Long-term follow-up of patients with extensive segmental infantile hemangioma of the cervical or facial region: A French single-center prospective study.

Infantile hemangiomas (IHs) can be part of PHACE (posterior fossa anomalies, hemangioma, arterial anomalies, cardiac anomalies, eye anomalies) syndrome when they are segmental, extensive, and located on the face or neck. The initial assessment is codified and well known, but there are no recommendations for the follow-up of these patients. The aim of this study was to assess the long-term prevalence of different associated abnormalities. Patients with a history of large segmental IHs of the face or neck. diagnosed between 2011 and 2016 were included in the study. Each patient underwent an ophthalmological, dental, ENT (ear, nose, and throat), dermatological, neuro-pediatric, and radiological assessment at inclusion. Eight patients including five with PHACE syndrome were prospectively evaluated. After a mean follow-up of 8.5 years, three patients presented with an angiomatous aspect of the oral mucosa, two with hearing loss, and two with otoscopic abnormalities. No patients developed ophthalmological abnormalities. The neurological examination was altered in three cases. Brain magnetic resonance imaging follow-up was unchanged in three out four patients and revealed atrophy of the cerebellar vermis in 1 patient. Neurodevelopmental disorders were found in five of the patients and learning difficulties were observed in five patients. The S1 location appears to be associated with a higher risk of neurodevelopmental disorders and cerebellar malformations, while the S3 location was associated with more progressive complications, including neurovascular, cardiovascular, and ENT abnormalities. Our study reported late complications in patients with a large segmental IH of the face or neck, whether associated with PHACE syndrome or not, and we proposed an algorithm to optimize the long-term follow-up.
