Lanthanum carbonate hydrate is a nonaluminum, noncalcium phosphate binder containing lanthanum (La). It is effective in decreasing the serum phosphate level in patients on dialysis. ⋯ The CT images were difficult to evaluate because of strong beam hardening artifacts, and differentiation from foreign body aspiration was required. We report here our experience and a discussion of the characteristics of this artifact.

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%.

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.

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.
