Abstract The relationship between the results of early operation for ruptured intracranial aneurysms (72 cases) and the preoperative computed tomographic (CT) findings was studied. There was a correlation among the surgical results, the development of symptomatic vasospasm, and high density on the preoperative CT scan, particularly the presence of a localized, thick layer in the subarachnoid space. However, no relationship was found between the occurrence of ventricular enlargement and the preoperative CT findings. Cisternal or ventricular drainage might contribute to an uncomplicated postoperative course for patients with severe subarachnoid clot shown on the preoperative CT scan.

Abstract The incidence of hydrocephalus and vasospasm and the relationship between them were analyzed retrospectively in 87 patients with subarachnoid hemorrhage from ruptured intracranial aneurysms. Sixty-seven per cent of the patients showed ventricular enlargement on a computed tomographic scan done within 30 days of the hemorrhage; in patients whose first scan was done within 3 days of the hemorrhage, 63% seemed to have ventricular enlargement by a neuroradiologist's interpretation. Shunts were required in 14% of the patients because of delayed neurological deterioration or enlarging ventricles; 3% required ventriculostomy shortly after admission. Seventy-four per cent of the patients had angiographic spasm on an angiogram done within the first 30 days after hemorrhage. Sixty-two per cent of the patients had both hydrocephalus and vasospasm: 22% had neither. Five per cent had hydrocephalus, but no spasm; 11% had spasm. but no hydrocephalus. Hydrocephalus and vasospasm were significantly associated (P < 0.01, x2). These data document a high incidence of mild ventricular enlargement and angiographic vasospasm after subarachnoid hemorrhage. They also emphasize that these two sequelae of subarachnoid hemorrhage are closely linked, probably by the presence of blood in the basal cisterns obstructing cerebrospinal fluid flow and surrounding arteries there.

OBJECT Intraprocedural rerupture (IPR) of intracranial aneurysms during coil embolization is associated with significant periprocedural disability and death. However, whether this morbidity and mortality are secondary to an increased risk of vasospasm and hydrocephalus is unknown. The authors undertook this study to determine the in-hospital and long-term neurological outcomes for patients with aneurysmal subarachnoid hemorrhage (SAH) treated with coil embolization who suffer aneurysm rerupture during treatment. METHODS The records of 156 patients admitted with SAH from previously untreated, ruptured, intracranial aneurysms and treated with endovascular coiling between January 2007 and January 2014 were retrospectively reviewed. Twelve patients (7.7%) experienced IPR during coil embolization. RESULTS Compared with the cohort of patients with uncomplicated coil embolization procedures, patients with aneurysm rerupture were more likely to require external ventricular drain (EVD) placement (91.7% vs 58.3%, p = 0.02) and postprocedural EVD placement (36.4% vs 7.1%, p = 0.01), to undergo permanent ventriculoperitoneal shunt placement (50.0% vs 18.8%, p = 0.02), to develop symptomatic vasospasm (50.0% vs 18.1%, p = 0.02), and to have longer lengths of hospital stay (median 21.5 days vs 15.0 days, p = 0.04). Admission Hunt and Hess, modified Fisher, and Barrow Neurological Institute grades did not differ between the 2 cohorts, nor did long-term functional neurological outcomes as assessed by the modified Rankin Scale. CONCLUSIONS Intraprocedural rerupture during coil embolization for ruptured intracranial aneurysms is associated with an increased risk of symptomatic vasospasm and need for temporary and permanent cerebrospinal fluid diversion for hydrocephalus.

Abstract The cases of 5 patients with cerebral gliosarcomas examined by computed tomography are reported and the correlations among the computed tomographic (CT) findings, the surgical and histological aspects, and the prognosis are discussed. In some patients, these tumors appear on CT scan as intracerebral lesions, with large necrotic areas and peripheral contrast enhancement; this CT aspect, similar to that of glioblastomas, corresponds to a diffusely infiltrating growth of the tumor and the prevalence of a gliomatous component. In other patients, the tumor appears on the CT scan as a hyperdense mass with well-defined margins and homogenous contrast enhancement;; this CT finding, which may mimic that of a meningioma, corresponds to a rather well-demarcated surgical aspect and the prevalence of sarcomatous component. In our series, we have also noticed a more prolonged survival in a patient with a CT aspect that suggested a meningioma and prevalence of the sarcomatous component.

Background Computed tomography (CT) is often used to confirm the diagnosis of encapsulating peritoneal sclerosis (EPS) but there is no consensus on specific CT abnormalities. To establish CT findings characteristic for EPS, we compared CT findings between EPS patients and long-term peritoneal dialysis (PD) patients without EPS. Methods We included as cases all EPS patients in our center from 1996 to 2008 that underwent a CT scan at the time of diagnosis. Controls were all other long-term PD patients (PD duration ≥ 4 years) without EPS that had a CT scan for different reasons. The CT scans were blindly and independently reviewed by 3 radiologists: 2 abdominal radiologists with PD knowledge (Observers 1 and 2) and 1 radiologist without PD experience (Observer 3). Results We included 15 EPS patients and 16 controls. Observer 1 found 6 CT findings that were significantly more often present in EPS than in controls ( p ≤ 0.05): peritoneal enhancement, thickening, and calcifications; adhesions of bowel loops; signs of obstruction; and fluid loculation/septation. Observer 2 scored almost identically but Observer 3 scored differently. The sensitivity and specificity of a combination of specific CT findings were, respectively, 100% and 94% for Observers 1 and 2, and 79% and 88% for Observer 3. Conclusion CT scans showed characteristic abnormalities that were significantly more often present in EPS patients compared to long-term PD control patients. CT can be used to confirm the diagnosis of EPS when experienced radiologists apply a combination of specific CT findings.

abstract Craniopharyngioma usually presents on a computed tomographic (CT) scan as a hypodense or isodense lesion, with calcification, in the suprasellar region. A case with atypical CT findings of a huge, homogeneous, high density, apparently solid, lobulated suprasellar mass is presented. An explanation for the appearance of the tumor is discussed based upon clinical analysis of the tumor contents.

AbstractThe purpose of our research is to explore whether vitamin D levels were associated with the rupture of intracranial aneurysms. In this retrospective study, 105 patients diagnosed with ruptured intracranial aneurysms (RIAs) and 185 patients diagnosed with unruptured intracranial aneurysms (UIAs) at The First Affiliated Hospital of Zhengzhou University were recruited from September 2019 to September 2020. Patients’ demographic and clinical information, including vitamin D levels, were recorded and compared. Univariate analysis showed that patients with UIAs had higher vitamin D levels than RIAs (p = 0.019). In addition, there were significant differences in aneurysm location (p < 0.001), aspirin use (p = 0.001), and comorbid diabetes mellitus (p = 0.037) between patients with UIAs and RIAs. Binary logistic regression analysis showed that the level of vitamin D was independently associated with RIAs [odds ratio (OR) 0.960; 95% confidence intervals (CI), 0.926–0.996, p = 0.028].
