Clinical Analysis of 58 Patients with Adrenal Myelolipoma

Abstract：Objective To explore diagnosis,differential diagnosis and surgical treatment of adrenal myeloli-poma. Methods 58 patients with adrenal myelolipoma from Oct. 2004 to Aug. 2014 were analyzed,including 32 males and 26 females,whose ages were between 18 and 74 years old with average age of 34 years. Tumor diameters of 33 ca-ses were smaller than 5 cm,21 cases were between 5 and 10 cm,4 cases were bigger than 10 cm. The minimum diame-ter was 1. 8 cm with maximum 16 cm. Adrenal cortex hormone test,adrenal medulla hormone test,abdominal ultra-sound and CT examination were performed in 58 patients. MRI examination was performed in 14 cases. Surgery and postoperative pathological examination were performed in all patients. 51 cases underwent retroperitoneoscopic renal tumor resection and 7 cases underwent open surgery. Results There were no significant differences in adrenal cortex hormone and adrenal medulla hormone. 58 cases were all adrenal myelolipoma by CT examination and pathological di-agnosis after operation. All adrenal myelolipomas were fully resected. Most of the patients had relative symptoms which were disappeared after operation. 42 patients were followed up for 3 months to 7 years with no recurrence. Conclusion The preoperative diagnosis and differential diagnosis of adrenal myelolipoma mainly depend on imaging examina-tion,adrenal cortex hormone test and adrenal medulla hormone test. Retroperitoneoscopic renal tumor resection is the first choice for patients with operative indications.
