Bottom Line: Unusual sites for this disease can cause diagnostic problems.This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum.Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

ABSTRACT
Hydatid disease (HD) is an endemic illness in many countries, and it poses an important public health problem that's influenced by peoples' socioeconomic status and migration that spreads this disease. Although rare, it may occur in any organ or tissue. The most common site is the liver (59-75%), followed in frequency by lung (27%), kidney (3%), bone (1-4%) and brain (1-2%). Other sites such as the heart, spleen, pancreas and muscles are very rarely affected. Unusual sites for this disease can cause diagnostic problems. This pictorial essay illustrates various radiological findings of HD in the liver, spleen, kidney, pancreas, peritoneal cavity, omentum, adrenal, ovary, lung, mediastinum and retroperitoneum. Familiarity with the imaging findings of HD may be helpful in making an accurate diagnosis and preventing potential complications.

Type II hydatid cyst in a 36-year-old man. Contrast-enhanced axial CT scan of the upper abdomen demonstrates cystic lesion with peripheral daughter cysts and wall calcification in the left lobe of the liver. Note the daughter cysts have a lower attenuation value than the mother cyst (arrows).

Figure 2: Type II hydatid cyst in a 36-year-old man. Contrast-enhanced axial CT scan of the upper abdomen demonstrates cystic lesion with peripheral daughter cysts and wall calcification in the left lobe of the liver. Note the daughter cysts have a lower attenuation value than the mother cyst (arrows).

Mentions: For type II HCs, many daughter cysts and/or matrix develop within the parent cyst with or without cyst wall calcification (Fig. 2) (1). Daughter cysts, indicating viability, have a lower attenuation value than that of mother cysts on CT scans (Fig. 2). On MRI, daughter cysts may appear slightly hypointense or isointense relative to the maternal matrix on the T1-weighted images and hyperintense on the T2-weighted images. When present, floating membranes are seen as low signal intensity linear structures within the cyst on both the T1- and T2-weighted images (2, 3, 8).
