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.

Figure 14: A 44-year-old-man with type II hydatid cyst of the left kidney. After albendazole therapy, detached germinal membranes are seen within the cyst as low signal intensity linear structures on coronal T2-weighted spin-echo MRI (white arrow).

Mentions: Renal HD is rare (3% of case), usually solitary and located in the cortex (2). These patients may present with a flank mass, dysuria, pyuria, hematuria, persistent fever, renal stones, hypertension or renal colic (10). Hydatiduria can occur after rupture of the cyst into the collecting system (5). Any form of HC can be seen in renal HD (Fig. 14) (2, 3, 10). Mural calcification and daughter cysts often coexistent. These findings are helpful in the differential diagnosis of HCs from a simple renal cyst, necrotic renal cell carcinoma, renal abscess and infected cysts, but it sometimes can be difficult to differentiate HC from necrotic renal cell carcinoma since calcifications may be encountered in both lesions (2, 10).
