Chronic systemic problems included diabetes mellitus II, gastric reflux, obesity, obstructive pulmonary disease, congestive heart failure, and groin lymphedema. Physical examination showed an obese man (BMI 40.1) who moved with difficulty and had exertional dyspnea. Penile and left scrotal skin were swollen. A large, soft, nontender mass filled his left inguinal canal and scrotum. This could be partially reduced with the patient supine. Ultrasound examination of his groin showed groin skin edema and a soft tissue mass in the scrotum. Computerized tomography showed a six by eight centimeter fatcontaining hernia extending into the scrotum. The left kidney was ptotic. (Figure 1, 2) Because the hernia was very broad-based, its contents did not seem to be at risk for strangulation. For this reason and the patient s high operative risk, surgical therapy was not recommended. DISCUSSION A hernia is the protrusion of an organ or structure through an abnormal opening. An indirect inguinal hernia does not always have a sac, once considered a fundamental feature of that disorder. A lipoma is a discrete, encapsulated portion of fat and can occasionally be found in the spermatic cord. However, most so-called cord lipomas are extrusions of retroperitoneal fat alongside the cord. Thus they are hernias. [1, 2] Such fatty cord masses are common. They were noted in thirty-three percent of a clinical study and seventy-five percent of a cadaver study. [2, 3] They can be large and cause symptoms. On physical examination, they can be confused with a saccular hernia and are rarely diagnosed preoperatively. Bondevik presented a case of massive prolapse of retroperitoneal fat and ureter into the scrotum. After considering various terms, the author dubbed this a fatty hernia. It is rare, his case being the fifth reported in four patients. [1] Prolapse of Page 3 of 6

All reported cases have been in obese patients. Renal ptosis is characteristic. Ureteral herniation can be caused by gravitational pull of the attached mass of fat [4]. When feasible, treatment consists of excision or reduction of herniated fat and closure of the abdominal inguinal ring defect. The potential for ureteral injury must be considered. CONCLUSION Fatty hernias are rare. Computerized tomography reliably demonstrates their anatomy. If surgical treatment is chosen, the anatomic course of the ureter should be delineated preoperatively.
