Extramedullary plasmacytomas (EMPs) are localized plasma cell neoplasms that occur within the soft tissues; by definition they cannot occur within bone. They account for 1-2% of all plasma cell growths and have a great predilection for the upper respiratory tract, without specific manifestations. Males are more frequently affected during the fifth and sixth(More)
Cyst of the canal of Nuck is a rare cause of inguinal swelling in woman. We report a case of a cyst of the canal of Nuck in which sonography showed a tubular cystic structure with internal septae localized within the inguinal canal. Magnetic resonance examination demonstrated that the mass was hypointense on T1-weighted and hyperintense on T2-weighted(More)
BACKGROUND Computed tomography (CT) histogram analysis and chemical-shift magnetic resonance imaging (MRI) are currently used modalities for adrenal mass characterization. However, it is not yet clear which modality can be regarded as most sensitive in terms of adrenal mass characterization. PURPOSE To prospectively compare CT histogram analysis and(More)
OBJECTIVE The objective of our study was to prospectively evaluate the effectiveness of computed tomography (CT) histogram analysis method in the differentiation of benign and malignant adrenal masses. MATERIALS AND METHODS Between March 2007 and June 2008, 94 patients (46 males, 48 females, age range: 30-79 years, mean age: 57.7 years) with 113 adrenal(More)
BACKGROUND Thyroid dysgenesis is the most frequent cause of congenital hypothyroidism (CH), and its genetic basis is largely unknown. Hitherto, two mutations in the human thyroid transcription factor 2 (TTF-2) gene have been described in unrelated cases of CH with cleft palate, spiky hair, variable choanal atresia, and complete thyroid agenesis. Here, we(More)
The Ewing's sarcoma family of tumors is an uncommon group of malignant neoplasms that may be located in both skeletal and extraskeletal regions. Extraskeletal Ewing's sarcoma (EES) is quite rare and predominantly involves the soft tissues of the trunk or the extremities. Herein, we report the case of a 19-year-old female patient who complained of left arm(More)
AIM To compare the diagnostic accuracy of pelvic phased-array magnetic resonance imaging (MRI) and endorectal ultrasonography (ERUS) in the preoperative staging of rectal carcinoma. METHODS Thirty-four patients (15 males, 19 females) with ages ranging between 29 and 75 who have biopsy proven rectal tumor underwent both MRI and ERUS examinations before(More)
A 16-year-old male patient complained of right-sided tinnitus and mild deafness of one-month history. He also had a family history of neurofibromatosis type 2 and a history of a prior operation for left vestibular schwannoma a year ago. Otoneurologic examination revealed moderate sensorineural hearing loss. Magnetic resonance imaging demonstrated multiple(More)
Cardiac MR imaging to date has provided detailed information regarding cardiac structure and anatomy. Recent developments in imaging speed have broadened the applications of cardiac MR from the research laboratory to a wide variety of clinical applications involving assessment of both cardiac function and perfusion. In this review, we present methods used(More)
