RESUMO
MR imaging, with its unique soft-tissue contrast resolution, noninvasiveness, and multiplanar capabilities, has been applied to the assessment of tendon abnormalities of the foot and the ankle.

Injuries of the peroneal tendons including peritendinosis/tenosynovitis, tendinosis, rupture, dislocation are being detected with greater frequency since the advent of MR imaging. This article focuses on the normal as well as pathologic MR features of the peroneal tendons.

A 24-year-old female patient was referred for evaluation of primary amenorrhea. Endocrine studies showed elevated gonadotropins, consistent with gonadal failure. At laparoscopy, a normal nulligravid uterus, normal fallopian tubes, and bilateral streak gonads were observed. Histologic studies showed that the left gonad consisted entirely of fibrous tissue, confirming the presence of streak gonads. Chromosome banding studies of peripheral blood and cultures of tissue from the left gonad demonstrated a 46,X,rcp(X;11)(q22;q13) karyotype. A review of reports of X-autosome reciprocal translocations indicated that abnormal gonadal development is associated with break-points in the mid-region of the long arm of the X chromosome.
