No full textTo evaluate clinical characteristics and outcome of myasthenia gravis (MG) in aged patients (>60yrs), we retrospectively reviewed a continuous series of 122 myasthenic patients observed from January 1968 through December 1994. Patients with congenital, neonatal, of penicillamine-induced myasthenia were excluded. Twenty-five subjects (20%) were >60yrs. The male/female ratio was 3.2; 20% of patients had an ocular form and 86% were seropositive. Mediastinum CT scan revealed thymic changes in 14%. During the first five years of disease, 60% of patients with ocular form progressed towards a generalized form and 15% had clinical relapses. At the time of their last visit, 40% of patients were asymptomatic and 60% had improved on medication. No patient died because of myasthenia-related causes. This study shows that MG in aged patients is characterized by prevalence in males, low frequency of ocular forms, low frequency of positive mediastinum CT which suggests low frequency of thymomas, high frequency of progression of ocular forms, and good response to corticosteroid therapy

Twenty-five subjects (20%) were >60 yrs. The male/female ratio was 3:2; 20% of patients had an ocular form and 86% had AchR antibodies. Mediastinum CT scan revealed thymic changes in 14%.

A slowly growing benign brain mass
No full textA 33-year-old woman presented with occasional
mild nonlateralized headache. Examination was normal.
Brain MRI revealed a neuroglial cyst in the right
hemisphere which expanded slowly but relentlessly
over subsequent years (figure 1; figure e-1 on the
Neurology® Web site at www.neurology.org). At the
last MRI, the lesion produced considerable mass effect,
but the patient’s examination was still normal.
She refused surgery. Neuroglial cysts are uncommon
congenital lesions.1,2 Unlike the more common
arachnoid cysts, they are located within brain parenchyma
and arise from remnants of embryonic neural
tube elements, sequestered in the developing
white matter. Most neuroglial cysts remain stable
in size. Minimal but persistent intracystic CSF secretion
may explain cyst expansion over time
