title: Cerebral dural sinus thrombosis in acute lymphoblastic leukemia with early diagnosis by fast fluid-attenuated inversion recovery (FLAIR) MR image: a case report and review of the literature.
abstract: Cerebral dural sinus thrombosis (CDST) is a very rare complication of acute lymphoblastic leukemia (ALL) in adult patients. A 23-year-old man with ALL developed dizziness, headache, diplopia, limb weakness, and a sensation of fullness in his head after his second induction chemotherapy with doxorubicin, prednisolone, and vincristine. Examinations of the peripheral blood, bone marrow, and cerebrospinal fluid showed no recurrent leukemic cells. Magnetic resonance (MR) imaging of the brain disclosed unexpected CDST at the left transverse sinus, which was seen only on the fast fluid-attenuated inversion recovery (FLAIR) sequence. His symptoms were relieved soon after treatment with heparin. MR imaging with FLAIR performed a second time 7 days later showed complete disappearance of the thrombosis. The patient was treated continuously with oral anticoagulant therapy and the symptoms did not recur. CDST can be diagnosed in its early phase by MR studies with FLAIR images. Anticoagulant therapy can be administered safely without precipitating the occurrence of infarction hemorrhage at such an early stage of CDST.
