The authors' experience with splenic hydatidosis is presented. Sixteen cases, representing 3% of the hydatidosis treated surgically in our center, are reviewed. Pain in the left upper quadrant, splenomegaly and calcifications detected by simple abdominal radiology are the most suggestive indications. The definitive diagnosis is based on abdominal echography and CT scan, which have the greatest sensitivity and specificity. The treatment should be surgical, attempting to preserve as much splenic tissue as possible, although in our experience, it is infrequent that conservative treatment can be used due to massive involvement of the spleen.
