RESUMO
Hydatid disease is the most common human disease caused by helminths, but primary skeletal involvement is uncommon. Diagnosis is usually obtained late after considerable extension, half of which concerns the spine. The dissemination mode leads to local malignancy with severe prognosis. Medical imaging is essential. Plain x-ray findings are polymorphous and nonspecific, but computed tomography and magnetic resonance imaging are particularly useful for exhaustive pretherapeutic assessment of extension and for patient follow-up.

Mycetoma remains a common pathology in tropical areas. Diagnosis, based on mycology and pathology is still frequently late and treatment often leaves severe functional disorders. Medical imaging is indispensable to evaluate disease spread to bone tissue. Plain radiograms usually show cortical erosion, defects with sclerosing margins, and bone thickening. CT is the most sensitive technique to detect bony involvement. CT and MR imaging, when available, are the most accurate techniques for determining disease extension in both bones and soft tissues.

Bone and joint localizations of treponematosis vary greatly although there are many common features. Osteal and periosteal lesions are common. We report radiographic descriptions of bone and joint treponematosis, which must not go unrecognized due to the increasing incidence of these diseases.

A case of an adult intussusception secondary to a fibroid polyp of the terminal ileum is reported. Adult intussusceptions are observed rarely, usually caused by an organic lesion. The preoperative diagnosis is based on US patterns, target aspect and sandwich sign.
