Third branchial cleft cysts (BCCs) are rare entities that represent abnormal persistence of the branchial apparatus. On CT examination, these cysts appear as homogeneous low-attenuation masses with well-circumscribed margins; on MR imaging, they demonstrate variable signal intensity on T1-weighted images and are hyperintense relative to muscle on T2-weighted images. Definitive treatment is surgical excision. We present a case of a third BCC and describe its diagnosis and treatment.
第三鳃裂囊肿(BCC)是一种罕见的疾病,代表鳃器的异常持续存在。在 CT 检查中,这些囊肿表现为均匀的低衰减肿块,边界清楚;在磁共振成像(MRI)上,它们在 T1 加权图像上表现出可变的信号强度,并且在 T2 加权图像上相对于肌肉呈高信号强度。明确的治疗方法是手术切除。我们报告了一例第三鳃裂囊肿,并描述了其诊断和治疗。
