Liver and Additional Body Cyst Cases: Providing Radiological and Clinical Perspectives

Hydatid disease, a parasitic infection caused by Echinococcus granulosus or Echinococcus multilocularis, has been the focus of a recent case series involving nine patients. The disease, which primarily affects the liver but can also involve other organs, was diagnosed in these patients through a combination of clinical symptoms, imaging techniques, and serological tests.

The cases presented a range of symptoms and affected various organs. For instance, Case 5 involved a 58-year-old male shepherd who had a 5-year history of abdominal distension and a 2-month history of fever and vomiting. He was diagnosed with disseminated hydatid disease involving multiple organs. In contrast, Case 3 involved a 32-year-old male with a 6-month history of persistent right-flank pain, who was diagnosed with an isolated renal hydatid cyst.

Imaging findings played a crucial role in the diagnosis of these cases. Ultrasonography was widely used for identifying cystic lesions, particularly hepatic hydatid cysts, while Computed Tomography (CT) imaging was preferred for identifying cyst calcifications, internal septations, and complications, such as rupture or infection. The characteristic "double-wall sign" on CT is highly specific for hydatid cysts.

MRI was found to be useful in assessing soft tissue involvement and distinguishing hydatid cysts from other cystic lesions. In Case 2, the largest cysts were located in segments VII and VIII of the liver, and the imaging findings were consistent with those of multilocular hepatic hydatid cysts. In Case 4, another cystic lesion containing multiple daughter cysts and hydatid sand was observed in the peritoneum.

The cases included cystic lesions in the liver (7 patients), spleen (3 patients), kidney (2 patients), and peritoneum (1 patient). Serological tests can detect antibodies against E. coli antigens, but sensitivity can vary depending on the location and stage of the cyst.

Early diagnosis using advanced imaging techniques and a multidisciplinary approach is critical for effective management and prevention of complications. Management strategies varied from surgical excision to medical therapy with albendazole. In Case 5, extensive multiloculated cystic lesions were found involving the liver, spleen, and peritoneal cavity. A hypodense lesion with calcification was observed in liver segment VI in this case.

Regions particularly affected by hydatid disease are typically those with agriculture and close human-animal contact, such as parts of the Middle East, Central Asia, South America, and the Mediterranean basin. This case series underscores the importance of awareness and early diagnosis in managing this disease, especially in regions where it is prevalent.
