To present the epidemiology,
clinical manifestations and differential diagnosis of mammary-type myofibroblastoma, 2.
To show the different locations of mammary-type myofibroblastoma with its multi-modality imaging including radiography,
MR and PET/CT.
See attched slide BACKGROUND Myofibroblastoma was first described by Wargotz et al.
in 1987 as a benign tumor of the breast generally seen in older men.
Mammary-type myofibroblastoma is a rare tumor resembling its mammary counterpart.
It is accepted that this tumor arises from accessory breast tissue typically occurring along the embryonic milk-line from the axilla to the medial groin.
Almost half of cases are located in the pelvis or inguinal region.
About 25% of mammary-type...

See attached slides. IMAGING FINDINGS The exhibit presents the spectrum of features of mammary-type myofibroblastoma on ultrasound,
MR and PET/CT imaging and discusses their differential diagnosis based on early or advanced stages of the lesion.
The exhibit also reviews the different sites of mammary-type myofibroblastoma with the pictorial essay of pelvic,
breast and lower extremity involvement.
An instance of recurrent tumor is also...
