We report a very rare case of retroperitoneal angiomyolipoma with rapidly progressing intracystic hemorrhage and lymph node involvement in a 34-year-old female. She was admitted to our hospital complaining of a severe pain in the lower abdominal region, followed by oligemic shock. Abdominal enhanced computed tomography (CT) demonstrated a retroperitoneal giant cyst with intracystic hematoma, which displaced the left kidney anteriorly. Because transarterial embolization was unsuccessful transabdominal left nephrectomy combined with excision of the giant cyst was performed to keep the continuing hemorrhage under control. Simultaneously, a swollen paraaortic lymph node was also resected. The histologic findings of resected tissue and lymph node were retroperitoneal angiomyolipoma with lymph node involvement. The patient is being followed up at our hospital without recurrence.
