頭部外傷後に発症した多発性骨腫瘍を伴う頭蓋骨悪性リンパ腫の1例

A Case of Malignant Lymphoma in the Skull after Head Injury associated with Multiple Bone Tumors

I．はじめに

　近年，脳内原発悪性リンパ腫の報告が数多くみられるが，最近われわれは頭部外傷後に打撲部の頭蓋骨腫瘍で発症し，全身骨に多発性に生じた悪性リンパ腫の1例を経験した．このような症例は稀であり，文献的考察を加えて報告する．

A case of malignant lymphoma in the skull after head injury associated with whole bone metastasis is reported. The patient was a 66-year-old man who was admitted to Almeida Memorial Hospital because of headache and general fatigue 2 months after head injury. After admission tumors appear in the frontal and occipital region and grew rapidly. Plain cranio-gram revealed large map-like bone destructions and multiple punched out lesions. Bone scintigram with ^99mTc-MDP revealed multiple accumulations of RI in the skull, vertebrae, ribs and pelvis.
