During a prospective study conducted at the rehabilitation Center of the physically handicapped persons and at the mother-child Hospital in Bamako, the authors report 50 cases of neuromuscular complications of the quinine intramuscular injection in the child. The scan revealed muscular calcifications in 37 cases (740%), abscesses, in 7 cases (14%) and muscular inflammations in 6 cases (12%). Xray of the affected limb was not systematic: it has been performed in four children in the case of a subjacent bone involment. It showed calcifications in two cases. If muscular abscess is easily diagnosed by clinical exam it is not the case for calcifications. The scan allows to set up a precise mapping of the muscular lesions, to determine their type and size. It also helps the clinicians in their therapeutic attitude. Medical treatment associated with rehabilitation has been carried out in 40 patients (80%) and surgery in 10 patients (20%).
