Neurotoxicity of intrathecal methotrexate: MR imaging findings.

Diffusion-weighted MR imaging of early methotrexate-related neurotoxicity in children.

BACKGROUND AND PURPOSE Methotrexate is a major cause of treatment-related acute neurotoxicity in children with hematologic malignancies. The purpose of this study was to investigate whether diffusion-weighted MR imaging (DWI) detects acute methotrexate white matter neurotoxicity in this patient population. METHODS Six children-three female and three male-with hematologic malignancies were stu...

Acute methotrexate neurotoxicity: findings on diffusion-weighted imaging and correlation with clinical outcome.

BACKGROUND AND PURPOSE Acute lymphocytic leukemia (ALL) is a common malignancy of childhood treated with methotrexate (MTX), which is associated with acute neurotoxicity. We evaluated diffusion-weighted (DW) and conventional MR images in children with ALL and acute MTX-induced neurotoxicity, with clinical correlation. METHODS Five patients aged 12-15 years underwent fluid-attenuated inversion...

Intrathecal Methotrexate and Acute Neurotoxicity: A Painful Experience

Intrathecal treatment with methotrexate, an essential chemotherapeutic for both prophylaxis and treatment of central nervous system involvement of leukemia, may be associated with local neurotoxicity and/or systemic toxicity. Signs of acute neurotoxicity include confusion, disorientation, seizures, aphasia, ataxia, dysarthria, paresis and even paralysis. Presented here is a case of a 58 year ol...

Prevention of neurotoxicity by high-dose folinic acid rescue after high-dose methotrexate and intrathecal methotrexate without compromising cure inspite of previous transient leukoencephalopathy after intrathecal methotrexate.

Dear Editor, Methotrexate (MTX) is a frequently used chemotherapeutic agent in the treatment of childhood acute lymphoblastic leukaemia (ALL) and lymphoma. Besides oral and intravenous MTX, intrathecal MTX is an essential component of chemotherapy for ALL and is effective in preventing recurrences of central nervous system (CNS) leukaemia. Acute, subacute and chronic neurotoxicity have been obs...
