Case ReportsCold exposure-induced rhabdomyolysis demonstrated by bone scintigraphy.
This report describes a case of acute renal failure due to rhabdomyolysis that developed after prolonged exposure to cold. A 47-year-old man visited a mountain during winter wearing only casual clothes and became lost at temperatures below freezing for 8 hours. ⋯ The serum blood urea nitrogen, creatinine, creatinine kinase, and myoglobin levels were elevated. Bone scintigraphy on the second day revealed increased activity in the superficial muscle groups in the abdomen, back, buttock, thighs, legs, and arms, which was compatible with rhabdomyolysis.

Case ReportsFDG uptake in abdominal mesh implant on FDG PET/CT.
A 50-year-old man with peritoneal angiosarcoma underwent total tumor excision along with removal of the total right rectus and medial part of the left rectus muscles 1 year earlier. F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) was performed for suspected recurrence. ⋯ The patient had a history of a dual mesh implant, which consists of polypropylene and polyvinylidene fluoride for the reinforcement of the abdominal wall during the operation. PET/CT fusion image demonstrated that the finding was due to the dual mesh implant in the anterior abdominal wall most likely representing a foreign body reaction.

Case ReportsHashimoto thyroiditis and Takayasu aortitis: visualization of the thyroid gland and ring appearance of the mediastinum on F-18-FDG PET.
A woman with Hashimoto thyroiditis, treated with levothyroxine for 4 years, complained of chest pain that radiated to the neck and had progressively worsened for 2 months. CT of the chest showed circumferential thickening of the ascending aorta and aortic arch, compatible with Takayasu arteritis. She underwent F-18 FDG PET imaging, which revealed an abnormal thyroid gland and a ring-like appearance of the mediastinum.
