Figure 2.

This figure shows sacral hydatid disease in a middle-aged man with chronic vague pelvic pain. A. Anteroposterior (AP) pelvic radiograph shows a massive destructive bone lesion in the lower segments of the sacrum without dystrophic calcification (asterisk) with faintly visible adjacent soft tissue mass (arrow). B. Coronal non-contrast enhanced pelvic CT shows a soft tissue mass with adjacent bone destruction which extends through the right sacral foramen into the spinal canal (asterisk). This figure was obtained from a patient who was admitted to the authors’ institution and was not previously published.
