BACKGROUND Deeply infiltrating endometriosis affecting the retrocervical region and the rectosigmoid generally requires surgical treatment. Clinical examination, transvaginal ultrasonography (TVUS) and pelvic magnetic resonance imaging (MRI) are useful in the preoperative diagnosis of the involvement of these sites. The objective of this study was to(More)
Takayasu arteritis is a form of large vessel vasculitis with a possible autoimmune origin that may cause stenosis of the aorta and its major branches. Six types of Takayasu arteritis are recognized; the type depends on whether the ascending aorta, descending thoracic aorta, abdominal aorta, aortic cervicobrachial branches, or renal arteries are affected.(More)
This study describes the appearance of Brenner tumors on MR imaging and compares quantitative signal intensity measurements of Brenner tumors with that of other ovarian tumors. A search of pathologic and MR records disclosed patients who had MRIs showing Brenner tumors prior to surgical excision. Patients (21) with other surgically proven ovarian masses(More)
Endometriosis is a common multifocal gynecologic disease that manifests during the reproductive years, often causing chronic pelvic pain and infertility. It may occur as invasive peritoneal fibrotic nodules and adhesions or as ovarian cysts with hemorrhagic content. Although findings at physical examination may be suggestive, imaging is necessary for(More)
This study seeks to analyze the association between adenomyosis diagnosed by magnetic resonance imaging (MRI) and endometriosis. This is a prospective study of consecutive patients. One hundred fifty-two patients with histologically confirmed endometriosis. Patients were submitted to MRI, then divided into Group A (with adenomyosis) and Group B (without(More)
OBJECTIVE The purpose of this study is to describe MR imaging features of an unusual type of meniscal cyst arising from tears of the posterior horn of the medial meniscus in 10 patients. MATERIALS AND METHODS Retrospective review of MR examinations of the knee was performed of 10 patients (nine men, one woman; mean age, 39 years) in whom evidence of a(More)
Liver transplantation is currently an accepted first-line treatment for patients with end-stage acute or chronic liver disease, but postoperative complications may limit the long-term success of transplantation. The most common and most clinically significant complications are arterial and venous thrombosis and stenosis, biliary disorders, fluid(More)
OBJECTIVE To evaluate the accuracy of preoperative magnetic resonance imaging (MRI) findings relative to surgical presence of deeply infiltrating endometriosis (DIE). METHODS This prospective study included 92 women with clinical suspicion of DIE. The MR images were compared with laparoscopy and pathology findings. Sensitivity, specificity, positive(More)
PURPOSE To evaluate the visibility of the main portal vein (MPV) and its tributaries in healthy subjects at thin-section three-dimensional (3D) contrast material-enhanced dynamic fat-suppressed magnetic resonance (MR) imaging and to determine whether this technique provides useful information in the evaluation of patients with cirrhosis. MATERIALS AND(More)
OBJECTIVE The purpose of this article is to discuss and illustrate the most relevant and unique MRI features of groove pancreatitis. CONCLUSION Groove pancreatitis in an uncommon type of focal chronic pancreatitis. Its appearance may resemble pancreatic adenocarcinoma. Although distinction between these two entities remains challenging, knowledge of MRI(More)
