Acute methotrexate toxicity rarely presents as medical emergency in form of multiorgan failure. Acute pneumonitis following low-dose methotrexate is rarely reported in literature. It is important to recognize this, as the drug must be discontinued immediately and rescue measures in form of folinic acid and hydration instituted promptly.
