[Osteogenesis imperfecta diagnoses early, apropos of a case at the Yalgadou Ouédraogo National Hospital Center of Ouagadougou].

Osteogenesis imperfecta which represents a family tragedy for parents, a curiosity for physicians and radiologists, constitutes a real constitutional osteoporosis, usually rare with dominant autosomic transmission. Authors report a case of a 37 week amenorrhea living foetus, presenting an osteogenesis imperfecta. This affection, with early in utero manifestations, has a bad prognosis (baby deceased 72 hours after birth). Diagnosis was suspected at echography and conformed by x-rays investigations. The new born got also clinical and pathological examinations. Authors emphasize the unusualness and the gravity of these early clinical features. They insist on doing echography and radiography for the location of osseous and visceral lesions before and afterbirth.
