Abnormal uterine bleeding is one of the most common reasons of which patients seek for medical attention. This article reviews the patterns and causes of abnormal uterine bleeding. Laboratory and radiologic studies for evaluation of abnormal uterine bleeding are mentioned. Medical therapy and surgical options are also discussed.

Sarcoidosis is a systemic disorder of unknown etiology with a wide variety of clinical and radiologic manifestations, most commonly pulmonary. We describe two patients with biopsy-proven sarcoidosis and an initial presentation of syncope. We present the results of multimodality imaging evaluation of these patients, with an emphasis on the spectrum of findings provided by cardiovascular magnetic...

Two cases of Madelung disease (benign symmetrical lipomatosis) are presented. The MR findings in this striking condition are demonstrated. Short-repetition-time/short-echo time sequences nicely show the relationship of the cervical lipomatous accumulations to the airway and major neurovascular structures in the carotid spaces. Fat-suppression techniques add no additional information in the radi...

The increase in the detection of small renal masses (SRMs) and their best knowledge leads to a change in the therapeutic management of these lesions. The use of a less aggressive surgical technique or even an expectant attitude is the current tendency, in order to preserve as much renal function as possible. Imaging techniques are essential in the followup of these lesions. It allows us to know...

STUDY DESIGN A cross-sectional imaging study. PURPOSE The objective was to assess the degree of degeneration and the associated factors through imaging studies of the lesion segment and the adjacent superior and inferior segments of isthmic and degenerative spondylolisthesis. OVERVIEW OF LITERATURE Few articles existed for degeneration and related factors in isthmic and degenerative spondyl...

When characterizing a small renal mass (SRM), the main question to be answered is whether the mass represents a surgical or nonsurgical lesion or, in some cases, if followup studies are a reasonable option. Is this a task for a urologist or a radiologist? It is obvious that in the increasing clinical scenario where this decision has to be made, both specialists ought to work together. This pape...

A 47-year-old woman was presented to the emergency department. The limb of the patient was shortened, and her hip was mildly flexed, adducted, and internally rotated. Initially, the patient was misdiagnosed as posterior hip dislocation. However, after careful history taking and radiologic evaluation, her final diagnosis was developmental dysplasia of hip, which was a sequelae of poliomyelitis.

As experience with endocrine diagnosis, radiologic evaluation, and transsphenoidal microsurgery has accumulated, more effective therapy has become available for patients with pituitary adenomas. The amelioration of the various endocrinopathies and the potential for restoration of vision in patients with visual impairment make this aspect of modern neurosurgery most satisfying, both for the pati...

Accurate diagnosis of primary bone tumors requires evaluation of clinical, radiologic, and pathologic features. Thus, communication among the orthopedic surgeon, the radiologist, and the pathologist is necessary to avoid serious diagnostic errors and subsequent therapeutic mismanagement. The following clinical parameters provide essential diagnostic information and should be part of every diagn...

The solitary pulmonary nodule (SPN) is a common diagnostic problem facing the pulmonologist. The incidence of SPNs is increasing primarily because of the increasing use of multidetector CT scanning for the evaluation of chest disease. This article reviews the radiologic assessment of the SPN, with a focus on thin-section CT, positron emission tomography, and CT-guided transthoracic needle biops...
