7-cm, oval-shaped fatty mass with peripheral ring enhancement
projecting anteriorly from the descending colon (Figure 1).
Those with liquid centre are hypointense on T1W1, the centre is hyperintense on T2W1 but the periphery is hypointense and shows ring enhancement
Enhancing cryptococcomas often do not show restricted diffusion on diffusion-weighted imaging (DWI), (9) low signal intensity on T1-weighted imaging, and low (9) or high intensity (12) on T2 imaging, with uniform or ring enhancement.
It was T2 hyperintense, was slightly hypointense on T1-weighted images, and had subtle ring enhancement without perilesional edema.
Differentiating between pyogenic brain abscesses and centrally necrotic intra-axial tumors can often be challenging radiologically, because both commonly demonstrate ring enhancement and perilesional edema.
The lesions may show nodular homogeneous enhancement or ring enhancement, unless the patient has a very low cellular immunity in which case there may be no enhancement (CD4 cell count <50 cells/[mm.
Contrast enhancement is seen in the majority (Figure 2b) although ring enhancement may be minimal and ill defined if the CD4 cell count is low.
MR imaging showed an ovoid well-circumscribed area of low T1 signal intensity with peripheral ring enhancement
and surrounding bone marrow edema (Figures 2 through 3).
Since launching the industry's first dedicated hub, our unique Token Ring enhancement
features have contributed to smooth operations in this environment.
The cost of re-cabling the entire building and disrupting high service levels to 300,000 clients seemed inevitable until LanOptics' unique Token Ring enhancement features came to Laurentian's attention.
We are particularly proud to have been chosen as the Laurentian vendor in three major categories -- Token Ring enhancement that also eliminates recabling costs; comprehensive LAN management with an interface with the Laurentian Life Canadian headquarters management system, and a clear path for network growth and evolution to the high-speed technologies of the future.
Third Ring enhancements
are usually small investments with those intangible signs of personal care and commitment that say, "We're pleased to serve you.
