Abstract

Introduction: Morel-Lavallée lesions are rare closed degloving injuries resulting from traumatic shear forces that separate the subcutaneous tissue from the underlying fascia. Although they most frequently occur in the pelvis and thigh, thoracolumbar involvement is exceedingly uncommon and may be underrecognized in trauma settings, leading to delays in diagnosis. Case Report: A 22-year-old man was admitted following a motor-vehicle accident with left-sided pulmonary contusion and pneumothorax and was managed conservatively. On the second day of hospitalization, his hemoglobin level abruptly fell to 5 g/dL despite stable daily thoracic imaging. Subsequent cross-sectional studies revealed a 25-cm hematoma extending from the thoracolumbar region into the left gluteal and lateral thigh compartments, consistent with a Morel-Lavallée lesion. The patient was managed conservatively with compression and transfusion of four units of erythrocyte suspension, resulting in clinical stabilization and full recovery. Conclusion: Thoracolumbar Morel-Lavallée lesions are rare but may lead to substantial concealed blood loss. They should be considered in trauma patients presenting with unexplained anemia. Early imaging—CT for rapid assessment and MRI for definitive characterization—supports timely diagnosis, and carefully selected patients may achieve complete recovery with vigilant conservative management.

Özet

Giriş: Morel-Lavallée lezyonları, travmatik kayma kuvvetlerinin deri altı dokuyu alttaki fasyadan ayırması sonucu gelişen nadir kapalı degloving yaralanmalarıdır. En sık pelvis ve uyluk bölgesinde görülmekle birlikte, torakolomber yerleşim son derece nadirdir ve travma ortamında sıklıkla gözden kaçabildiğinden tanıda gecikmelere yol açabilir Olgu Sunumu: Yirmi iki yaşındaki erkek hasta, araç içi trafik kazası sonrası sol akciğer kontüzyonu ve pnömotoraks nedeniyle kliniğimize kabul edildi ve konservatif olarak tedavi edildi. Hastaneye yatışının ikinci gününde, günlük akciğer grafilerinde stabil görünüm olmasına rağmen hemoglobin düzeyi ani şekilde 5 g/dL’ye düştü. Yapılan kesitsel görüntülemelerde, torakolomber bölgeden başlayıp sol gluteal bölge ve uyluk laterali boyunca uzanan 25 cm’lik hematom Morel-Lavallée lezyonu ile uyumlu bulundu. Hastaya kompresyon tedavisi ve dört ünite eritrosit süspansiyonu replasmanı uygulandı; klinik olarak stabilize olan hasta tamamen iyileşti. Sonuç: Torakolomber yerleşimli Morel-Lavallée lezyonları nadir görülmekle birlikte belirgin gizli kan kaybına neden olabilir ve açıklanamayan anemi ile başvuran travma hastalarında mutlaka akılda tutulmalıdır. Hızlı değerlendirme için BT ve kesinleştirme için MRG ile erken görüntüleme tanıyı kolaylaştırır. Uygun seçilmiş hastalarda dikkatli konservatif yaklaşım ile tam iyileşme sağlanabilir.
