Sonography, CT, and MRI of Giant Cavernous Hemangioma of the Kidney: Correlation with Pathologic Findings

Cavernous hemangioma mimicking a cystic renal cell carcinoma

“…5 The sonographic fi ndings are nonspecifi c, and have been reported as hyperechoic tumor 1 or hypoechoic tumor. 6 Power doppler sonography revealed a normal renal vascular pattern rather than a pattern specifi c to hemangioma. 6 These fi ndings may mimic more common tumors of the kidney, including renal cell carcinoma and transitional cell carcinoma On the CT fi ndings, renal cavernous hemangioma is reported as a mass that is isodense relative to the renal cortex during the excretory phase, and as a homoge- neously enhanced mass with peripheral hypoenhancement during the portal phase.…”

Beyond hepatic hemangiomas: the diverse appearances of gastrointestinal and genitourinary hemangiomas

“…On MRI, lesions are typically uniformly hypointense on T1W sequences and are homogeneously hyperintense on T2WI sequences, with possible flow voids [82,86,91]. Following contrast administration, lesions may be hypervascular or hypovascular, and the typical peripheral nodular enhancement and progressive fill-in may be seen [91].…”

“…Traditionally, these lesions have been treated with partial or complete nephrectomy owing to the inability to exclude malignancy or to curtail clinically significant hematuria [91]. Selective embolization and papillectomy have been mentioned as potential alternatives depending on size and location [82,86,90].…”

Renal Parenchymal Neoplasms

“…On computed tomography, renal hemangiomas usually present as soft tissue density tumors with heterogeneous enhancement [ 16 ]. On magnetic resonance imaging, renal cavernous hemangioma has been reported as hypointense on T1-weighted image and predominant hyperintensity mass with visible fl ow void areas by vasculature on T2-weighted images [ 18 ]. On ultrasound, renal hemangioma presents as a hyperechoic or isoechoic mass [ 16 -18 ].…”
