A 4 year old boy presents to the emergency department with balance problems. He had been previously healthy, but his walking has worsened progressively for the past 2 days, with staggering and lurching.
On PE, the boy is cooperative and alert. His muscles are not tender, and his joints are not red, swollen or tender. His vision seems functionally normal, but there is end-gaze nystagmus in all directions. When sitting independently, his head and trunk bob. His strength appears normal, and his reflexes are normal. When asked to stand with his hands outstretched, a symmetric tremor is evident, and worsens as he approaches this target on finger-to-nose testing. His gait is broad-based. A urine toxicology screen reveals normal results. Brain magnetic resonance imaging shows no tumors or other gray or white matter lesions. Lumbar puncture shows 3 WBCs, 2 RBCs, protein 20, glucose 50.
-Cerebellar findings on exam: Lateral end gaze nystagmus, dysmetria, ataxia, titubation.
-Subacute onset with normal mental status suggests acute cerebellar ataxia
-Usually acquired after infection or immunization
-MRI shows lesion
-Regarding other choices:
A. Intravenous steroids significantly reduce recurrence risk: They don't
B. Neuroblastoma is a common cause of these symptoms: not as common
C. Repeat lumbar puncture is needed in 2 days: no new information
E. Symptoms usually resolve after antibiotic treatment: Not a primary infectious process
