Cyst-like lesion in the coronoid process of the mandible is a challenging diagnosis to make, as it may present with a range of non-specific symptoms. A middle-aged woman reported a one-year history of non-bloody, pus discharge from the right angle of the mandible. There was a history of prior surgery comprising teeth removal two years ago for a painful swelling on the right side of her face, following which her symptoms regressed but in the due course, she developed a chronic sinus with draining abscess. Radiographic findings, in combination with clinical symptoms, are critical in the diagnosis and evaluation of cysts and cyst-like lesions of the jaws. The orthopantomograph (OPG) revealed a cyst-like lesion in the coronoid process of the mandible with an extra-oral sinus tract leading to the epicenter of the cyst-like radiolucency, and so this, in combination with the patient's atypical symptoms, presented a diagnostic challenge. This case report explores the events which led to the diagnosis of osteomyelitis and shows several unique learning points.
下颌骨冠突的囊肿样病变诊断颇具挑战性，因为它可能出现一系列非特异性症状。一名中年女性报告称，下颌骨右侧口角有一年非血性、脓性分泌物的病史。她曾在两年前因右侧面部疼痛肿胀接受过包括拔牙在内的手术，术后症状有所缓解，但随后她出现了一个伴有引流脓肿的慢性窦道。影像学检查结果结合临床症状，对于颌骨囊肿和囊肿样病变的诊断及评估至关重要。全景曲面断层片（OPG）显示下颌骨冠突有一个囊肿样病变，伴有一个通向囊肿样透射区中心的口外窦道，因此，这与患者的非典型症状相结合，带来了诊断挑战。本病例报告探讨了导致骨髓炎诊断的一系列情况，并展示了几个独特的学习要点。
