Key Points

To determine the relationship between segmental infantile hemangiomas and the risk of LUMBAR syndrome.
Systematic review of clinical photographs from 91 patients diagnosed with LUMBAR syndrome.
Analysis focused on the morphology and anatomical location of hemangiomas.
All identified hemangiomas were segmental and involved the midline of the lumbosacral area.
No cases of partial segmental lesions or midline-spared hemangiomas were found.
Findings indicate stratification of risk for LUMBAR syndrome based on hemangioma morphology.

Abstract

A systematic review of clinical photographs from 91 patients with LUMBAR syndrome demonstrated that infantile hemangiomas in affected individuals were consistently segmental in morphology and involved the anatomic midline of the lumbosacral, sacrococcygeal, or pelvic regions. No cases were "partial segmental" or spared the midline. The hemangiomas were transmedian in all patients except one, in whom the hemangioma was unilateral and abutted the midline, and thus paramedian. These findings support the conclusion that segmental infantile hemangiomas involving the anatomic midline confer risk for LUMBAR syndrome and therefore warrant evaluation, while strictly lateral lesions without involvement of the midline do not. This refinement in risk stratification has immediate implications for clinical assessment and management.
