Abstract We report the case of a 16-year-old male patientpresenting with several mass lesions on the left side of hisneck that had been there for weeks. Whole-body 18Ffluorodeoxyglucosepositron emission tomography and computedtomography (18F FDGPET-CT) revealedmultiple focalareas of increased uptake of fluorodeoxyglucose (FDG) on theleft side of the neck, left supraclavicular fossa, left axilla, andmediastinum, simulating the imaging findings of Hodgkin’slymphoma. Subsequent incisional biopsy of lymph nodes inthe left supraclavicular fossa with histologic examination confirmedthe diagnosis of Kimura disease. The differential diagnosesshould include Kimura disease when evaluating regionalor generalized lymphadenopathy seen on 18F FDGPET-CTbecause it also may show prominent uptake of FDG.

The radiological appearance of diffuse discrete pulmonary nodules associated with cryptogenic organizing pneumonia (COP) has been rarely described. We describe a case of COP in 49-year-old woman with acute myeloid leukemia who developed diffuse pulmonary nodules during the second course of induction chemotherapy. The clinical status of the patient and imaging findings suggested the presence of a pulmonary metastasis or infectious disease. A video-assisted thoracoscopic lung biopsy resulted in the unexpected diagnosis of COP as an isolated entity. Steroid therapy led to dramatic improvement of the clinical symptoms and the pulmonary lesions.
