ABSTRACT
We previously reported the 68Ga-labeled prostate-specific membrane antigen (PSMA)-11 and 99mTc-dimercaptosuccinic acid (DMSA) images of the first patient in our prospective research comparing renal 68Ga-PSMA-11 PET with 99mTc-DMSA scanning in adults with pyelonephritis. Here, we present the renal cortical 68Ga-PSMA-11 PET and 99mTc-DMSA images of our second patient, who had chronic recurring pyelonephritis and demonstrated renal parenchymal defects secondary to scarring in the kidney.

Kikuchi-Fujimoto disease, known as Kikuchi disease, is a rare benign and self-limiting disorder that typically affects the regional cervical lymph nodes. Generalized lymphadenopathy and extranodal involvement are rare. We report a rare case of a 19-year-old female with a history of persistent fever, nausea, and debilitating malaise. Fluorine-18-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) revealed multiple hypermetabolic generalized lymph nodes in the cervical, mediastinum, axillary, abdomen and pelvic regions with diffuse spleen, diffuse thyroid gland, and focal parotid involvement, bilaterally. In addition, subcutaneous lesions were noted in the left upper paraspinal and occipital regions. An excisional lymph node biopsy guided by 18F-FDG PET/CT revealed the patient's diagnosis as Kikuchi syndrome.
