Abstract -Introduction:We report the case of an infant (4 months) hospitalized in a neurological intensive care unit for seizures from unknown aetiology. Patient and method: During the stay in hospital, were observed repeatedly, on six times, a very sudden drowsiness, abnormal motions and a hypotonia.The feeding tube brought back a thick purple liquid. A toxicological screening (GC-MS and HPLC-DAD) was performed on a sample of this liquid. Other samples were collected from blood, urine, gastric liquid, administered drugs, milk from the feeding bottle and hair. Hairs were tested by LC-MS/MS in search of psychotropic drugs.
