- DWI-Detected Ischemic Lesions after Endovascular Treatment for Cerebral Aneurysms: An Updated Systematic Review and Meta-analysis
This systematic review and meta-analysis found the incidence of new postprocedural DWI-detected ischemic lesions after endovascular treatment for intracranial aneurysms to be 47.0% (95% CI, 39.6%–55.8%), regardless of the endovascular procedure used. Studies have shown that almost half of these lesions are asymptomatic, and if small (<5 mm), these lesions have been shown to regress without negative effect on clinical outcome.
- Factors Predictive of Treatment Success in CT-Guided Fibrin Occlusion of CSF-Venous Fistulas: A Multicenter Retrospective Cross-Sectional Study
Multi-institutional retrospective evaluation of patients with CSF-to-venous fistulas treated with CT-guided fibrin glue treatment showed that treatment success may be in part driven by whether the spread of fibrin injectate matches the target drainage pathway of the CVF.
- Prospective, Longitudinal Study of Clinical Outcome and Morphometric Posterior Fossa Changes after Craniocervical Decompression for Symptomatic Chiari I Malformation
This prospective, longitudinal study of patients with Chiari I malformation posterior fossa dural opening and duraplasty quantified the change in the posterior fossa and upper cervical spine morphometrics and determined the change in symptomatology between at baseline and up to 5 years postsurgery. The authors found that symptomatic and MR imaging morphometric changes occurred within the first postoperative year.
- Differentiation between Chondrosarcoma and Synovial Chondromatosis of the Temporomandibular Joint Using CT and MR Imaging
As chondrosarcoma and synovial chondromatosis of the temporomandibular joint share overlapping clinical and histopathologic features, CT and MR imaging can be helpful to differentiate between the 2 entities. High-risk imaging features for chondrosarcoma include the following: lesion centered on the mandibular condyle, destruction of the mandibular condyle, no destruction/sclerosis of the articular eminence/glenoid fossa, infiltration into the tendon of the lateral pterygoid muscle, absent or stippled calcification, periosteal reaction, internal enhancement, and size of ≥30.5 mm.
- Update from the 5th Edition of the WHO Classification of Nasal, Paranasal, and Skull Base Tumors: Imaging Overview with Histopathologic and Genetic Correlation
This manuscript reviews the 2022 World Health Organization update on the head and neck tumor classification, emphasizing the importance of molecular data and genetic alterations in sinonasal neoplasms. It includes new entities and changes to the taxonomy and characterization of tumors.
