Spontaneous perirenal hemorrhage in systemic lupus erythematosus: a rare case report and literature review

摘要

CT and renal artery angiography images: a Abdominopelvic non-contrast CT demonstrated abnormal left kidney contour that was interiorly displaced and externally compressed. A large but limited subcapsular collection with mixed density lateral to the left kidney was seen, with an overall size of 5.8 × 10.1 × 11.7 cm, red arrow; b Contrast-enhanced abdominopelvic CT showed renal parenchymal laceration> 1 cm in depth without collecting system rupture or urinary extravasation. The subcapsular hematoma was shrunk than before with an overall left kidney size of about 4.7 × 8.9 × 11.7 cm, red arrow. In contrast, the right kidney filled uniformly with intravenous dye and showed no obvious sign of injury; c The left kidney was significantly deformed due to suppression. Renal arteriography identified active contrast extravasation from a distant branch of the left renal artery, red arrow; d Post-embolization film showed successful obliteration of bleeding branch, red arrow
