Lumbar Syndrome and Segmental Infantile Hemangiomas: Diagnosis, Workup, and Difficult Ulceration Management

The speaker presents cases of newborns with segmental, reticulated infantile hemangiomas in the lumbar/sacral or lower-limb region that initially mimicked vascular malformations because the lesions were violaceous or only faintly red at birth. In the first case, the infant also had anorectal and urogenital abnormalities and later developed a massive, painful ulceration; workup revealed a spinal lipoma, duplicated renal collecting system, and abnormal external genitalia, fitting lumbar syndrome (lower body hemangioma, urogenital abnormalities, and myelomalformations/other associated anomalies). Management required a multidisciplinary approach, serial imaging and evaluations, wound care, pain control, blood transfusion, and escalating propranolol with corticosteroids, with eventual resolution but significant scarring. A second infant with a similar segmental hemangioma and severe ulceration improved much more quickly when propranolol was started early and no other anomalies were found. The talk emphasizes that lumbar/sacral segmental infantile hemangiomas should trigger prompt evaluation for associated spinal, renal, genital, anorectal, and cardiac anomalies, and that ulcerations in lumbar syndrome can be unusually aggressive and difficult to treat. The speaker also notes possible links to regional hypoxia and references updated terminology from a recent consensus review.
