ABSTRACT
A 73-year-old Japanese man with diabetic complications presented with involuntary lip movements and long-lasting hiccups after developing zoster rash. Magnetic resonance imaging revealed lesions involving the medial temporal lobe and C1 level of the spinal cord. Varicella-zoster virus (VZV) encephalomyelitis was diagnosed. We considered attributing the orofacial dyskinesia, a very rare symptom of VZV central nervous system (CNS) complications, to the temporal lobe lesion. Although the culprit lesion for the hiccups was unclear, further examinations may have clarified this issue. As immunocompromised patients with herpes zoster may develop CNS complications with a wide variety of symptoms, special care is needed.

A Japanese man in his 60s on medication for chronic lymphocytic leukemia presented with progressive, multifocal neurological manifestations. Magnetic resonance imaging showed a small, solitary region of brainstem involvement. Sensitive real-time polymerase chain reaction testing detected a small amount of JC virus (JCV) DNA (170 copies/mL) with pathogenic mutation in cerebrospinal fluid. We diagnosed the patient with progressive multifocal leukoencephalopathy (PML). The small PML lesion may have caused multifocal neurological symptoms because of its focal brainstem involvement. This case contributes to knowledge regarding the diagnosis and treatment of brainstem PML in the context of hematologic malignancies and other underlying diseases.

Legionella is a rare cause of mild encephalitis/encephalopathy with reversible splenial lesion, which should be considered in patients with risk factors. Brain magnetic resonance imaging (MRI) and legionella urinary antigen test can help the diagnosis since cerebrospinal fluid (CSF) can be normal.
