Methotrexate-induced leukoencephalopathy is to be considered as a potential etiology in any patient presenting with stroke-like symptoms after receiving methotrexate. One of our cases suggests that the method of administration of the methotrexate can be IV or intrathecal and still results in leukoencephalopathy.

Methotrexate-induced leukoencephalopathy presenting as acute-onset limb weakness in a child: a case report.
J Med Case Rep

Colombo North Teaching Hospital, Ragama, Sri Lanka.
Article Synopsis
- Methotrexate is a key medication for treating childhood cancers like acute lymphoblastic leukemia but can lead to severe side effects such as neurotoxicity, specifically leukoencephalopathy, which usually presents with gradual neurological symptoms.
- A case involving a 10-year-old boy showed acute neurological symptoms, including limb weakness and involuntary movements, after taking oral methotrexate, a rare occurrence compared to traditional administration routes like injection.
- MRI scans revealed brain abnormalities consistent with methotrexate-induced neurotoxicity, highlighting the need for careful monitoring of neurological effects even with oral use of the drug.
Methotrexate (MTX) is used to treat acute lymphoblastic leukemia (ALL). It acts by inhibiting cell proliferation through its role as a folate antagonist. Despite its positive impact on patients' survival, high-dose MTX therapy carries risks, notably neurotoxic side effects such as subacute leukoencephalopathy that can mimic stroke symptoms.

Methotrexate-induced neurotoxicity is a well-defined side-effect of high-dose and intrathecal methotrexate with characteristic clinico-radiological findings and transient nature. Our experience in managing this entity in children with acute lymphoblastic leukemia(ALL) is reported here. All children with de novo ALLregistered from January 2016 through December 2021 who developed methotrexate-induced neurotoxicity were included.

Article Synopsis
- New cancer treatments, especially immunotherapy, are helping patients live longer and feel less sick, but there are still problems that can come from these therapies.
- Doctors who look at brain images, called neuroradiologists, can spot signs of these problems early on.
- The article explains various complications from different treatments, like chemotherapy and radiation, and stresses how important it is for doctors to recognize these issues to help patients stay safe and healthy.

Methotrexate (MTX) is potent chemotherapeutic agent, often administered intrathecally to treat or prevent central nervous system involvement in lymphomas and leukemias, particularly T-cell lymphoblastic leukemia (T-LBL). MTX has been linked to adverse neurologic effects that mimic acute stroke, including facial drooping, hemiplegia, impaired consciousness, and seizures, as well as changes on imaging-known as MTX-induced leukoencephalopathy (LE). We report a case of a 17-year-old male diagnosed with T-LBL, who had been receiving MTX chemotherapy for 4 months.
