In cases of fibrous dysplasia of the skull with evidence of optic-nerve compression, relief of retro-orbital pain should be an additional consideration when deciding to proceed with surgical management.

Aim:  To present a series of clinical cases of large odontogenic cysts of the jaw treated with surgical decompression and insertion of a drainage stent. Materials and methods:  Fourteen patients with jaw cysts of odontogenic origin were followed up from time of presentation until there was clinical and radiographic resolution of the cystic lesion. The cysts were all treated with surgical decompression and insertion of a stent. Results:  In all cases, there was radiographic evidence of bony infill and complete resolution of the radiolucent area. In those cysts associated with an unerupted tooth, there was also evidence of spontaneous eruption. None of the patients suffered any serious post‐operative consequences. Conclusions:  Decompression is a viable alternative to more aggressive techniques in the management of large cysts of the jaw. There is minimal post‐operative morbidity, and the technique may reduce the need for general anaesthesia.

Aim of the Study To evaluate the accuracy of MRI for follow up after WEB implantation compared to gold standard DSA. Methods A total of 42 aneurysms treated with WEB were included. Two experienced readers analysed the anonymised postprocedural MRI, with TOF sequences with an without gadolinium, and DSA images independently, using the WEB Occlusion Score (WOS). Results From our data we found corresponding WOS results from MRI compared to DSA in 60.53% of the cases. With DSA as reference MRI revealed false positive results in 23.7%, and false negative results in 15.8% of the cases. Interrater agreement was 90.48%. The MRI sensitivity was 84.2%, the specificity 76.32%. Conclusions From this data WEB follow up with MRI alone bears a high risk of false findings and cannot replace DSA for a precise WOS assessment.Disclosure FW consults and proctors for Microvention.
