A 53-year-old woman was found to have a soft tissue mass in the right lower lung lobe on chest CT, raising suspicion of lung cancer. For staging, 18F-FDG PET/CT was performed, which demonstrated intense tracer uptake in the mass (SUVmax, 14.6). Subsequently, surgical excision was undertaken, and histopathological examination of the resected specimen confirmed the diagnosis of a schwannoma.

Solitary axillary lymph node metastasis from ovarian cancer is rare. A 74-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for ovarian cancer 2 years ago presented to our hospital with enlarged axillary lymph node. 18F-FDG PET/CT revealed left axillary lymphadenopathy with an SUVmax of 8.

Neoplastic meningitis, also known as leptomeningeal metastases, is a rare clinical entity seen in less than 1%-2% of primary nervous system tumors. Diagnosis of leptomeningeal metastases is difficult and is achieved by cytologic evidence of malignant cells in cerebrospinal fluid, or demonstration of radiologic abnormality. 18F-FDG PET/CT can detect leptomeningeal metastases before anatomical changes.

We present the case of a 60-year-old man admitted to the hospital presenting with high FUO (fever of unknown origin), strong headache, face erythematous-desquamative cutaneous lesions, long history of abdominal pain, and diffuse myalgia. He was also previously treated with immunosuppressants and currently managed with corticosteroids for a seronegative rheumatic disease. Given the immunocompromised state, an infective etiology was suspected.

From the Department of Nuclear Medicine, Central People's Hospital of Zhanjiang, Zhanjiang, China.
Subcutaneous nodules and masses as the primary manifestation of diffuse large B-cell lymphoma are exceedingly rare. We present 18F-FDG PET/CT findings of multiple hypermetabolic nodules and masses distributed throughout the body, creating a characteristic "leopard man" appearance on the MIP image, in a 65-year-old man. An excisional biopsy of the right thigh mass confirmed the diagnosis of diffuse large B-cell lymphoma.

From the Key Laboratory of Carcinogenesis and Translational Research (Ministry of Education/Beijing), NMPA Key Laboratory for Research and Evaluation of Radiopharmaceuticals (National Medical Products Administration), Department of Nuclear Medicine; Peking University Cancer Hospital and Institute, Beijing, China.
Purpose: The aim of this study was to compare Al18F-NOTA-HER2-BCH and 18F-FDG for detecting nodal metastases in patients with HER2-positive breast cancer on PET/CT.
Patients And Methods: In this retrospective study, 62 participants with HER2-positive breast cancer underwent both Al18F-NOTA-HER2-BCH and 18F-FDG PET/CT. Participants were pathologically confirmed as HER2-positive (IHC 3+ or IHC 2+ with gene amplification on FISH).
