominal trauma. ⋯ Abdominal digital subtraction angiography revealed pseudoaneurysm originating from a branch of the cystic artery. Successful treatment was achieved using selective transcatheter embolization, and cholecystectomy was not required.
