Cervico-thoracic Morel-Lavallée lesion

Area of Science:

• Orthopedics
• Trauma Surgery
• Radiology

Background:

• Morel-Lavallée lesions (MLLs) are post-traumatic fluid collections typically found in the gluteal or thigh regions.
• These lesions result from shearing forces separating the subcutaneous tissue from the underlying fascia.
• Existing literature predominantly focuses on MLLs in the lower body, leaving atypical locations under-documented.

Observation:

• A case is presented of a woman in her 40s with a cervico-thoracic fluctuant collection following trauma.
• Imaging confirmed the diagnosis as a Morel-Lavallée lesion.
• This represents the first documented instance of an MLL in the cervico-thoracic region.

Findings:

• An orthoplastic approach was employed, leading to non-operative management utilizing a spinal brace.
• The cervico-thoracic MLL demonstrated complete resolution within three months of the initial injury.
• The patient remained symptom-free at the final follow-up appointment.

Implications:

• This case expands the known anatomical distribution of Morel-Lavallée lesions beyond the typical pelvic and thigh areas.
• It highlights the potential efficacy of conservative management, including bracing, for atypical MLLs in challenging locations.
• Further research into the diagnosis and management of MLLs in unusual anatomical sites is warranted.
