AIM To elucidate the clinical, magnetic resonance imaging(MRI), pathological features of these lesions and asses the incremental value of diffusion-weighted imaging(DWI) in diagnosing *** Fifteen consecutive patients(11 females and 4 males; mean age 40.93 years; age range 13-63 years) with cavernous sinus hemangiomas(CSH) who underwent examination between November 2008 and May 2016 were included for the analysis. MRI, clinical and surgical findings of each patient was retrospectively reviewed. DWI were also analysed and mean-apparent diffusion coefficient(ADC) value was calculated. Eleven patients underwent surgical removal of the lesion and 2 patients had biopsy only. Diagnosis of CSH was confirmed histologically in 13 *** Eleven patients(73%) presented with headaches and 10(66%) had cranial nerve involvement. Extra cavernous sinus extension was noted in 14(94%). Surgery was performed in 13(87%) and post-operative radiation was given to 4(28%) patients. Thirteen patients remained asymptomatic on follow up. Three conspicuous imaging features were highly suggestive of the diagnosis: Lack of diffusion restriction(100%), homogeneous hyperintensity on T2 weighted image sequences(93.3%) and intense post-contrast enhancement(100%). The mean ADC was 1.82 × 10-3 ± 0.2186 cm2/*** T1-weighted hypointensity with homogeneous hyperintensity on T2-weighted sequences, intense enhancement and absence of hemosiderin within the lesion on GRE sequence favour the diagnosis. Facilitated diffusion on DWI differentiates CSH from other solid cavernous sinus lesions and significantly improves the diagnostic accuracy, a critical factor for planning surgery.

Modern fault-resilient microgrids(MGs)require the operation of healthy phases during unbalanced short-circuits to improve the system *** study proposes a differential power based selective phase tripping scheme for MGs consisting of synchronous and inverter-interfaced distributed generators(DGs).First,the differential power is computed using the line-end superimposed voltage and current ***,to make the scheme threshold-free,a power coefficient index is derived and used for identifying faulted phases in an *** protection scheme is tested on a standard MG operating in either grid-connected or islanding mode,which is simulated using PSCAD/*** efficacy of the scheme is also assessed on the OPAL-RT manufactured real-time digital simulation(RTDS)***,the performance of the proposed protection scheme is compared with a few existing *** results show that the selective tripping of faulted phases in MGs can be achieved quickly and securely using the proposed scheme.
