Comparative Study
Optic nerve and its arterial-venous vascularization: an ultrasonologic study in multiple sclerosis patients and healthy controls.
Recent studies suggest that alterations in the cerebrospinal venous system may play a role in multiple sclerosis (MS) and that chronic cerebrospinal venous insufficiency correlates with clinical features of MS patients. ⋯ We found no significant alteration in the arterial-venous vascularization of both affected and unaffected ONr compared with HC. We demonstrated the possibility to detect ONr atrophy in MS patients.

Case Reports
Correlation of sonographic and electrophysiological findings in a patient with multifocal motor neuropathy.
Multifocal motor neuropathy (MMN) is an acquired, immune mediated, and commonly associated with antiganglioside antibodies against GM1 lower motor neuropathy, with an incidence of 1 per 100,000. The usual age of onset is between 20 and 50 years and men appear to be more often affected than women. Patients usually present with multifocal weakness that can be localized to named nerve distributions. ⋯ We draw the attention on the usefulness of ultrasonography for detecting and diagnosing segmental lesions of the peripheral nerves in MMN and other immune mediated neuropathies, especially in cases where a nervous segment cannot be easily explored in terms of inching technique.

Review Meta Analysis
The role of sonolysis and sonothrombolysis in acute ischemic stroke: a systematic review and meta-analysis of randomized controlled trials and case-control studies.
To assess the evidence on the safety and efficacy of sonothrombolysis in acute stroke. ⋯ This novel treatment appears safe and effective. The evidence of microsphere as an enhancement of sonothrombolysis is evolving.

Case Reports
Detection of cerebral hyperperfusion syndrome after carotid endarterectomy with CT perfusion.
We present the case of a 60-year-old female patient, who developed symptomatic internal carotid artery stenosis and subsequently underwent carotid endarterectomy. Four days after an uneventful surgery the patient developed confusion, seizures, and was admitted to the ICU. CT perfusion revealed reduced ispilateral time-to-peak and mean-transient-time and increased cerebral blood volume and cerebral blood flow, confirming the diagnosis of cerebral hyperperfusion syndrome. We thus propose CT perfusion as a diagnostic means for cerebral hyperperfusion syndrome, a syndrome that remains underdiagnosed.

Case Reports
Peripheral nerve sheath tumors. Benign or malignant? The role of MRI and ultrasonography in a case report.
A 31-year-old male patient admitted to another hospital for investigation of a localized painful hump in the medial surface of his left leg. The clinical examination revealed a painful palpable lump in the medial surface of left thigh that was initially thought to be a hematoma due to a history of recent trauma. However, an ultrasound was requested to exclude deep venous thrombosis (DVT). ⋯ A consequent MRI examination confirmed the presence of a fusiform tumor in the anatomic path of the saphenous nerve. This was further confirmed intraoperatively, and pathologically was diagnosed as a malignant peripheral nerve sheath tumor (MPNST). In this present study the role of ultrasonography, the correlation between MRI and ultrasonographic findings are discussed and a review of the literature is presented.
