Clear cell meningiomas are an uncommon subtype of meningioma rarely seen in infancy. We report a case of clear cell meningioma in an 8-month-old male infant. He presented at the Lagos University Teaching Hospital, Lagos, Nigeria, in 2015 with persistent vomiting, poor feeding and failure to thrive over a four month period. Generalised hypertonia and hyperreflexia were noted on examination. Computed tomography of the brain revealed a huge largely isodense suprasellar mass with a hypodense core. The tumour, which measured 6 × 5 × 4 cm, enhanced non-uniformly with contrast injection and extended to occlude the third ventricle...

Cervical spine manipulation (CSM) is a commonly spinal manipulative therapies for the relief of cervical spine-related conditions worldwide, but its use remains controversial. CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy.A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour...

An 11-year-old boy presented with progressive walking disturbances. He exhibited severe equinovarus feet that together presented with hyperreflexia of the patellar tendon and extensor plantar, resembling spastic paraplegia or upper neuron disease. He showed mild distal muscle atrophy, as well. We did not observe signs of cognitive impairment, cerebellar signs, or brain magnetic resonance imaging abnormalities. Nerve biopsy showed giant axon swellings filled with neurofilaments. Gene analysis revealed novel compound heterozygous missense mutations in the gigaxonin gene, c...

OBJECTIVE: To determine the cause and course of a novel syndrome with progressive encephalopathy and brain atrophy in children. METHODS: Clinical whole-exome sequencing was performed for global developmental delay and intellectual disability; some patients also had spastic paraparesis and evidence of clinical regression. Six patients were identified with de novo missense mutations in the kinesin gene KIF1A. The predicted functional disruption of these mutations was assessed in silico to compare the calculated conformational flexibility and estimated efficiency of ATP binding to kinesin motor domains of wild-type (WT) versus mutant alleles...

A 16-year-old girl with no prior medical history developed vertigo and nausea following alimentary infection. Neurological examination showed limb and truncal ataxia, opsoclonus, myoclonus, and hyperreflexia. Brain magnetic resonance imaging and cerebrospinal fluid analysis showed no abnormalities. Treatment with i.v. high-dose methylprednisolone and immunoglobulin was started, but this proved ineffective. The clinical course was unusual, so whole-body computed tomography was done to evaluate other differential diagnoses...
