Hepatic hemangiomas mimicking gastrointestinal stromal tumors: A case report

Table 1 Key imaging features for differential diagnosis of hepatic hemangioma and gastrointestinal stromal tumor

	CT	MRI	PET/CT	US	EUs
GIST	Initial diagnostic modality, size ≤ 2 cm, low detection; size > 2 cm, peripheral enhancement pattern, exophytic and hypervascular[4]	Similar to CT imaging, low signal intensity on T1WI, high signal intensity on T2WI, and enhanced signal intensity on post gadolinium image[13]	Shows a sensitivity of 89% and specificity of 97%[14]	Use for the diagnosis of hepatic metastases	size < 2 cm, hypoechoic solid mass accurately identifying a SEL[7]
Hepatic hemangioma	High detection, early peripheral nodular enhancement in the arterial phase and slow, progressive centripetal filling in the portal venous phase[9]	Differential diagnosis with other liver tumors, low signal intensity on T1WIs and appear hyperintense on diffusion-weighted imaging[15]	-	Initial diagnostic modality, presents as hyperechoic, or as hypoechoic masses with a hyperechoic rim[15]	-

CT: Computed tomography; MRI: Magnetic resonance imaging; PET: Positron emission tomography; US: Ultrasound; EUS: Endoscopic ultrasound; GIST: Gastrointestinal stromal tumor; T1WI: T1-weighted imaging; SEL: Subepithelial lesion.
