Abstract
Adult-type ovarian granulosa cell tumors (AGCTs) are very rare tumors that account for <5% of all ovarian carcinomas. AGCTs have low malignancy potential and rarely metastasize 5-30 years after the initial diagnosis. Because time has passed from the first surgery and because recurrence develops in various locations, the differential diagnosis is difficult. In particular, tumors developing in the greater omentum are encountered rarely, and it is necessary to carefully consider the differential diagnosis, including primary and secondary neoplasms. Although CT is useful to detect omental tumors, the diagnosis requires invasive procedures. We report a case of AGCT recurrence in the greater omentum that was resected during laparoscopic cholecystectomy. A patient visited our hospital with right-sided abdominal pain. The CT revealed gallbladder stones, a ureteral stone, and a right abdominal mass. The diagnosis of the abdominal tumor was difficult on the basis of blood biochemical testing, gastrointestinal endoscopy, or image inspection. Although the patient underwent several previous surgeries and there were no findings of malignancy with positron emission tomography, we chose to resect the tumor for combined diagnosis and treatment during laparoscopic cholecystectomy. Intraoperative findings showed that the tumor originated from the greater omentum, and the tumor was diagnosed as AGCT recurrence by pathology. A recurrence of AGCT in the greater omentum is very rare, and laparoscopic surgery was safe and useful for resection, in our case.

Abstract
PURPOSE To demonstrate the advantages of CT-guided biopsy of subdiaphragmatic small renal nodule with the coaxial technique using MPR images. METHODS The study included retrospectively 12 patients who underwent CT-guided biopsy with 18 G needle of subdiaphragmatic small renal nodule (<15 mm) suspected. Histology reports have been the reference standard. RESULTS The histology was diagnostic in 12 biopsies (100%): out of 10 neoplastic nodule (83.3%), 8 were malignant (80%) and 2 were benign (20%); 2 out of 12 were non-neoplastic (16.6%). No procedural complications were observed (0%). CONCLUSIONS By using MPR images there is an effective improvement during coaxial CT-guided biopsy of subdiaphragmatic small renal nodule difficult to reach and to reduce the complication as pneumothorax.
