From the Guidelines
For a 1.8 x 1.6 x 1.5 cm hyperechoic solid lesion in the right hepatic lobe suggestive of a hemangioma, with a history of cholecystectomy and no ductal dilatation, I recommend observation with follow-up imaging in 6 months. Hepatic hemangiomas are benign vascular lesions that typically require no intervention when small (less than 4-5 cm) and asymptomatic, as supported by the guidelines for contrast-enhanced ultrasound for the characterization of focal liver lesions 1. The imaging characteristics described are classic for hemangioma, with peripheral nodular enhancement and complete or incomplete centripetal filling in the portal venous and late phases, yielding a sensitivity of 98% for histologically proven hemangiomas 1.
The small size of the lesion makes complications unlikely, and follow-up imaging, preferably with ultrasound or MRI with contrast, will confirm stability of the lesion. If the lesion remains stable after 1-2 follow-up scans, annual surveillance can be considered for several years, then potentially discontinued if no changes occur. No specific medications or treatments are needed at this time. The prior cholecystectomy is likely unrelated to this finding.
Some key points to consider in the management of this patient include:
- The use of contrast-enhanced ultrasound (CEUS) to characterize the focal liver lesion, which is very useful in the diagnosis of hepatic hemangioma 1
- The typical CEUS findings of liver hemangiomas, including peripheral nodular enhancement and complete or incomplete centripetal filling in the portal venous and late phases 1
- The importance of follow-up imaging to confirm stability of the lesion and rule out any changes or complications
- The low risk of complications associated with small, asymptomatic hepatic hemangiomas, and the rare need for surgical intervention 1.
If the patient develops right upper quadrant pain, rapid growth of the lesion, or other concerning symptoms, earlier reassessment would be warranted. Most hemangiomas remain stable throughout life and rarely require surgical intervention.
From the Research
Diagnosis and Management of Hepatic Lesions and Cholecystectomy
- The patient has a 1.8 x 1.6 x 1.5 cm hyperechoic solid lesion in the right hepatic lobe, suggestive of a hemangioma, and has undergone cholecystectomy without ductal dilatation 2.
- The diagnosis of hepatic lesions, such as hemangiomas, can be characterized using liver-specific contrast agents and imaging modalities like ultrasound and magnetic resonance imaging (MRI) 3.
- For patients with a history of cholelithiasis, clinical diagnosis of cholecystitis is an indication for urgent cholecystectomy, even in the absence of sonographic evidence of cholecystitis 4.
Post-Cholecystectomy Complications
- Post-cholecystectomy complications can include biliary duct injury or leak, biliary obstruction, remnant gallbladder/cystic duct stones and inflammation, biliary dyskinesia, papillary stenosis, and vascular injury 2.
- Imaging modalities like CT, sonography, ERCP, and MRCP can be used to evaluate post-cholecystectomy complications, with scintigraphy having higher sensitivity and specificity for diagnosing bile leaks 2.
Management of Alcoholic Hepatitis
- Alcoholic hepatitis is a clinical syndrome characterized by acute-onset jaundice and liver enzyme abnormalities in the setting of long-term heavy alcohol use 5.
- Diagnosis of alcoholic hepatitis is primarily clinical, and treatment options include supportive care, corticosteroids, and involvement of a multidisciplinary team 5.
Imaging Findings and Disease Severity
- The agreement between ERCP and MRCP in scoring bile duct changes for disease severity is only moderate, and MRI-MRCP seems to have a minor role as a surrogate marker of disease activity and progression in primary sclerosing cholangitis 6.
- Ultrasound and MRI have comparable abilities in characterizing non-hypervascular lesions, compensating mutually for the poor sensitivity of ultrasound and the poor specificity of MRI in the liver-specific phase 3.
