Abstract

Cerebral venous sinus thrombosis (CVST) on non-contrast CT (NCCT) is often challenging to detect. We retrospectively selected 41 children and 36 adults with confirmed CVST and two age-matched control groups with comparable initial symptoms. We evaluated NCCT placing four small circular ROIs in standardized regions of the cerebral dural venous system. The mean and maximum HU values were considered from each ROI, and the relative percentage variations were calculated (mean % variation and maximum % variation). We compared the highest measured value to the remaining three HU values through an ad-hoc formula based on the assumption that the thrombosed sinus has higher attenuation compared with the healthy sinuses. Percentage variations were employed to reflect how the attenuation of the thrombosed sinus deviates from the unaffected counterparts. The attenuation of the affected sinus was increased in patients with CVST, and consequently both the mean % and maximum % variations were increased. A mean % variation value of 12.97 and a maximum % variation value of 10.14 were found to be useful to distinguish patients with CVST from healthy subjects, with high sensitivity and specificity. Increased densitometric values were present in the site of venous thrombosis. A systematic, blind evaluation of the brain venous system can assist radiologists in identifying patients who need or do not need further imaging.

Abstract

Hemorrhage into a juxtafacet cyst is rare and cyst rupture with hemorrhagic extension into the epidural space is even less commonly seen. We describe the case of a patient with a hemorrhagic synovial cyst with rupture associated to abundant bleeding in the epidural space. A 61-year-old man had a 5-month history of worsening low back pain radiating into the right leg with associated weakness and numbness. A magnetic resonance imaging scan showed the presence of a mild anterior spondylolisthesis of L5 on S1 with increased synovial fluid into both facet joints. A suspected synovial cyst of the right facet joint at level L5-S1, with signal characteristics consistent with hemorrhage was seen. Caudally, epidural blood was evident from S1 to S2 that involved spinal canal and right S1 and S2 foramens. These findings were confirmed at surgery.

Abstract

The aim of the present prospective study was to verify the specificity of non-EPI DWI-MRI in patients operated for middle ear CHO who showed positivity at imaging performed 6 to 9 months after surgery and underwent second-look surgery. All patients underwent 1.5-T non-EPI DWI-MRI 6 to 9 months after surgery: those showing a hyper-intense signal in the middle ear underwent a revision surgery, whilst the others are still under radiological follow-up and were not considered in this study. Two radiologists independently evaluated the images; both placed a standard region of interest inside the brightest part of the observed signal alteration on coronal HASTE-DWI images. The mean and maximum signal intensity values on the DWI images were recorded for each patient. A signal intensity ratio was calculated using the inferior temporal cortex and the background noise. One hundred and forty-three subjects were evaluated for a total of 210 ears. In 116 (170 ears), a normal non-EPI DWI-MRI was found with exclusion from this study, whilst twenty-seven subjects showed a high signal lesion inside the middle ear and underwent revision surgery. According to the ROC analysis, SI, SIRT and SIRTmax showed the best statistical values in comparison with the other parameters. Residual/recurrent CHO can be accurately detected using quantitative evaluation of non-EPI DWI-MRI.
