Abstract

A 46-year-old man presented with a 3-month history of epistaxis. CT and MRI scan showed a soft tissue mass in the left nasal cavity. An excisional biopsy of the mass revealed extramedullary plasmacytoma. 18F-FDG PET/CT showed intense activity in the region of the left nasal cavity but no other FDG-avid lesions. Additional workups did not reveal any evidence of systematic disease. Based on these findings, the patient was diagnosed as having solitary nasal extramedullary plasmacytoma. He received the local radiation therapy. During the 3-month follow-up, his symptom was relieved.

摘要

一位 46 岁男性因鼻出血就诊，病史 3 个月。CT 和 MRI 扫描显示左鼻腔软组织肿块。肿块的切除活检显示髓外浆细胞瘤。18F-FDG PET/CT 显示左鼻腔区域活性明显增高，但无其他 FDG 摄取病灶。进一步检查未发现任何系统性疾病的证据。根据这些发现，患者被诊断为孤立性鼻腔髓外浆细胞瘤。他接受了局部放射治疗。在 3 个月的随访期间，他的症状得到缓解。
