Calcifying fibrous pseudotumours (CFPTs) are paucicellular
collagenous lesions with scattered chronic inflammation and focal calcifications.3 Many previous case studies and literature reviews have suggested that CFPT is a cell-poor, end stage of inflammatory pseudotumor (IPT).4 Although lung involvement is reported to be the most common presentation of IPTs, variants are known to involve almost any type of anatomical location.
We think our non-invasive approach has the potential to open avenues to treat or repair
collagenous tissue without causing tissue damage."
The lesions showed a homogeneous eosinophilic
collagenous matrix background, in which some areas displayed hyalinization [Figure 2]b.
When correlated histologically, hyperintensity on T2W and absent enhancement correspond to hypocellular areas with abundant
collagenous stroma.

collagenous stroma.
Uncomfortable loads in flexion along with the previous translation and the time factor can be a cause of distortion or damage of any spinal
collagenous structures.
A complex pattern of anastomosing empty spaces in the dense
collagenous stroma is also seen.
The lesion was well circumscribed and contained fibroblastic spindle cells in a
collagenous background, and some inflammatory cells were seen.
The histopathological examination revealed vascular formations between osseous and
collagenous structures, angiomatosis, and papillary endothelial hyperplasia conclusive of a capillary hemangioma (Figures 4(a) and 4(b)).
The Sirius Red/Fast Green Collagen Staining kit (Chondrex, Redmond, WA, USA, #9046) was used to assess the amount of
collagenous and noncollagenous protein formation by hGFs that were cultured on control and 3% and 5% Ti[O.sub.2] discs (n = 3).
