Abstract. Subarachnoid hemorrhage from an intracranial aneurysm during pregnancy is a rare complication with high maternal and fetal morbidity-mortality. We report three cases of ruptured intracranial aneurysms during pregnancy, treated by the minimal invasive endovascular approach.

Behçets disease (BD) is a well-known multisystem inflammatory disorder of unknown etiology. Aneurysms of the cerebral arteries are not commonly described in patients with BD. There are few cases of intracranial aneurysms with BD reported in the literature. In this study, we report endovascular treatment of BD-related ruptured intracranial aneurysms in two cases, and present a wide literature review of intracranial arterial aneurysms related to BD.

Adenosine deaminase 2 (ADA2) deficiency due to CECR1 mutations is a recently defined disorder that involves systemic inflammation and vasculopathy often associated with polyarteritis nodosa. We report on a 5-year-old girl with a severe vasculopathy who carried two novel mutations in CECR1. Conclusion: Identification of CECR1 mutations in patients with vasculopathy may lead to earlier diagnosis of ADA2 deficiency.

Abstract. There are very few reported cases of Erdheim-Chester disease that document involvement of dura at the level of the spinal cord. Among these reports, we know of no publication that includes detailed MRI findings. To the best of our knowledge, the case presented here is the first published report of this specific manifestation of Erdheim-Chester disease that includes detailed MRI findings in addition to the related history. Spinal manifestations of Erdheim-Chester disease in our patient were at the dorsal and lumbar levels (T1–T6 and T12–T11 respectively). Both epidural and subdural linear large masses were present, causing spinal cord compression at the dorsal level and epidural thickening at the lumbar level.

We report the results of a retrospective analysis of radiological and clinical findings in 45 cases of midbrain–hindbrain anomalies and review recent advances in embryology and molecular neurogenetics. Among 45 patients with midbrain–hindbrain malformations, 16 cases of molar tooth malformation, 12 of cerebellar hypoplasia, ten of posterior fossa cyst and cerebellar vermian hypoplasia, three of rhombencephalosynapsis, two of Fukuyama congenital muscular dystrophy and two cases of isolated cerebellar dysplasia were identified. Twenty-six patients presented with motor-mental retardation, which was the most common clinical finding. Eleven patients were born to consanguineous parents. The correct diagnosis of cerebellar malformation is important for determining prognosis, the risk of recurrence and the need for genetic counselling. Integrated classification of malformations based on morphology, embryology and molecular neurogenetics may be useful.

Aim: The authors present their experience and the clinical results in decompressive craniectomy (DC) in patients with vasospasm after aneurysmal subarachnoid hemorrhage (SAH). Materials and Methods: Between 2002 and 2010, six patients underwent DC due to cerebral infarct and edema secondary to vasospasm after aneurysmal SAH. Four patients were male, and two were female. The age of patients ranged between 33 and 60 (mean: 47,6 ± 11,4). The follow up period ranged between 12 to 104 months (mean: 47,6 ± 36,6). The SAH grading according World Federation of Neurosurgeons (WFNS) score ranged between 3 to 5. Results: Last documented modified Rankin Score (mRS) ranged between 2 to 6. One patient died in the following year after decompression due to pneumonia and sepsis. Two patients had moderate disability (mRS of 4) and three patients continue their life with minimal deficit and no major dependency (mRS score 2 and 3). Conclusion: DC can be a life-saving procedure which provides a better outcome in patients with cerebral infarction secondary to vasospasm and SAH. However, the small number of the patients in this study is the main limitation of the accuracy of the results, and more studies with larger numbers are required to evaluate the efficiency of DC in this group of patients.

A 23-year-old woman with the medical history of homocystinuria that had been diagnosed at the age of 14 has been non-responsive to treatment. The patient presented with the symptoms of dysphonia, dysarthria and severe dystonia of the neck and left extremities. Blood and urine biochemistry revealed high levels of homocystine. Brain magnetic resonance imaging was normal with no detectable pathologies. Medical treatment strategies were used and repeated injections of botulinum toxin A were administered, but the symptoms showed no significant improvement. The patient was then operated, and deep brain stimulators targeting the bilateral globus pallidus internus were implanted. After the activation of the electrodes, dystonia symptoms showed a remarkable improvement. Good outcome was documented during the follow-up period of 7 months. To our best knowledge, this is the first reported case of homocystinuria-related dystonia symptoms that were successfully treated with deep brain stimulation.

Cavernous hemangioma (CH) is a benign vascular malformation. Intracranial CH is generally localized as an intracranial-intraaxial and responsible for 5-13% of all intracranial vascular malformations. Intracranial-extraaxial CHs are rare rather than intracranial-intraaxial CHs. Clinical findings, imaging characteristics, and surgical approach of extraaxial CHs are rather different than intraaxial CHs. Diagnosing cavernous sinus CH preoperatively is very important, but its radiological differential diagnosis is quite difficult. In this study, we present magnetic resonance imaging findings of a 48-year-old male who was considered preoperatively to have meningioma but was diagnosed with cavernous sinus CH during surgery by pathological examination.

A 5-year-old child had a medical history of epilepsy and a newly presented mental retardation with a life-threatening dystonic storm. Neuroimagings showed bilateral calcification of the pallidum. Several treatment modalities were performed, but the symptoms showed no significant improvement. The patient was operated on in order to place a deep brain stimulation (DBS) targeting bilateral globus pallidum internus (GPi). The dystonia showed a remarkable improvement after surgery, with 81% reduction of dystonia severity after 15 months. To our best knowledge, this is the youngest patient mentioned in the literature to be treated with DBS, which was also life-saving in this case.

We report a case of ischemia of the auricle and acute parotitis that developed following embolization for epistaxis. A 53‐year‐old male was previously conservatively treated for epistaxis with bilateral posterior nasal packing due to hypertension. As the bleeding, continued the patient underwent bilateral embolization of the internal maxillary arteries. The bleeding was controlled but the patient developed acute ischemia of the ipsilateral parotid gland and the auricle that regressed with medical treatment. Laryngoscope, 2012
