“…The distinction between these lesions by enhancement pattern can be difficult. However, abundant central vessels, especially thickly distorted vessels were observed in these lesions, which is a characteristic radiographic features of Epi-HAML compared with other hypervascular hepatic tumors [9]. The other two lesions with small or no vessels continued enhanced in the portal venous/delayed phase.…”

The purpose of our study was to retrospectively evaluate the computed tomography (CT)/magnetic resonance imaging features of epithelioid angiomyolipoma of the liver (Epi-HAML), with pathology as a reference. We reviewed the CT/MRI findings of six lesions of Epi-HAML and found absence of adipose tissue in the lesions. In addition, recognizing the imaging features of no capsule, and hypervasularity with central punctiform or filiform vessels as a characteristic enhancement may distinguish Epi-HAML from other hepatic tumors.

Three cases of angiomyolipoma: diagnostic imaging by contrast-enhanced ultrasonography

et al. 2009

We used contrast-enhanced ultrasound using the Sonazoid microbubble contrast agent to diagnose three cases of hepatic angiomyolipoma, which is a rare benign tumor. Some characteristic findings are obtained in the early vascular phase, for example fork-like tumor vessels. However, a variety of findings are seen after the early vascular phase because of microbubbles circulating the vascular enriched tumor.

“…Magnetic resonance imaging findings include the presence of hypointensity or hyperintensity of T1-weighted images and hyperintensity on T2-weighted images. 10,11 In our case, low-mechanical index real-time contrast-enhanced sonography showed strong enhancement in the thick solid rim but no enhancement in the predominantly cystic internal part of the lesion, indicating internal cystic degeneration due to hemorrhage and necrosis. The tumor was obviously enhanced in the solid rim from early arterial phase to the late phase.…”

Hepatic angiomyolipoma is a rare, benign, hepatic mesenchymal neoplasm. We report a case of an extremely large hepatic angiomyolipoma in a 58-year-old woman with unusual sonographic features. The tumor was well demarcated from the surrounding liver and showed a heterogeneous cystic appearance with a thick echogenic rim. Color Doppler showed blood flow in the echogenic rim and around the lesion. Contrast sonography demonstrated strong enhancement in the solid rim from early arterial phase to the late phase and no enhancement in the central cystic part of the lesion. Spiral CT showed a well-defined huge heterogeneous cystic mass with fatty density. At surgery the tumor was soft and encapsulated with a thin, smooth membrane. The cut surface of the tumor revealed a cystic appearance with necrotic tissue. The diagnosis of hepatic angiomyolipoma was confirmed by immunohistochemistry.
