Hydatid disease is endemic in many parts of the world. It may develop in almost any part of the body. The location is mostly hepatic (75%) and pulmonary (15%), and only 10% occur in the rest of the body. In this article, the various imaging findings of hydatid cysts in unusual localizations are reviewed, based on our experience. Findings in brain, cavernous sinus, submandibular gland, thyroid gland, heart, pleura, chest wall, retrocrural tissue, kidney, spleen, pancreas, peritoneal cavity and inguinal canal, breast, bone and soft tissue are discussed.

CT-marking and fluoroscopy-guided intraarticular corticosteroid instillation in the sacroiliac joints may be regarded as an effective therapy. This technique was useful, rapid and safe.

The multiplanar capabilities of MRI are invaluable to evaluate spreading and margins of an endometrial mass, and the 3D dynamic MR techniques offer the advantages of increased coverage and high spatial resolution. Three dimensional dynamic MR imaging may be recommended in the especially postmenopausal cases before performing potentially curative treatments.
