Type CE2 disease in a 17-year-old Uygur female patient.

<p>The patient experienced left lower back pain for three years and pain aggravation for two weeks with nausea. She had no history of exposure to sheep or dogs. Physical examination showed percussion tenderness over the left kidney region. A CT scan (A) showed connection of a CE cyst with the renal pelvis and an enhanced image indicated a thick-walled cystic lesion at the middle outer edge of the left kidney (6.7 cm×3.8 cm) (B). The boundary was clear, soft tissue septum, and multiple daughter vesicles and wall calcifications were also evident. The lesion communicated with the middle calyx and showed no enhancement. The left renal pelvis and calyx were dilated, and there was a patchy shadow of calcification.
