A case of cervical actinomycosis

放線菌症はActinomyces属の感染による特異性炎症であり，頸顔面領域に好発し，顎骨周囲炎，多発膿瘍，開口障害といった症状を呈することが一般的に知られている^1-10）。

We reported a case of 8-year-old boy presented with right cervical swelling, feeling hot, and the pain, which were caused by actinomycosis. Contrast-enhanced CT and MR images showed right cervical enhancing mass mimicking a tumor. The mass spread beyond fascia and, demonstrated focal non-enhancing areas suggesting abscess, which may be helpful for the diagnosis of actinomycosis. It is important to distinguish cervical actinomycosis from cervical tumor, because early diagnosis can help to choose the appropriate treatment.
