The quartz overgrowths (1%–7%, mean value 4.5%) occur as syntaxial cements forming incomplete or complete rims around quartz grains with the thickness ranging from 10 to 50 μm.
Symptomatic meniscus defects offer the option for meniscus transplantation with porous cell free biomaterials, when a complete meniscus rim is available.
A well-defined lesion was identified in the substance of the posterior horn of the medial meniscus, isointense to bone marrow on all pulse sequences, and suppression of the signal on PDW fat suppressed images, with a complete hypointense rim (see Figs. 1 and 2).
The earliest post settlement stage of Pocillopora shown by Le Tissier ([ 16], Figure 2a) has a complete circular rim of calcified material on the basal plate with scattered areas of calcification within this circle, while in Porites Goreau and Hayes ([ 34], Figure 4-2) show a portion of the rim of the plate as calcified with scattered areas of calcification on the plate.
One of the two remaining nodules (14 mm), slightly hyperechoic compared with the surrounding tissue, presented a nearly complete stiff rim and a wide central elastic area (i.e. the peripheral part of the lesion was blue, the central part was green) and was classified as score 2.
And there's Todd, who completed a rim-to-rim hike of the Grand Canyon less than three months after donating -- he reconnected with a friend whose wife had been transformed by a transplant and knew he "had to do it".
Abscesses had the highest percentage of complete hypointense rims, whereas metastases and gliomas more often featured hypointense arcs and multiple sclerosis lesions equally showed rims and arcs.
This one arrived in a Margarita glass, complete with salt rim and slice of lime, over a tangerine-orange salsa, with a traditional cocktail sauce on the side.
Although the presence of a ring enhancing lesion co-localizing with a complete T2W hypointense rim, and having a T2W homogenous centre is most likely due to IDD, given the degree of overlap with other pathologic processes, these trends do not obviate the need for brain biopsy in all circumstances.
