Area of Science:

• Vascular Malformations
• Neurology
• Pediatrics

Background:

• Klippel Trenaunay Weber Syndrome (KTWS) is a rare congenital disorder characterized by vascular malformations, limb hypertrophy, and cutaneous abnormalities.
• The syndrome's etiology remains largely unknown, with current research focusing on genetic and developmental factors.

Observation:

• A 13-year-old male presented with significant lower limb asymmetry, a hallmark of KTWS.
• Clinical examination revealed a lower motor neuron lesion affecting the left lower limb, impacting motor function.

Findings:

• The patient's presentation highlights the complex and variable phenotype of KTWS, extending beyond typical vascular and skeletal manifestations.
• The co-occurrence of a lower motor neuron lesion with limb asymmetry in this case is noteworthy and requires further investigation.

Implications:

• This case underscores the importance of a multidisciplinary approach in diagnosing and managing KTWS, involving vascular specialists, neurologists, and orthopedic surgeons.
• Further research into the neurological complications associated with KTWS may lead to improved diagnostic criteria and therapeutic strategies.
• Understanding the interplay between vascular malformations and neurological deficits in KTWS is crucial for optimizing patient outcomes.
