Review Case ReportsPseudotumor cerebri in Lyme disease: a case report and literature review.
Pseudotumor cerebri is an unusual presentation of Lyme disease. The case of an 8-year-old girl with pseudotumor cerebri secondary to acute neuroborreliosis is reported. She presented with acute onset of headache, papilledema, sixth nerve palsy, increased intracranial pressure, and cerebrospinal fluid pleocytosis. ⋯ Twelve reported cases that mostly presented with systemic findings and signs of Lyme disease before development of pseudotumor cerebri were reviewed. We conclude that acute neuroborreliosis can present with pseudotumor cerebri as an initial manifestation. It is important to include Lyme disease in the differential diagnosis of pseudotumor cerebri in an area endemic for Lyme disease.

Visual function in children with merosin-deficient and merosin-positive congenital muscular dystrophy.
This study evaluates whether abnormalities of visual function are present in children with congenital muscular dystrophy and whether these, if present, are associated with merosin status or magnetic resonance imaging (MRI) findings. Twenty children (age range 5-17 years) with a diagnosis of classical congenital muscular dystrophy were assessed on visual acuity, stereopsis, and visual fields and the results compared with merosin status and MRI findings. Visual-evoked potential results were available for 14 of 20 children. ⋯ Unlike the other forms of congenital muscular dystrophy, which are associated with structural brain changes and eye involvement, visual function was always normal in the classical form of congenital muscular dystrophy. Interestingly, visual function was normal also in the group of children with merosin-deficient congenital muscular dystrophy who manifested white matter changes involving the occipital lobes on MRI and abnormal visual evoked potentials. Further studies are needed to specify the nature of the white matter changes observed with MRI and the reason for the dissociation between clinical and neurophysiologic findings.
