We investigated how many contrast-transcranial Doppler (c-TCD) examinations should be performed on different days in patients with acute stroke. ⋯ c-TCD examinations should be performed on at least two different days to assess the prevalence of RLS.

High core body temperatures have been shown to selectively damage the cerebellum and basal ganglia in malignant hyperthermia, but involvement of both areas in neuroleptic malignant syndrome (NMS) has not been described. ⋯ Both the basal ganglia and cerebellum can be injured selectively in NMS.

We describe a rare case of a patient with left frontotemporal gliosarcoma, which metastasized through the cerebrospinal fluid (CSF) to the leptomeninges and pachymeninges. Pathologically confirmed, magnetic resonance imaging-visible leptomeningeal spread of gliosarcoma via the CSF has not been previously reported.

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently defined inflammatory central nervous system disorder responsive to steroids with characteristic magnetic resonance imaging (MRI) features. We report a 69-year-old man presenting with gait ataxia with the characteristic MRI features of CLIPPERS and describe the clinical, MRI, and magnetic resonance spectroscopy (MRS) follow-up after treatment with glucocorticosteroids. Brain and spine MRI showed punctate enhancement peppering the brainstem, cerebellar peduncles, and upper cervical cord. ⋯ Treatment with steroids led to rapid clinical improvement. Repeat MRI and MRS showed complete resolution of gadolinium-enhancing lesions and recovery of NAA/Cr levels in the pons and thalami. After 1 month of tapering oral steroids, weekly oral methotrexate was started and the patient has remained stable for the past 6 months.

Hyperpneumatization of the temporal bone with extension into the occipital bone and even the parietal bones is a rare condition. We report a case in which the patient suffered periodically from a palpable mass in the parietal-occipital region which originated from extensive occipital bone pneumatization. Computed tomography examination revealed extensive temporal and occipital pneumatization and subperiosteal pneumatoceles, which was corrected by surgery.
