A 71-year-old man with symptomatic basilar artery stenosis refractory to antiplatelet therapy and anticoagulation underwent angioplasty and stenting of the basilar artery. The patient was discharged symptom-free on clodiprogel 75 mg qd and aspirin 325 mg qd. ⋯ Its role in the therapy of symptomatic basilar artery stenosis is not yet defined. Furthermore, the best medical treatment postprocedure is yet to be established.

Acute cerebellitis is one of the main causes of acute cerebellar dysfunction in childhood and may be infectious, postinfectious, or postvaccination. The etiology of acute cerebellitis is usually viral. ⋯ The authors present the clinical and neuroimaging findings of 2 patients presenting with acute cerebellitis. Their magnetic resonance imaging showed hyperintense signal of cerebellar gray matter in T2-weighted sequences, which is a strong indication of a diagnosis of acute cerebellitis.

Misinterpretation of parahippocampal herniation for a posterior fossa tumor: imaging and intraoperative findings.
Tumors of the hippocampal and parahippocampal gyrus are not uncommon, nor are lesions of the cerebellopontine and ambient cisterns. Lesions in these areas include astrocytomas, meningiomas, gangliogliomas, hamartomas, neurilemomas, epidermoids, and dermoids. ⋯ Surgical exploration for biopsy revealed an abnormal posterior fossa anatomy and a parahippocampal herniation into the perimesencephalic cistern. Biopsy confirmed the finding of normal brain.

NC100100 (Sonazoid) is a new perfluorocarbon-based ultrasound contrast agent (UCA) that has not been introduced to transcranial harmonic imaging. ⋯ The new UCA Sonazoid is suitable for displaying brain perfusion. As already observed for other UCAs, gray-scale harmonic imaging with Sonazoid leads to a more homogeneous contrast increase in cerebral parenchyma compared to harmonic power Doppler imaging. Sonazoid produces a moderate shadowing effect, with signal attenuation in the underlying deeper regions of interest.

Ictal and interictal single photon emission computed tomography (SPECT) and ictal electroencephalography (EEG) were studied in a 3-month-old girl with benign familial infantile convulsions (BFIC) to reveal the epileptic focus. There was bilateral diffuse propagation from a left frontal lobe focus on the ictal EEG. Perfusion in the left frontal region was increased on ictal SPECT and decreased on interictal SPECT. Epileptic foci of BFIC showed the same characteristics as foci of symptomatic partial epilepsy.
