Cautiously, because of a recent antibiotic exposure, he was managed as a partially treated bacterial meningitis. This case gave the authors the opportunity of a DIAM medical literature review. DIAM is generally benign and reversible without sequelae within 48 hours to a week following cessation of the suspected drug therapy and without any other specific medical treatment. The first hypothesis is supported by the fact that patients with a history of DIAM can tolerate an alternative drug from the same therapeutic class without any adverse effect and that in recurrent cases a shorter and shorter incubation period with lower and lower doses is noticed. The diagnosis of DIAM is difficult and remains one of exclusion.
Diagnosis is easier when recurrent episodes follow drug ingestion.
