Prenatal Ultrasound and Magnetic Resonance Imaging Features and Postnatal Outcomes of Congenital Hepatic Hemangioma: A Retrospective Analysis
ABSTRACT Background Congenital hepatic hemangioma (CHH) is a rare benign vascular tumor that occurs prenatally. However, only a few cases have been summarized and evaluated for the prenatal and postnatal imaging features of CHH, and no studies have conducted long‐term follow‐up on it. This study aim...

| description | ABSTRACT Background Congenital hepatic hemangioma (CHH) is a rare benign vascular tumor that occurs prenatally. However, only a few cases have been summarized and evaluated for the prenatal and postnatal imaging features of CHH, and no studies have conducted long‐term follow‐up on it. This study aimed to explore the ultrasound and magnetic resonance features, growth patterns, and clinical outcomes of CHH. Methods Thirty‐six pregnancies with a prenatal fetal diagnosis and postnatal diagnosis of CHH were studied. CHHs were grouped into those with a diameter ≥ 4 cm and those with a diameter < 4 cm according to the largest diameter. Fisher's exact test was used to compare the imaging characteristics between the groups. The volume of CHHs was measured at each follow‐up visit to plot the growth pattern of the tumors, and the volume of CHHs was compared before and after birth using a rank sum test analysis. Results Thirty‐three cases of CHHs were confirmed by postnatal imaging, and three were confirmed by a biopsy. Mixed echoes were more common in the diameter ≥ 4 cm group than in the diameter < 4 cm group (p = 0.026). Complications were more likely to occur in the large‐diameter group. Eighteen (54.5%) cases were classified as rapidly involuting congenital hemangioma, nine (27.3%) as partially involuting congenital hemangioma, and two (6.1%) as noninvoluting congenital hemangioma. A new type of CHH was identified in which four (12.1%) cases continued to proliferate after birth and spontaneously subsided in subsequent months. The CHH volume decreased with age and was significantly decreased at 9 months postnatal compared to birth (p = 0.001). Conclusion This study showed the imaging features of CHH were associated with the lesion size. Based on postnatal follow‐up, a new type of CHH was identified. If there are no complications at birth in CHH cases, a good prognosis is indicated. |
