Spontaneous subepithelial hemorrhage: the Antopol-Goldman lesion

Antopol Goldman lesion: A case report

“…Imaging modalities may demonstrate a filling defect, mural thickening, and luminal narrowing of the renal pelvis and proximal ureters, which may be misdiagnosed as a tumor. However, hydronephrosis is rarely found [ 4 , 5 ].…”

“…It is of high importance to mention that CT, specifically the non-enhanced phase, is considered the best to diagnose such lesion and superior to the US. It shows the hyperdense hemorrhagic component on pre-contrast images, and shows non-enhancement of the lesion on contrast enhanced images [ 3 , 5 ].…”

“…However, it may involve the renal calyces and proximal ureter [ 3 , 4 ]. Although several factors, such as excessive analgesic or anticoagulant medication use, diabetes mellitus, hypertension, hemophilia, etc., were linked to the development of this lesion, the definitive cause is not well established yet [ 1 , 5 ].…”

“…This clinical presentation and the associated radiological findings on imaging modalities may be mistaken for renal tumors. Therefore, diverting the management toward more invasive, unnecessary surgeries, since such lesions are now managed conservatively, highlights the importance of diagnosing such lesions [ 5 – 8 ].…”
