Xanthogranulomatous reaction may develop in macroadenomas, probably triggered by hemorrhagic processes despite no apoplectic episodes. They typically exhibit complex mixed signal intensity on MRI, particularly T1 high- and T2 low-signal intensities, and patients present with pituitary dysfunction.”
“”"Brain surface motion imaging”" (BSMI) is the subtraction of pulse-gated, 3D, heavily T2-weighted image of two different phases of cerebrospinal fluid (CSF) pulsation, which enables the assessment
of the dynamics of Obeticholic cell line brain surface pulsatile motion. The purpose of this study was to evaluate the feasibility of this imaging method for providing presurgical information about adhesions between meningiomas and the brain surface.
Eighteen Cl-amidine mw cases with surgically resected meningioma in whom BSMI was presurgically obtained were studied. BSMI consisted of two sets of pulse-gated, 3D, heavily T2-weighted, fast spin echo scans. Images of the systolic phase and the diastolic phase were obtained, and subtraction was performed with 3D motion correction. We analyzed the presence of band-like texture surrounding the tumor and judged the degree of motion discrepancy as “”total,”" “”partial,”" or “”none.”" The correlation between BSMI and surgical findings
was evaluated. For cases with partial adhesions, agreements in the locations of the adhesions were also evaluated.
On presurgical BSMI, no motion discrepancy was seen in eight cases, partial in six cases, and total in four cases. These presurgical predictions about adhesions and surgical findings agreed in 13 cases (72.2%). The click here locations of adhesions agreed in five of six cases with partial adhesions.
In the current study, BSMI could predict brain and meningioma adhesions correctly in 72.2% of cases, and adhesion location could also be predicted. This imaging method
appears to provide presurgical information about brain/meningioma adhesions.”
“Traumatic pseudoaneurysm of the internal carotid artery (ICA) is a rare but serious complication following blunt or penetrating trauma. These lesions are difficult to repair surgically. Endovascular management, including parent vessel occlusion, bare stent placement, and stent-assisted coil placement, are reported to be safe and effective but have certain disadvantages. Placement of covered stent grafts has been recently reported but without enough follow-up results to achieve consensus.
In this investigation, we present our experience with seven cases of traumatic ICA dissecting pseudoaneurysm treated with stent graft with follow-up between 1 and 33 months.
Among the seven patients, one patient died due to septic shock 7 days after stenting. Follow-up angiography or Doppler ultrasound of the other six patients revealed optimal result with occluded pseudoaneurysm without restenosis of the ICA.
