Question:

MRI findings of pulmonary endometriosis is:
1. Hypointense on T1, hyperintense on T2W images.
2. Focal T2 hyperintense lesions.
3. Hypointense on T2W image due to presence of blood products.
4. Hyperintense on T2W image which increases in size & enhancement during menstruation.
5. Hyperintense lesions on T2W image which decreases in size during menstruation.





Answer:

The correct answer for the question "MRI findings of pulmonary endometriosis is:" is:

4. Hyperintense on T2W image which increases in size & enhancement during menstruation.



Explanation
a. Hypointense on T1, hyperintense on T2W images this is a very non specific finding found in many lesions in the chest, not the appropriate answer.

b. Focal T2 hyperintense lesions - Most of the lesions are hyperintense on T2, this is also a non specific finding found in many chest ailments, not specific for endometriosis.

c. Hypointense on T2W images due to presence of blood products - Since endometriotic deposits are mainly hemorrhagic blood products can be depicted on MR imaging. The trick here is hypointensity in T2 is seen only in chronic bleeds due to formation of hemosiderin; in acute setting like catamenial hemoptysis, the lesions display hyperintense signal on T2 W images.

d.  Hyperintense on T2W images which increases in size & enhancement during  menstruation. [On MRI thoracic lesions are hyperintense on T2-weighted spin-echo images that increases in size at the time of menstruation and shows pronounced uptake of intravenous MRI contrast agent as compared with that in the intermenstrual period].

e. Hyperintense lesions on T2W images which decreases in size during menstruation - This is framed exactly opposite of what happen in endometriosis to confuse the reader, is an     incorrect answer.

Abstract
Thoracic endometriosis is a rare form of extrapelvic endometriosis. These patients typically present with catamenial pneumothorax or hemoptysis. Adequate clinical history coupled with HRCT helps in early diagnosis and appropriate management of thoracic endometriosis.
