Retroperitoneal leiomyomas with intratumoral bleeding: Presentation with multiple-organ dysfunction syndrome - A case report.

BACKGROUND

Retroperitoneal leiomyomas are rare benign smooth muscle tumours. Diagnosing these tumours is often challenging due to their unique growth site and nonspecific clinical manifestations. There are a few reports of leiomyomas with intratumoral bleeding.

CASE PRESENTATION: A patient with a giant retroperitoneal leiomyoma presented with multiple-organ dysfunction syndrome accompanied by a progressive decrease in haemoglobin. Computed tomography (CT) revealed two cystic tumours in the abdominal cavity. The patient was underwent transabdominal retroperitoneal tumour resection. During surgery, we found two retroperitoneal tumours-one contained approximately 9000 mL of dark red fluid and the other contained 1000 mL of light brown fluid. She has recovered well without any complications.

CONCLUSIONS

There have been only a few reports of retroperitoneal leiomyomas with intratumoral bleeding. This case highlights the importance of recognizing intratumoral haemorrhage in patients with large leiomyomas and a progressive decrease in haemoglobin after ruling out external haemorrhage. If necessary, dynamic monitoring via CT may help clarify the diagnosis.
