Post traumatic leptomeningeal cysts in infancy

Abstract

Post traumatic leptomeningeal cysts (P.T.L.C.) are capsulated liquor collections in the sub-arachnoidal space consequent to skull fractures. They occur typically in infancy and their deceitful onset needs an accurate X-ray follow-up in children with a history of cranial trauma. The authors present six cases of P.T.L.C. encountered in the last three years, recall the mechanism of formation, and stress the importance of standard radiological examination, and computed tomography for early diagnosis.

Posttraumatic Intradiploic Pseudomeningocele: Neuroimaging

“…It is reported in 1-16% of all cases of head injury in children [1][2] . However, its association with an intradiploic pseudomeningocele is very rare.…”

“…The radiological fi ndings in these cases are characterized by an irregular elliptical skull defect involving the inner table with thinned-out outer table, often with tapering ends, the margins being scalloped and sclerotic [2] . The ventricles may communicate directly with an intradiploic cyst or through a porencephalic cyst [1] . The condition needs to be distinguished from intradiploic epidermoid cyst that is, arachnoid cyst of congenital origin [3] .…”

Rapid Evolution of a Growing Skull Fracture after Vacuum Extraction in Case of Fetal Hydrocephalus

“…During the First year of life brain growth progresses most rapidly. In almost all reported cases the cause of injury was a fall from a height or a car accident and it takes several months to years for the clinical picture to evolve [11]. Only 5 cases have been described following traumatic birth: 2 after forceps delivery [12] and 3 after VE [2,3].…”

Early Management of Craniocerebral Injury with Avoidance of Post-Traumatic Leptomeningeal Cyst Formation

“…Although the majority of post-traumatic scalp masses are subgaleal or subperiosteal hematomas, extracranial cerebral tissue and CSF within the subgaleal compartment may mimic these common entities. Those scalp masses accompanied by motor deficits, paresis or posttraumatic seizures, those that fail to resolve within an expected time period, those which change in character when the child strains or cries and those that are pulsatile, most likely represent a disruption of the leptomeninges [4, 5]. …”
