case_images: Absorptiometry (DEXA) scan found normal values for age at the hip, with Z-scores of - 1.2 SD at the femoral neck and - 1.0 DS at the total hip, but a low Z-score of - 2.8 SD at the lumbar spine, with an osteoporotic T-score value of - 3.0 SD at this site, though not really interpretable due to the lumbar fractures. A bone scan highlighted diffuse hyperfixation foci corresponding to non-consolidated fractures of the ribs, the sacrum and all the dorsal and lumbar vertebrae (Fig. 1).
case_images: The tumor on the PET-CT and at the ultrasound scan. A Nodular subcutaneous hypermetabolic (max SUV 3) lesion in the left thigh. B Subcutaneous hypoechogenous lesion at the ultrasound measuring 17 x 8 x 14mm, vascularized with arterial and venous flow with Doppler

case_images: A positron emission tomography and computed tomography (PET-CT 18-FDG) showed the recent vertebral and pelvic fractures, and it identified multiple recent rib fractures; moreover, it highlighted the presence of a 11 x 15 mm hypermetabolic subcutaneous lesion in the proximal left upper thigh, which was later described as an arteriovenous malformation on ultrasound (Fig. 2).
