Skeletal scintigraphy is one of the most commonly requested nuclear medicine tests. Extraosseous conditions including myositis have been described with this imaging modality. A 75-year-old febrile gentleman was initially suspected to have right lower leg cellulitis. A lower limb Doppler ultrasound revealed fi ndings suggestive of myositis without focal abscess or collection in the right pretibial region. Subsequently, SPECT/CT bone scintigraphy demonstrated abnormal uptake in the pretibial soft tissue as well as in the left piriformis muscle, consistent with multifocal myositis. Clinically, the underlying aetiology was felt to be infectious and the patient improved with antibiotics. This case helps illustrate the usefulness of SPECT/CT bone scintigraphy in demonstrating extraosseous lesions and in excluding common conditions, such as fractures and osteomyelitis.
