Small-bowel diverticulosis:imaging findings and review of three cases.

Complicated small-bowel diverticulosis is a rather uncommon cause of upper abdominal pain. It may lead to symptoms presenting with an acute onset or to chronic and nonspecific complaints. As the presentation is often similar to other pathologies (acute appendicitis, pancreatitis, or acute cholecystis) and in many cases diagnosis is made on basis of surgical findings, careful analysis of the imaging landmarks may be warranted to aid in the early stages of detection. In this report, we present clinical and morphological findings in three patients where small-bowel diverticulitis was surgically proven. The relevant literature is reviewed, and typical imaging properties are discussed.

Jaw fixation as the key to diagnosis of fibrodysplasia ossificans progressiva.

Fibrodysplasia ossificans progressiva is a very rare and disabling hereditary disorder of connective tissue characterised by symmetric congenital anomalies of the great toes and thumbs and by progressive heterotopic ossification of tendons, ligaments, fasciae and striated muscles. In this case we report a 17-year-old boy who presented with a painful swelling of the right mandibula with trismus. Multiple heterotopic soft tissue calcifications, severe scoliosis and typical anomalies of toes and thumbs on the radiographs were pathognomonic for fibrodysplasia ossificans progressiva.
