We studied clinical manifestations of sixteen patients with cerebellar infarcts diagnosed by MRI. In fourteen of them, the stroke developed abruptly with vertigo, which continued for several days. At the early stage of illness, ataxia was obscure. But after vertigo and nausea disappeared, nine cases showed truncal ataxia, while limb ataxia was found in only five. Their vertigo was rotatory and aggravated by head movement. Gaze-evoked nystagmus was observed in only 5 cases. Four patients preferred to take unilateral posture since they experienced less vertigo. The side of their lesions was the lower side of their posture. Limb ataxia was more frequent in SCA-involving cases than in SCA-non involving cases (3 out of 6 vs 2 out of 10, respectively). On the other hand, headache was more frequent in PICA-involving cases than in PICA-non-involving cases (6 out of 11 vs 1 out of 5, respectively). Ataxic gait was seen more in medial branch-involving cases than medial branch non-involving cases (5 out of 6 vs 4 out of 10, respectively). One patient died due to obstructive hydrocephalus.

A 28-year-old woman initially suffered high fever and headache (day 1). Aseptic meningitis was diagnosed on day 3. Limb ataxia, however, appeared on day 7, and external ophthalmoplegia and drowsiness were recognized on day 8. Urinary disturbance and orthostatic hypotension appeared on day 13. Cerebrospinal fluid showed moderately high cell counts(mononuclear cells, 51/microliter; polynuclear cells, 9/microliter). MRI T2-weighted images showed high intensity lesions in the pons and mesencephalon. No serum anti-GQ1b IgG antibody was detected on day 4. Epstein-Barr virus (EBV) viral capsid antigen-IgG antibody was positive, and EBV determined nuclear antigen antibody was seroconverted. EBV-DNA was detected in the CSF by PCR. These findings indicate prior infection by EBV. After intravenous dexamethasone therapy, these symptoms rapidly disappeared. Our patient showed external ophthalmoplegia, ataxia, and disturbance of consciousness, which are the cardinal signs in Bickerstaff's brainstem encephalitis. The time course of her neurological symptoms, the presence of meningitis, and the MRI findings, however, indicated the pathogenesis of acute disseminated encephalomyelitis rather than Bickerstaff's brainstem encephalitis. We diagnosed this patient as a brainstem encephalitis associated with EBV infection.
