The recent time off from the blog to work on a chapter has had an unexpected inertia, and it's been hard to get back into the daily routine of coming up with interesting things to write about. Upcoming clinical and academic responsibilities will make it even harder to squeeze the 1-2 hours needed for each post and provide the time and attention that a wife and cat require.
If you'd like to continue the work, let me know and the blog can be yours. I found the effort to be very worthwhile during residency and fellowship, and highly recommended it not only as a self-education tool, but as a great resource/peripheral brain.
Thanks for your support and kind comments over the past 3 years.

The uterus is most commonly involved organ. Ultrasound findings include expansion of the endometrial cavity with an intrauterine mass. The mass is usually hyperechoic to normal myometrium; however, homogeneous echogenic thickening of the endometrium can be the only finding.
CT will also depict expansion of the endometrial cavity (see images above) with an internal mass. The mass can be ill-defined or well-defined, but is usually heterogeneous and lower in attenuation compared to the normal myometrium. Areas of higher attenuation and calcifications can also be seen.
On MRI, MMMTs are heterogeneously hyperintense on T2-weighted images and slightly hypointense on T1-weighted images. Scattered areas T1-hyperintensity may be present, and there is heterogeneous and avid enhancement.
It is important to assess for myometrial involvement, metastatic pelvic and retroperitoneal lymphadenopathy, carcinomatosis, and adnexal involvement.
