Objective The assessment of the posterior pharyngeal vasculature In velocardiofacial syndrome has been traditionally based on endoscopic visualization of pulsations or conventional angiography. This case report describes the utility of presurgical imaging with magnetic resonance angiography (MRA) prior to performing pharyngoplasty. Conclusion The use of the MRA data presurgically is an effective way to prevent bleeding complications during pharyngoplasty.

Abstract OBJECTIVE AND IMPORTANCE: The present case report is the first one to report a bilateral anastomotic artery between the internal carotid artery and the anterior communicating artery in the presence of a bilateral A1 segment, fenestrated anterior communicating artery (AComA), and associated aneurysm of the AComA, which was discovered by magnetic resonance angiography and treated surgically. CLINICAL PRESENTATION: A 38-year-old man who was previously in good health experienced a sudden onset of nuchal headache, vomiting, and confusion. Computed tomography revealed a subarachnoid hemorrhage. Magnetic resonance angiography and four-vessel angiography documented an aneurysm of the AComA and two anastomotic vessels of common origin with the ophthalmic artery, between the internal carotid artery and AComA. INTERVENTION: A fenestrated clip, introduced by a left pterional craniotomy, leaving in its loop the left A1 segment, sparing the perforating and hypothalamic arteries, excluded the aneurysm. CONCLUSION: The postoperative course was uneventful, with complete recovery. Follow-up angiograms documented the successful exclusion of the aneurysm. Defining this particular internal carotid-anterior cerebral artery anastomosis as an infraoptic anterior cerebral artery is not appropriate because there is already an A1 segment in its habitual localization. Therefore, it is also thought that, embryologically, this anomaly is not a misplaced A1 segment but the persistence of an embryological vessel such as the variation of the primitive prechiasmatic arterial anastomosis. The favorable outcome for our patient suggests that surgical treatment may be appropriate for many patients with this anomaly because it provides a complete and definitive occlusion of the aneurysm.

✓ Whether a diagnosis of moyamoya disease is justified in patients with typical angiographic evidence of moyamoya disease unilaterally and normal angiographic findings contralaterally remains controversial. In this study the authors analyzed longitudinal angiographic change, familial occurrence, and basic fibroblast growth factor (bFGF) concentration in the cerebrospinal fluid (CSF) of patients with “unilateral” moyamoya disease. Over a 10-year period, 10 cases of unilateral moyamoya disease were followed using conventional angiography or magnetic resonance angiography. Basic FGF in CSF, obtained from the subarachnoid space of the cerebral cortex during revascularization surgery, was measured in five cases. Among the 10 cases of unilateral moyamoya disease, only one pediatric case showed obvious signs of progression to typical bilateral disease. The other nine cases (including six adults and three children) remained stable throughout follow-up radiological examinations (magnetic resonance angiography) with a mean observation period of 3.5 years. There was no familial occurrence in these cases of unilateral moyamoya disease. Levels of bFGF, which are high in typical moyamoya disease, were low in these patients. The progression from unilateral moyamoya disease to the typical bilateral form of the disease appears to be infrequent. The low levels of bFGF in the CSF of these patients and the lack of familial occurrence strongly suggest that most cases of unilateral moyamoya disease, especially those found in adults, are distinct from typical bilateral moyamoya disease.

Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by acute thunderclap headache, evidence of vasoconstriction in conventional angiography or magnetic resonance angiography and reversibility of these phenomena within 12 weeks. Some triggering factors, for example drugs such as selective serotonin reuptake inhibitors, sumatriptan, tacrolimus, cyclophosphamide and cocaine, or states such as pregnancy, puerperium or migraine have been described. We describe the case of a 29-year-old woman with RCVS associated with fingolimod three months after childbirth. This case represents the first report of RCVS in fingolimod treatment.
