BACKGROUND Tumors located in the posterior fossa and especially in the middle and upper fourth ventricle are comparatively rare and technically very challenging. For some lesions, the telovelar approach has been shown to be a suitable approach. The unilateral approach is sufficient in most cases of small lesions. However, large fourth ventricle tumors are more problematic since they distort the...

OBJECTIVES Crocin, a constituent of saffron and yellow gardenia, possesses anti-nociceptive effects. In the present study, we investigated the effects of intra-fourth ventricle injection of crocin in a rat model of orofacial pain. The contribution of opioid system was assessed using intra-fourth ventricle injection of naloxone, an opioid receptor antagonist. MATERIALS AND METHODS A guide cann...

Intraspinal subdural lipomas are rare tumors of the spinal canal. Such tumors occur in the thoracic and cervical region; however, extension into the posterior fossa and fourth ventricle is most unusual. We describe two children, an infant and a teenager, with progressive neurologic deficit from such a lipomatous tumor. The lipoma in the infant extended into the lower fourth ventricle and caused...

OBJECTIVE To determine if cranial manipulation is associated with altered sleep latency. Furthermore, we investigated the effects of cranial manipulation on muscle sympathetic nerve activity (MSNA) as a potential mechanism for altered sleep latency. DESIGN Randomized block design with repeated measures. SETTING The Integrative Physiology and Manipulative Medicine Departments, University of ...

Compression of the fourth ventricle (CV4) is a well-known osteopathic procedure, utilized by osteopaths, osteopathic physicians, craniosacral therapists, physical therapists, and manual therapists as part of their healthcare practice based on some evidence suggesting impact on nervous system functions. The main objective of the study was to identify randomized controlled trials (RCTs) assessing...

A 21-year-old man with tuberous sclerosis presented with a 2-day history of progressive nausea, vomiting, ataxia, headache, and mild spasticity. The patient was known to have a large giant-cell astrocytoma occupying the third ventricle, and he had previously had ventriculoperitoneal shunts placed into both lateral ventricles . A multiecho 20FT MR scan was obtained on a 1.5-T unit' with TEs of 2...
