Simple bone cyst (SBC), also known as unicameral bone cyst, is a benign, fluid-filled cystic lesion that mainly appears in the long bones of young patients. Simple bone cysts are considered dysplastic or reactive lesions of bone. The most common locations for SBCs are the proximal humerus and femur. Lesions may occasionally be found in the jawbones. Simple bone cysts often have no clinical impact and are usually detected during routine radiographic examinations unless a gross pathologic fracture occurs. When symptoms develop, they may include mild pain, local tenderness and swelling. Computed tomography (CT) scans demonstrate a central, well-defined, mildly expansile or non-expansile, thin-walled lytic lesion, with little or no marginal sclerosis. Magnetic resonance imaging (MRI) usually confirms the cystic nature of the lesion by showing its fluid content. Cystic masses in the hyoid bone are very rare. Here we report an asymptomatic SBC in the hyoid bone, incidentally discovered in a cone-beam computed tomography (CBCT) examination, which appears to be the 2nd reported case.
单纯性骨囊肿（SBC），也称为单腔性骨囊肿，是一种良性、充满液体的囊性病变，主要出现在年轻患者的长骨中。单纯性骨囊肿被认为是骨的发育不良或反应性病变。SBC 最常见的部位是肱骨近端和股骨。偶尔也会在颌骨中发现病变。单纯性骨囊肿通常没有临床影响，除非发生明显的病理性骨折，否则通常在常规放射学检查中发现。当出现症状时，可能包括轻度疼痛、局部压痛和肿胀。计算机断层扫描（CT）显示中央、明确、轻度膨胀或非膨胀、薄壁溶骨性病变，边缘硬化很少或没有。磁共振成像（MRI）通常通过显示其液体含量来证实病变的囊性性质。舌骨中的囊性肿块非常罕见。我们在此报告一例在锥形束 CT（CBCT）检查中偶然发现的、无症状的舌骨单纯性骨囊肿，这似乎是第 2 例报道的病例。
