Craniolacuna, cribriform skull associated with myelomeningocele and chiari type II malformation: A case report.

Cranial lacuna is a low density radiological image of the cranial vault giving the appearance of beaten copper, the rarefaction zones which are several, producing radiologically a "soap bubble" or "honeycomb" effect. due either to an absence of the internal and external tables or to the absence of a single table or to localized demineralization. They are either physiological or pathological. They are associated with neurological malformations especially hydrocephalus, myelomeningocele and chiari type II malformations. We report the case of a newborn aged one day, admitted for the management of myelomeningocele associated with a chiari type II malformation and a lacunar skull diagnosed postnatally. The newborn is a male, 39 weeks pregnancy, cesarean section. Weight 3500 g, Apgar: 7/10, 8/10. Mother: G6/P5. His clinical examination reveals good skin-mucosal coloration, eupnea, slight axial hypotonia, normal cardiopulmonary auscultation, permeable choanae and esophagus, cranial perimeter at 33 cm, ruptured spina bifida. The skull X-ray reveals a beaten copper appearance of the skull with marked convolutions. The normal chest X-ray. The Abdomino-Pelvic ultrasound finds bilateral uretero-hydronephrosis more marked on the left, with distended bladder and signs of neurogenic bladder. The normal echocardiogram. The brain CT scan reveals a type 2 Chiari malformation, absence of hydrocephalus, The negative infectious assessment, The correct renal assessment, The newborn received neurosurgical management of spina bifida, with a reserved neurological prognosis. This condition is associated with neurological malformations that can have a poor prognosis. Prognosis is reserved in the event of an association with a myelomeningocele because it is dominated by the risk of infection and the dark neurological outcome. The lacunar images resolve spontaneously after 4 to 6 months.
