Early reappearance of disappeared ruptured small aneurysm with concomitant vertebral artery dissection.

Thrombosis of a previously ruptured intracranial aneurysm is a frequent event and it most commonly occurs in large or giant aneurysms. We present a dynamic short-term follow-up and management of thrombosis in a ruptured small posterior inferior cerebellar artery aneurysm with concomitant vertebral artery dissection (VAD). Clinical and radiological follow-up findings and reviewed literature on thrombosis of small ruptured aneurysms are the focus of this presentation. Early reappearance of a disappeared ruptured small cerebral aneurysm with a concomitant VAD may be attributed to the controlled ovarian hyperstimulation phase of in vitro fertilization and prolonged use of oral contraceptive pills.

Cerebral proliferative angiopathy with tumor-like hemorrhage: A case report and literature review.

Cerebral proliferative angiopathy (CPA) is defined as a rare vascular disorder, characterized by diffuse arterial proliferation and distinctive angiogenetic features. Complication with hemorrhage is exceedingly rare, but once the bleeding occurs, the chance of re-bleeding is increased. Here we report a case of a patient with CPA complicated with bleeding and re-bleeding, and imaging findings mimicking a brain tumor, which has not been reported in the literature so far.

An unusual complication of atrial fibrillation ablation: case report.

The authors report a complication of catheter ablation that, to their knowledge, has never been previously reported. A 63-year-old man had undergone successful transvenous catheter thermoablation for atrial fibrillation. The patient remained well until 3 days prior to further admission when he noticed itching in the right frontal area of his scalp. On palpating his scalp, he discovered a metallic body projecting out of it and he proceeded to extract 20 cm of wire from his head. The following day a progressive left hemiplegia developed, and the patient experienced a deteriorating level of consciousness. A CT scan of the brain showed a right frontotemporal intraparenchymal hemorrhage and revealed a metallic structure in the middle of the hematoma. The hematoma was evacuated and a decompressive craniotomy was performed. The guidewire was identified, but it was only possible to extract part of it. It was covered by fibrous tissue, secondary to inflammatory reaction. To the authors' knowledge, this is the first report of guidewire-induced brain hemorrhage. The guidewire apparently had not been removed and had spontaneously migrated from the heart to the brain and beyond to the scalp where it then exited the patient's head. The patient had been well before he attempted to pull out the wire. Earlier identification of the iatrogenic complication of a retained guidewire might have prevented the fatal outcome in this case.

Bathing epilepsy: report of three caucasian cases.

INTRODUCTION: Bathing epilepsy is a specific type of reflex epilepsy triggered by domestic bathing in water. It is a geographically specific epilepsy syndrome that is more prevalent in India Cases in Caucasian population are very rarely reported. These cases share many similar clinical features and a similar prognosis to the Indian cases. CASE REPORT: We describe three cases of bathing epilepsy in Albanian population; two cases with well controlled seizures and one with drug-resistant seizures.

Glioblastoma after AVM radiosurgery. Case report and review of the literature.

BACKGROUND: Stereotactic radiosurgery (SRS) is considered to be a relatively safe procedure in cerebral arteriovenous malformation management. There are very few reported cases of SRS-associated/induced malignancies. METHODS: We show the case of a 21-year-old female who presented with a 21-mm(3) ruptured AVM in the right mesial frontocallosal region. Embolization and/or radiosurgery was proposed. She preferred radiosurgery. The AVM was treated with CyberKnife(®) SRS. RESULTS: She presented behavior changes 6 years after SRS. MRI showed a right subcortical frontal lesion with increased perfusion, more consistent with high-grade glioma. The lesion's center was within the irradiated region of the previous SRS, having received an estimated radiation dose of 4 Gy. Pathological examination noted a hypercellular tumor showing astrocytic tumor cells with moderate pleomorphism in a fibrillary background, endothelial proliferation, and tumor necrosis surrounded by perinecrotic pseudopalisades. Numerous mitotic figures were seen. The appearances were those of glioblastoma, WHO grade IV, with neuronal differentiation. SRS-associated/-induced GBM after treatment of a large AM is exceptional. SRS-associated/-induced malignancies are mostly GBMs and occur on average after a latency of 9.4 years, within very low-dose peripheral regions as well as the full-dose regions; 33.3 % of patients were under 20 years at the time of SRS, and in 66 % the lesion treated was a vascular pathology. CONCLUSION: Although it is unlikely that the risk of radiation-induced cancer will change the current standard of practice, patients must be warned of this potential possibility before treatment.
