Overview
Hepatic hemangiomas are benign vascular tumors characterized by dilated sinusoidal spaces within liver parenchyma. They are typically asymptomatic and discovered incidentally, though complications such as pain, bleeding, or compression can occur 234.Diagnosis
Imaging: Ultrasound (US), CT, MRI, and contrast-enhanced ultrasound (CEUS) are primary diagnostic tools 12.
CEUS Artifacts: Recognize "pseudowashout" artifacts that can mimic complications like necrosis 1.
Grading: Size classification (e.g., giant hemangiomas > 10 cm) aids in management decisions 2.
Differential Diagnosis: Rule out other liver lesions including malignancies through imaging characteristics and clinical context 2.Management
Conservative Management: Recommended for asymptomatic lesions 2.
Surgical Intervention: Indicated for symptomatic lesions, complications (e.g., abscess formation), or large hemangiomas requiring resection 45.
Hemorrhage Control: Teflon strips sutured with catgut for controlling bleeding during resection 5.Special Populations
Comorbidities: Abdominal pain in patients with hemangiomas may be associated with irritable bowel syndrome or other gastrointestinal diseases 2.
Giant Hemangiomas: Higher risk of complications necessitates closer monitoring and potential surgical intervention 24.Key Recommendations
Monitor Asymptomatic Lesions: Regular imaging follow-up is advised for asymptomatic patients to detect any changes 2 (Evidence: Moderate).
Surgical Consideration for Symptomatic or Giant Lesions: Consider surgical resection for symptomatic lesions or those exceeding 10 cm to prevent complications 24 (Evidence: Moderate).
Recognize Pseudowashout Artifacts: Be aware of CEUS artifacts that can mimic complications to avoid unnecessary interventions 1 (Evidence: Expert opinion).References
