A
Morel-Lavallée lesion is a closed internal degloving injury where skin and fat shear off from the underlying fascia, creating a fluid-filled pocket (blood + lymph + necrotic fat). It’s usually traumatic and often missed early.
What this case report highlights
“Chronic … in a Pediatric Competitive Dancer” means:
Pediatric → child/adolescent (rare in this age group)
Competitive dancer → repetitive shear, splits, floor work, hip impact
Chronic → lesion persisted and formed a capsule, harder to treat
Typical presentation in the report
Slowly enlarging soft, fluctuant swelling
Often hip, thigh, or pelvis
May be painless or mildly sore
Misdiagnosed as hematoma, bursitis, or tumor
Why dancers are at risk
Repeated friction/shear over hip/thigh
Floor choreography
Overstretching + microtrauma
Minimal single “big” injury → diagnosis delayed
Imaging used
MRI is the gold standard
Shows:Fluid collection between tissue planes
Capsule formation (chronic stage)
Internal debris/fat globules
Treatment (chronic cases)
Compression alone → usually fails
Aspiration → often recurs
Sclerotherapy → sometimes used
Surgical excision of capsule → most definitive for chronic lesions
Key takeaway
Acute = fluid pocket
Chronic = encapsulated pseudo-cyst that won’t resolve without intervention
Clinical pearl:
If a dancer has a persistent soft swelling over hip/thigh lasting weeks–months, think Morel-Lavallée, not just “old hematoma.”
Want me to:
show MRI appearance
explain acute vs chronic staging
connect to sports medicine implications
summarize the exact case outcome
Just say.
