RESUMO
We describe the F-FDG PET/CT findings in a rare case of mesenteric panniculitis caused by systemic lupus. A previous CT had raised suspicion of a space-occupying lesion in the left hypochondrium in a context of aspecific constitutional symptoms and inflammatory parameters. The diagnosis of panniculitis was confirmed at laparoscopic biopsy directed by the PET findings. Follow-up F-FDG PET/CT after 1 month of corticosteroid therapy showed complete disappearance of the abdominal hypermetabolic foci.

We describe the bone scan and single-photon emission computed tomography/computed tomography findings in calcific tendinitis of the gluteus maximus and discuss its pathophysiology. Although this tendinopathy is mostly self-limiting, awareness of this disease is important for 2 reasons. First, it may explain acute hip symptoms in patients in the resorptive phase of the calcifications. Second, it should be considered as a differential diagnosis for bone scan hot spots in the vicinity of the gluteus maximus tendon and for cortical erosion seen in that region on X-rays or CT.
