Facial Dysmorphia

Acalvaria is a rare and lethal congenital malformation characterized by the absence of the cranial vault bones, dura mater and associated muscles with complete cranial content. We report a 5-year-old Malian girl seen at 20 months old for facial dysmorphia, hemiparesis, and a cranial bone defect that improved progressively.

The Brain

Malignant lymphoma of the head rarely arises outside of the brain parenchyma as primary cranial vault lymphoma (PCVL). A case of PCVL that invaded from subcutaneous tissue into the brain, passing through the skull, and occurred after mild head trauma is reported along with a review of the literature. The patient was a 75-year-old man with decreased activity. One month before his visit to our hospital, he bruised the left frontal area of his head. Magnetic resonance imaging showed homogeneously enhanced tumors with contrast media in the subcutaneous tissue corresponding to the head impact area and the cerebral parenchyma, but no obvious abnormal findings in the skull. A biopsy with craniotomy was performed under general anesthesia. The pathological diagnosis was diffuse large B-cell lymphoma. On histological examination, tumor cells grew aggressively under the skin. Tumor cells invaded along the emissary vein into the external table without remarkable bone destruction and extended across the skull through the Haversian canals in the diploe. Tumor cells were found only at the perivascular areas in the dura mater and extended into the brain parenchyma. Considering the history of head trauma and the neuroimaging and histological findings, the PCVL in the present case arose primarily under the skin, passed though the skull and dura mater, and invaded along vessels and reached the brain.

Introduction The extra dural hematoma is a blood collection between the cranial vault and the dura mater. It is a neurosurgical emergency whose statistical data are poorly known in the Republic of Benin. Objective The aims of this study are to assess epidemiology, therapeutic and outcome of traumatic extra dural hematomas for children admitted to the surgical department of CHUD-B/A from 2012 to 2017. Methods This was a cross-sectional, descriptive and retrospective study over a period from January 1st, 2012 to December 31st, 2017. Results One hundred and seventy-eight cases of children aged between 0-15 years were examined for brain traumatic injury. Twenty-seven 27 (15.2%) cases of extra dural hematomas were retained. The most represented age group was between 11-15 years with a frequency of 42.1%. The male sex was more represented (78.9%). Road traffic accidents were the main aetiology (57.9%). 52.6% had a mild head injury, 26.3% had a moderate head injury and 21.1% had a severe head injury. On brain scan the frequently observed location was temporo-parietal (31.6%). Acute anemia was observed in 16 children. Seventeen children were operated on. The operation involved evacuation of extra dural hematoma by cranial bone flap with suspension of the dura mater. There were no deaths. Conclusion The availability of brain CT makes the diagnosis of extra dural hematoma easier. Its management is neurosurgical with a favourable post-operative evolution in all cases in this series.

Average Development

Acalvaria is a rare congenital malformation characterized by an absence of skin and skull. The authors describe a newborn at an estimated 38 weeks gestational age who was delivered via cesarean section from a 32-year-old mother. Upon delivery, the child was noted to have a frontal encephalocele and an absence of calvaria including skull and skin overlying the brain. A thin membrane representing dura mater was overlying the cortical tissue. After multiple craniofacial operations, including repair of the encephalocele and application of cultured keratinocytes over the rostral defect, the patient demonstrated significant closure of the calvarial defect and was alive at an age of more than 17 months with near-average development.
