Abstract

Spontaneous bilateral quadriceps tendon rupture (QTR) is a rare but severely debilitating condition, often associated with delayed diagnosis due to its nonspecific presentation and wide differential diagnosis. We report the case of a 64-year-old obese male with a history of diabetes mellitus who presented to the emergency department with acute bilateral thigh pain and inability to ambulate following a non-traumatic incident. Physical examination revealed swelling, tenderness, palpable suprapatellar defects, and loss of active knee extension, with neurovascular status intact. Initial radiographs and computed tomography (CT) excluded fractures, and the patellae were in normal anatomical positions. Point-of-care ultrasound (POCUS) suggested bilateral QTR, subsequently confirmed by magnetic resonance imaging (MRI). The patient was referred for surgical management. Bilateral QTR predominantly affects males over 40 years, often in the presence of comorbidities such as chronic renal failure, diabetes, obesity, or connective tissue disorders. Although MRI is considered the gold standard for diagnosis, POCUS offers a rapid, cost-effective, and highly sensitive alternative in the emergency setting. Early recognition is crucial to prevent functional disability. Clinicians should maintain a high index of suspicion for QTR in patients presenting with acute extension deficits, even in the absence of trauma or radiographic abnormalities.

Özet

Spontan bilateral kuadriseps tendon rüptürü (QTR), nadir görülen ancak ciddi derecede güçten düşüren bir durumdur ve genellikle spesifik olmayan sunumu ve geniş ayırıcı tanısı nedeniyle gecikmiş tanı ile ilişkilendirilir. Travma dışı bir olaydan sonra akut bilateral uyluk ağrısı ve yürüyememe şikayetiyle acil servise başvuran, diabetes mellitus öyküsü olan 64 yaşında obez bir erkek hastayı bildiriyoruz. Fizik muayenede şişlik, hassasiyet, elle muayenede hissedilen suprapatellar defektler ve aktif diz ekstansiyon kaybı, nörovasküler durum sağlam olarak saptandı. İlk radyografiler ve bilgisayarlı tomografi (BT) kırıkları dışladı ve patellalar normal anatomik pozisyondaydı. Hasta başı ultrasonografisi (POCUS) bilateral QTR'yi önerdi ve daha sonra manyetik rezonans görüntüleme (MRG) ile doğrulandı. Hasta cerrahi tedavi için sevk edildi. Bilateral QTR, çoğunlukla 40 yaş üstü erkekleri etkiler ve genellikle kronik böbrek yetmezliği, diyabet, obezite veya bağ dokusu bozuklukları gibi eşlik eden hastalıkların varlığında görülür. MRI tanı için altın standart olarak kabul edilse de, POCUS acil serviste hızlı, uygun maliyetli ve oldukça hassas bir alternatif sunar. Fonksiyonel yetersizliği önlemek için erken tanı çok önemlidir. Klinisyenler, travma veya radyografik anormallikler olmasa bile, akut ekstansiyon defisitleriyle başvuran hastalarda QTR'den yüksek oranda şüphelenmelidir.
