The "Page kidney"

A Rare Case of Page Kidney With Superimposed Infection

Page kidney (PK) is a rare renal condition characterized by external compression of the kidney, typically by a subcapsular hematoma, leading to resistant secondary hypertension due to hypoperfusion and ischemia. This hypertension is caused by the external compression of the kidney by a chronic subcapsular hematoma that activates the renin-angiotensin-aldosterone system (RAAS) system. Hematoma formation can result from external or internal trauma. The resolution of the hematoma can take months, and, in some cases, may necessitate a nephrectomy. Unresolved subcapsular hematomas can be complicated by infection, leading to sepsis, hospitalization, and the need for surgical drainage. This report presents a unique case of a 67-year-old female with a spontaneous left renal subcapsular hematoma that did not resolve with conservative measures and was complicated by superimposed infection requiring percutaneous drainage.

Renal Subcapsular Hematoma Formation Due to Hydronephrosis Caused by Recurrent Uterine Cervical Cancer

Most non-traumatic renal subcapsular hematomas are found in the presence of primary or metastatic renal tumors, or in the presence of vascular disease of the renal blood vessels. We managed an asymptomatic renal subcapsular hematoma that formed due to uterine cervical cancer that metastasized to the left common iliac lymph nodes. A 48-year-old woman with stage IB1 cervical cancer underwent neoadjuvant chemotherapy and concurrent chemoradiation following a radical hysterectomy. Six months after the completion of her first treatment, she developed left-sided hydronephrosis, a left subcapsular hematoma and left common iliac lymph nodes enlargement as demonstrated with contrast-enhanced computed tomography. Although a renal subcapsular hematoma is rarely a symptom of cervical cancer recurrence, it should be considered if other neoplastic or vascular diseases are ruled out.

Overview of spontaneous intraabdominal tumor hemorrhage: etiologies, imaging findings, and management

Hemorrhage is a potential complication of benign and malignant tumors and tumor-like conditions in the abdomen. Patients often have non-specific presentations, although they may present critically ill and hemodynamically unstable. Imaging plays an important role not only in the diagnosis of hemorrhage but also in the detection and characterization of an underlying mass. Ultrasound, computed tomography, and magnetic resonance imaging are utilized in evaluating these patients, with each having particular strengths and limitations. Spontaneous tumor hemorrhage is most commonly seen in hepatic and renal lesions, although it can arise from nearly every abdominal organ. In this article, we will review principles of tumor hemorrhage, illustrate common and uncommon imaging features, and highlight different options for management.
