# Imaging of infantile hemangiomas: a pictorial essay

## TL;DR

This paper uses images to show how infantile hemangiomas appear and develop, focusing on imaging techniques to distinguish them from other conditions.

## Contribution

The paper presents a visual guide to the imaging features of infantile hemangiomas for accurate diagnosis.

## Key findings

- Infantile hemangiomas have a distinct growth pattern that peaks at one year and then regresses.
- Imaging methods like ultrasound and MRI help differentiate IHs from other vascular and non-vascular tumors.
- Illustrative cases highlight the varied appearances of IHs on imaging.

## Abstract

Infantile hemangioma (IH) is a common benign vascular neoplasm with a
characteristic pattern of progression: at birth, it is not fully developed; in
the first days or weeks of life, it grows; and its growth peaks at around one
year of age, after which there is spontaneous regression. Although most IHs are
superficial and therefore obvious on physical examination, they can also affect
deeper planes or other organs, in which case they are best assessed with imaging
examinations. Methods such as ultrasound and magnetic resonance imaging can help
differentiate IHs from vascular malformations, other benign tumors, and
malignant tumors. The aim of this pictorial essay is to demonstrate the various
presentations of IHs through illustrative cases, with an emphasis on imaging
findings.
