Overview
Telangiectatic hyperplastic nodules (THNs) are benign hepatic lesions characterized by abnormal vascular proliferation and bile ductular structures. These nodules can occasionally present with calcification and are rarely reported in pediatric populations 1.Diagnosis
Imaging Findings: Transabdominal ultrasound and MRI may show calcification and intense arterial enhancement, but definitive differentiation from malignancy can be challenging 1.
Pathological Confirmation: Essential for definitive diagnosis; features include proliferative vascular lining cells (CD34 positive) and normal bile ducts (CK7 and CK19 positive) 1.Management
Surgical Resection: Recommended for symptomatic lesions or when imaging cannot exclude malignancy due to location and size concerns 1.
Observation: May be appropriate for asymptomatic, well-characterized benign lesions without suspicious features 1.Special Populations
Pediatrics: THNs with vascular malformations and calcifications are exceptionally rare in children; surgical intervention may be necessary for definitive diagnosis and management 1.Key Recommendations
Perform imaging studies (ultrasound, MRI) for initial evaluation of liver nodules, but consider surgical resection if imaging is inconclusive or lesion characteristics warrant concern for malignancy (Evidence: Weak 1).
Pathological examination is crucial for confirming the diagnosis of telangiectatic hyperplastic nodules, especially in pediatric cases (Evidence: Weak 1).
Laparoscopic wedge liver resection is indicated for definitive management when imaging cannot rule out malignancy or due to lesion characteristics and location 1 (Evidence: Expert opinion).References
