Brief Summary
The objective of this study is to determine the maximal diameter threshold at which infants with lumbosacral, sacrococcygeal, perineal, gluteal, or lower-limb extending infantile hemangiomas should undergo screening for LUMBAR syndrome.

Outcome Measures
Primary Outcomes (1)
The primary outcome will be the presence of at least one LUMBAR-associated structural anomaly detected by standardized screening.
LUMBAR-associated anomalies include spinal or spinal cord anomalies, urogenital anomalies, renal anomalies, anorectal malformations, bony deformities, arterial anomalies, or other regional developmental abnormalities consistent with the LUMBAR spectrum.
2 weeks
Secondary Outcomes (3)
Detection rate of spinal or spinal cord anomalies.Detection rate of anorectal, perineal, or urogenital anomalies. Detection rate of arterial or lower-limb developmental anomalies.
2 weeks
Detection rate of renal or urinary tract anomalies.Detection rate of LUMBAR-associated anomalies according to lesion location.Detection rate according to lesion diameter category.
2 weeks
Proportion of patients requiring further specialist treatment or intervention.

Eligibility Criteria
The study population will consist of infants clinically diagnosed with infantile hemangioma involving the lower-body region, including the lumbosacral, sacrococcygeal, gluteal, perineal, perianal, external genital, or continuously extending lower-limb areas. Eligible patients will be prospectively and consecutively recruited from participating centers. The target population is selected because infantile hemangiomas in these anatomical regions, particularly large or segmental lesions, may be associated with LUMBAR syndrome or LUMBAR-associated structural anomalies. Patients with a maximal lesion diameter of ≥2.0 cm will be included in order to allow evaluation of different candidate screening thresholds. The 2.0-cm cutoff will serve as the enrollment threshold rather than the final screening threshold. This design enables comparison of clinically relevant candidate cutoffs, including ≥2.0 cm, ≥2.5 cm, ≥3.0 cm, ≥4.0 cm, and ≥5.0 cm, for predicting LUMBAR-associated anomalies.
You may qualify if:
- Clinically diagnosed infantile hemangioma.
- Lesion located in at least one of the following regions: lumbosacral region, sacrococcygeal region, gluteal region, perineal region, perianal region, external genital region, or continuous extension to the lower limb.
- Maximal lesion diameter ≥2.0 cm.
- Written informed consent obtained from the parents or legal guardians.
You may not qualify if:
- Vascular anomaly other than infantile hemangioma, such as venous malformation, lymphatic malformation, arteriovenous malformation, or congenital hemangioma.
- Previously diagnosed genetic or congenital syndrome unrelated to LUMBAR syndrome, which may independently explain the detected anomalies.
- Incomplete clinical data preventing accurate measurement of lesion diameter.
- Refusal of participation or refusal to complete core screening examinations.
- Any condition judged by the investigators to be unsuitable for study participation.
