The authors present a rare case of cavernous angioma mimicking a meningioma in a 58-year-old man who presented with a headache and dizziness. There were no neurological deficits or other neurological symptoms or signs. An extra-axial mass lesion thought to be associated with diffusely well-enhanced falx in the postcontrast sections was noted in the posterior interhemispheric fissure near the posterior part of the corpus callosum splenium. Extra-axial cavernous angiomas (cavernomas) are extremely rare lesions. They most commonly occur in the parenchyma but have been occasionally reported to arise from the dura matter. Dural cavernous angiomas arise from dural sinuses, falx cerebri, tentorium cerebelli, cranial base dura, or internal auditory canal dura and convexity. Parenchymal cavernous angiomas classically have a ring of hemosiderin surrounding the lesions observed on magnetic resonance imaging, but dural cavernous angiomas do not display the same magnetic resonance imaging characteristics and occasionally exhibit a dural tail sign due to which they can often be misdiagnosed as meningiomas.
Basilar invagination, Platibasi, increased tentorium angle, and posterior fossa hypoplasia are the anomalies associated with Chiari malformation. When Chiari is symptomatic; tonsillary ectopenia appears to be a definitive criterion for diagnosis and treatment, the detection of additional anomaly may alter the surgical outcome. The aim of this study is to investigate the relationship between tonsillar ectopia and other anomalies. The authors retrospectively reviewed 31 cases which had Chiari Malformation at our Hospital. There were 8 men (25.8%) and 23 female (74.2%). Average age of the samples is 37.93 ± 12.93 years. Seventeen patients (54.8%) had tonsillar ectopia 0 to 5 mm, 14 patients had tonsillar ectopia over 5 mm. Seven patients had syrinx (22.6%), 2 patients had mild hydrocephalus (6.5%). Six patients had surgery for the treatment. The mean length of the clivus was 39.3 mm, supraoksiput length was 40.4 mm, cerebellar hemisphere length was 61.08 mm, Mc Rae line was 33.14 mm, Twinning Line was 79.4mm, and Tentorium-Twinning line angle was 40.35°. There was no significant difference between Tonsillar ectopia, syrinks, and hydrocephalus. Basilar invagination had relationship between platibasi (6 patients had platibasi according to 2 mm criteria, 2 patients had platibasi according to 5 mm criteria (P < 0.05). Patients with syrinx had relationship between Chamberlain line (P < 0.05). In the authors’ study, although there was no statistically significant difference between the tonsillary ectopia and the criteria of these anomalies, the relationship between basilar invagination and platibasi was significant.
Objective: To investigate mortality in patients undergoing surgical treatment for spontaneous intracranial hemorrhage (sICH) and to identify the predictive factors. Materials and Methods: The medical records of 164 patients with sICH who underwent surgery at two institutions between 2010 and 2017 were retrospectively examined and analyzed. Results: Among 164 patients who received surgical treatment, 83 (50.6%) were women and 81 (49.4%) were men. The mean patient age was 56±14.54 years. Of all patients, 109 (66.4%) had hypertension. Hematoma was intraparenchymal in 69 (42.1%) patients, thalamic in 33 (20.1%), intraventricular in 33 (20.1%), and cerebellar in 29 (17.7%) patients. The mortality rate among patients who underwent surgery within the first 8 h of hematoma occurrence was 55.4%; this rate was 73% among those who underwent surgery 8-24 h after diagnosis, and 72.7% among those who underwent surgery 24-48 h after diagnosis. Conclusion: Prognosis and mortality associated with sICH are usually affected by patient age, hematoma location and volume, intraventricular hemorrhage, and patient's initial neurologic status. We found no significant relationship between surgical treatment 8 h after hemorrhage and mortality. There are still discussions about the indications of surgical treatment in intracranial hematomas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
