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.

肾周血肿包膜切除术改善Page肾1例

导读：由于肾实质受到外部压迫和肾脏灌注不足，页岩肾会引起继发性高血压。病例介绍一名 21 岁的健康男子在右腰部擦伤 3 个月后，在体检中被诊断为高血压。患者的血压为 176/120 mmHg。计算机断层扫描显示，右肾周围有一个巨大的包裹性囊性病变，肾实质受到严重的外部压迫。二巯丁二酸肾脏闪烁扫描显示右侧分肾功能减退。因此，患者被诊断为 Page 肾。对血肿进行了经皮引流。然而，血肿再次扩大。随后进行了囊肿切除术。病理结果显示囊纤维化，内囊层毛细血管增生。切除囊肿后，患者的血压恢复正常。结论从纤维化囊渗出的血液很可能维持了血肿。建议对涉及会阴部包裹性血肿的病例进行囊切除术。
