Hydatid disease: Biology, pathology, imaging and classification

Gluteal region musculoskeletal hydatid cyst: Case report and review of literature

“…Computed tomography or ultrasound-guided needle biopsies also are helpful in diagnosis [25], although some authors do not recommend it because of the risk of cyst rupture and anaphylactic reaction could occur [26]. Lewell [27] classified hydatid cysts into three types according to their imaging appearance. Type I is a fluid filled cyst-like structure, which may proceed to a Type II lesion if daughter cysts and/or matrix develop.…”

Hydatid Disease: Current Status and Recent Advances

“…The metacestode develops into a unilocular fluid-filled cyst ( Figure 2). 2,10,13 E granulosus cysts following primary infection may inhabit any anatomic site. The two most common organs involved are liver (65%) and lungs (25%).…”

“…The selection of these tools depend upon the organ to be imaged, the status of the cyst (intact, ruptured or infected) and adjacent structures which need to be assessed. 2,18,29 Plain radiography has a role in lung and bone cysts. A plain film of chest shows intact cyst as sharply demarcated round-to-oval homogenous mass of variable size.…”

A Case of Primary Peritoneal Hydatidosis

“…Ultrasonography is the first line of screening and leads to diagnosis in more than 95% of cases [6]. CT scan gives better evaluation of hydatid cysts.…”
