Abstract

INTRODUCTION

Page kidney causes secondary hypertension due to external compression of the renal parenchyma and renal hypoperfusion.

CASE PRESENTATION

A 21-year-old healthy man was diagnosed with hypertension during a medical examination 3 months after he had gotten a bruise at the right lumbar region. The patient's blood pressure was 176/120 mmHg. Computed tomography showed a large encapsulated cystic lesion around the right kidney and severe external compression of the renal parenchyma. Dimercaptosuccinic acid renal scintigraphy revealed decreased right split renal function. Therefore, the patient was diagnosed with a Page kidney. Percutaneous drainage of the hematoma was performed. However, the hematoma enlarged again. Capsulectomy was subsequently performed. The pathological findings revealed capsule fibrosis and hyperplasia of the capillaries in the inner capsule layer. After capsulectomy, the patient's blood pressure normalized.

CONCLUSION

Blood leakage from the fibrotic capsule likely maintained the hematoma. Capsulectomy is recommended in cases involving an encapsulated perineal hematoma.

摘要

引言

佩吉氏肾由于肾实质受到外部压迫和肾灌注不足而导致继发性高血压。

病例介绍

一名21岁健康男性在右腰部受伤3个月后的体检中被诊断为高血压。患者血压为176/120 mmHg。计算机断层扫描显示右肾周围有一个大的包膜性囊性病变，肾实质受到严重外部压迫。二巯基琥珀酸肾闪烁显像显示右肾分肾功能降低。因此，该患者被诊断为佩吉氏肾。对血肿进行了经皮引流。然而，血肿再次增大。随后进行了包膜切除术。病理检查结果显示包膜纤维化和内包膜层毛细血管增生。包膜切除术后，患者血压恢复正常。
