ABSTRACT
BACKGROUND: Despite new techniques for the treatment of cerebral aneurysms, the percentage of aneurysm remnants after surgical intervention seems to be relatively constant. The objective of this study was to assess angiographic and epidemiological features associated with aneurysm remnants after microsurgical clipping. METHODS: This study was conducted from February 2009 to August 2012 on a series of 90 patients with 105 aneurysms referred to the Santa Casa of Belo Horizonte who were surgically treated and angiographically controlled. RESULTS: Surgical clipping was considered incomplete in 13.3% of the aneurysms. The mean age of cases with an aneurysm remnant was 57.5 years, whereas the mean age without aneurysm remnant was 49.7 years (P = 0.02). Aneurysm remnants were detected more frequently on the internal carotid artery, nevertheless, no statistically significant differences were verified when comparing the locations. Aneurysm size in the preoperative angiography verified that the mean size of aneurysms operated was 6.56 mm, such that in cases showing a postoperative remnant, the mean size was 9.7 mm and in cases with complete clipping it was 6.08 mm (P = 0.02). Postoperative angiography showed that, in cases with residual aneurysm, the number of clips used was higher - a mean of 1.8 for complete clipping and 3.1 for incomplete clipping (P < 0.001). CONCLUSIONS: Aneurysm size and patient age showed significant correlations with residual intracranial aneurysm. The mean number of clips used was higher in cases with incomplete occlusion.
ABSTRACT
We describe the case of a 35 years old man with a nonspecific complaint of a slow growing solid mass in the frontal region. Radiological exams evidenced two more lesions : in the superior and lateral walls of the orbit. Treated with total excision of the lesions and a cranioplastic procedure at the same act, with favorable outcome. Microscopic findings suggested giant cell tumor in the three lesions that was confirmed by immunohistochemical examination.

Descrevemos o caso de homem de 35 anos, com história de lesão endurecida de crescimento progressivo na região frontal direita. Exames radiológicos evidenciaram duas outras lesões: uma na parede superior e outra na parede lateral da órbita direita. Submetido a exérese total das lesões com margem de segurança e cranioplastia no mesmo tempo cirúrgico. O exame anatomo patológico sugeriu tumor de células gigantes nas três lesões, diagnóstico confirmado pela imuno-histoquímica.
