Question:

Tumoral calcinosis has which T1- and T2-weighted findings on MRI?
1. Heterogeneously intense on T1W and hypointense on T2W.
2. Hypointense on T1W and hyperintense on T2W.
3. Hypointense on T1W and heterogeneously hyperintense in T2W.
4. Hyperintense on T1W and heterogeneously hyperintense in T2W.
5. Heterogeneously hyperintense on both T1W and T2W images.





Answer:

The correct answer for the question "Tumoral calcinosis has which T1- and T2-weighted findings on MRI?" is:

3. Hypointense on T1W and heterogeneously hyperintense in T2W.



Explanation
Answer: 3. Hypointense on T1W and heterogeneously hyperintense in T2W.

[These masses are typically hypointense on T1W and heterogeneously hyperintense on T2W images, sometimes with fluid-fluid levels apparent [7]. These reflect the absence of fat, and high water content or inflammation, respectively.]

Abstract
Tumoral calcinosis is uncommon in toddlers, and rare within the subscapular area. Although typically benign, tumoral calcinosis is often incorrectly diagnosed prior to biopsy. We present a case of subscapular tumoral calcinosis in a 16-month old girl and discuss the radiological findings on X-ray, ultrasound, computed tomography and magnetic resonance imaging, including the first description of T1-weighted post contrast imaging, which demonstrate the fibrotic components of tumoral calcinosis.
