Morel-Lavallee Lesion Associated With Rhabdomyolysis in Polytrauma

We describe the case of a 30-year-old man who allegedly had a history of road traffic accidents. While walking on the road, he was hit by a truck. He presented with complaints of facial injuries and being unable to move his right lower limb. On examination, there is a 15x4 cm lacerated wound in the perineal area, with left testes exposed; anal tone could not be assessed; the right lower limb is externally rotated; and deformity is present with palpable peripheral pulses. He was diagnosed with a right sacral ala fracture, a distal one-third shaft of the right tibia fracture, and a right suprapubic rami fracture. Ultrasound of the right thigh showed hematoma and subcutaneous edema all around the gluteal and inguinal regions and fluid collection in the right inguinal region, which is suggestive of Morel-Lavallee lesion (MLL) type 6. On day two of admission, urine was dark in color, and creatinine kinase was elevated, which is suggestive of rhabdomyolysis. He was managed with hydration, electrolyte correction for rhabdomyolysis, and wound debridement for MLL apart from perineal injury, right sacral ala fracture, right suprapubic rami fracture, and distal one-third shaft of the right tibia fracture, with perineal repair and loop colostomy, pelvic binder, and external fixator, respectively. Early identification of the MLL associated with rhabdomyolysis in this polytrauma patient led to recovery and a successful outcome.
