ABSTRACT

Diagnosis: Perinephric/Subcapsular Hematoma

History: 22 year old male with nephrotic syndrome of undetermined etiology undergoing ultrasound guided percutaneous renal biopsy.

Findings: Ultrasound initially demonstrates the normal sonographic appearance of the left kidney prior to percutaneous biopsy. Note the normal cortical and medullary differentiation as well as the intact perinephric hyperechoic cortical-capsular interface. Ultrasound image selected during the second pass core biopsy (using a spring loaded biopsy needle) demonstrates the course of the biopsy needle. Ultrasound image captured following the cessation of core biopsy attempts demonstrates complete loss of the previously seen hyperechoic cortical-capsular interface. A wide and slightly irregular perinephric hypoechogenic fluid collection is seen posteriorly (patient prone) most likely representing hematoma. Selected axial non-contrast CT slices through the level of the kidneys (taken minutes after the post-biopsy ultrasound) demonstrates left posterior-lateral and inferior perinephric hyperattenuation consistent with acute hemorrhage. The slightly irregular margin of the abnormality suggests this lesion is both subcapsular and perinephric.
