This case report describes a 63-year-old man referred with right-sided glossopharyngeal neuralgia. Magnetic resonance imaging (MRI) demonstrated asymmetry of the PICA vessels. A microvascular decompression was performed and complete remission of symptoms followed. After 14 months the neuralgia recurred, this time accompanied by sinus bradycardia/sinus arrest during attacks causing discomfort and syncopes. An MRI now demonstrated an arterial loop at the site of the vagoglossopharyngeal complex leaving the brainstem. After another microvascular decompression, complete remission of symptoms was observed.
Cerebellar mutism syndrome (CMS) is rarely described in adults; however, data on self-assessed linguistic complications after posterior fossa surgery do not exist.Through a prospective single-center study, data on 59 tumor operations in the posterior fossa were collected preoperatively as well as 1 week and 1 month postoperatively. Data on self-assessed problems in 5 CMS-related domains, CMS scores, and neurology as well as surgical procedure and complications were obtained.Data on CMS-related complications were obtained on 56 of the 59 operations. None was found to have CMS according to the CMS score. Within each of the 5 domains, at least 9 operations (16%) were followed by development or worsening of self-assessed CMS-related complications. Self-assessed complications were found to be most frequent after primary tumor surgeries, although they were significant only for speech and motor complications (P value = 0.01 and 0.02). Speech and language complications occurred more frequently in midline tumors compared with lateral tumors (40% vs. 7%; P = 0.004). Surgical complications were similar to other studies.We propose that speech and language problems in adults undergoing surgery in the posterior fossa occur more frequently than previously assumed. Some of the self-assessed complications might reflect components of the cerebellar cognitive affective syndrome. Our findings are consistent with the fact that midline location of the tumor is one of the few known risk factors for CMS in children. Thus, the cerebellar midline seems to be a vulnerable region for speech and language complications also in adults.
This review states the reasons for considering screening for intracranial aneurysms in Denmark: if patients have two first-degree relatives with intracranial aneurysms, are 30-70 years old, do not have competing disorders, which could significantly shorten life expectancy, and subsequently in patients with autosomal dominant kidney disease and a family history of subarachnoid haemorrhage. MR angiography should be the imaging study of choice, unless contraindicated. Generally, the ethical consequences ought to be considered before carrying out screening.
