Ten cases of an unusual form of carcinoma involving the mucosa and underlying tissue of the tongue, hypopharynx, and larynx are described. All ten of the tumors were evaluated by light microscopy; five were also studied by electron microscopy. The major histopathologic feature is carcinoma with a basaloid pattern in intimate association with squamous cell(More)
OBJECTIVE Detection of tears of the anterior cruciate ligament with MR is usually based on the appearance of the ligament. However, other MR findings may be useful to establish the diagnosis. We assessed the utility of these ancillary MR findings for detecting tears and for differentiating partial from complete tears of the anterior cruciate ligament. (More)
OBJECTIVE The fast spin-echo pulse sequence allows T2-weighted MR images to be acquired more rapidly than is possible with conventional spin-echo sequences, and phased-array coils can provide a higher signal-to-noise ratio than is possible with the body coil. The combination of these methods permits higher resolution images to be obtained with more signal(More)
Most previous studies of MR imaging for detection of chondromalacia have used T1-weighted images. We correlated findings on axial MR images of the knee with arthroscopic findings to determine MR findings of chondromalacia patellae on T2-weighted and proton density-weighted images. The study population included 52 patients who had MR examination of the knee(More)

MR imaging has improved the detection and characterization of cysts arising in the ovaries. Although they are less common, cysts also can develop in the endocervical glands (nabothian cysts), labia (Bartholin’s cysts), vaginal wall (Gartner’s cysts), and broad ligament (paratubal cysts). Findings on pelvic MR imaging were reviewed to determine the(More)
The 10 major ligaments and nine major tendons of the ankle were evaluated in 17 ankle MR studies to determine the incidence of visualization of each structure in each of the three orthogonal planes. High-resolution technique was used, with 3 mm slice thickness and an in-plane resolution of 0.6 mm. Of the 19 ligaments and tendons evaluated, 18 demonstrated(More)
Lateral ovarian transposition (LOT) is a useful technique for preserving ovarian function in "high-risk" premenopausal Stage I cervix cancer patients who undergo hysterectomy and subsequent postoperative whole pelvic radiation therapy. From 1978 to 1988, 38 FIGO Stage I cervical cancer patients underwent LOT as part of their initial operative procedure and(More)
We report a case of a patient with uterine leiomyosarcoma. At MRI imaging, the patient was found to have a bilobed uterine mass with two components. While the caudal portion of the mass had the MRI appearance of a simple leiomyoma, the cephalad component showed atypical degeneration with an irregular contour. Malignant degeneration of a leiomyoma was(More)
Magnetic resonance (MR) imaging was performed in 60 patients with ankle pain who were suspected of having various soft-tissue or osseous abnormalities. Results of conventional radiographs had been normal or inconclusive. Soft-tissue disorders depicted by MR imaging included tendon and ligament tears, tendinitis, tenosynovitis, and plantar fasciitis. Osseous(More)
