    Abstract:
    AIM: To report our experience with four cases of isolated hydatid disease of the spleen studied by spiral Computed Tomography (CT) and to review the literature with special attention to the differential diagnosis with other focal lesions of the spleen. MATERIALS AND METHODS: The spiral CT images and clinical records of four patients (1 man, 3 women; age range 26-45 yrs) affected by isolated hydatid disease of the spleen were retrospectively evaluated. None of the patients had a history of hydatid disease. All the patients were evaluated by plain and enhanced spiral CT of the abdomen. All patients underwent preoperative chest X-ray and surgery; all surgical specimens were studied by histology. RESULTS: Spiral CT depicted all the hydatid lesions of the spleen. It showed the location, size, low density of their content without enhancement after iv contrast medium injection, the possible presence of daughter cysts, the appearance of the wall with calcifications, and excluded the presence of complications. The preoperative chest X-ray was negative for focal pulmonary lesions in all cases. Pathology confirmed the diagnosis of hydatid disease in all cases. CONCLUSIONS: According to our results and to the literature, spiral CT plays an important role in the pre-surgical evaluation of patients with hydatid disease of the spleen, and provides useful information for differentiating the disease from other isolated cyst-like lesions of the spleen.
