Cervico-occipital meningioma in a 5-year-old child: a case report.

AIM: Childhood meningiomas are scarce in clinical practice with an incidence ranging from 0.4 to 4.6% of all pediatric central nervous system (CNS) tumors. Cervico-occipital meningiomas account for 3.7% of childhood meningiomas and are slightly more frequent in male. RESULTS: A 5-year-old female presented with febrile posterior cervico-occipital pain for 3 weeks. She was diagnosed with meningitis and treated for a similar period with adapted antibiotics. The pain persisted even after treatment. Magnetic resonance imaging revealed an enhancing subdural extra medullary mass of the cervico occipital junction, developing around the left vertebral artery. The characteristics of the lesion were strongly suggestive of a neuroma. Surgical removal of the tumor aiming the decompression of the spinal cord and nerve roots was performed with a surprising discovery: The tumor was tightly attached to the dura at the entry of the left vertebral artery. The resection was total and only a thin part close to the artery was left. The pathological findings confirmed the diagnosis of meningothelial meningioma. CONCLUSION: Meningioma should be considered in the differential diagnosis of contrast enhancing subdural extra medullary lesions of the cervico-occipital junction in children.

Pseudotumoral brain lesion as the presenting feature of primary Sjögren's syndrome.

BACKGROUND: The frequency and type of central nervous system involvement in primary Sjögren's syndrome (pSS) remain controversial. Brain magnetic resonance imaging (MRI) abnormalities in pSS are usually discrete hyperintense areas in the white matter. Tumefactive brain lesions have been rarely reported. CASE REPORT: We describe a 31-year-old woman who exhibited transcortical motor aphasia, hemiparesis and partial motor seizures as the initial manifestation of pSS. Brain MRI revealed a large frontoparietal lesion extending into the corpus callosum. The patient had spontaneous recovery and developed sicca symptoms 6 months after onset. Primary SS was diagnosed on the basis of clinical features, abnormal Schirmer test findings, high levels of anti-La/SSB antibodies and positive salivary gland biopsy results. CONCLUSION: The present case suggests that a pseudotumoral brain lesion can occur as an initial symptom of pSS.

Atypical teratoid/rhabdoid tumor of the spine in a 4-year-old girl.

Primary spinal atypical teratoid/rhabdoid tumor is extremely rare. The authors present a case of atypical teratoid/rhabdoid tumor occurring in a 4-year-old girl. Magnetic resonance imaging The authors showed an intramedullary mass extending from the bulbomedullary junction to T1 with leptomeningeal dissemination. The patient died 2 weeks after diagnosis.
