Imaging Features of Paratesticular Masses.

In this pictorial essay, we review the sonographic and other imaging findings of paratesticular masses in correlation with the pathologic findings. The examples include benign and malignant tumors and also non-neoplastic mass lesions of the paratesticular structures. Diagnostic sonographic findings of these mass lesions as well as correlative findings of other imaging methods are presented.

The Role of Adenomyosis in the Pathogenesis of Preeclampsia.

Introduction: Adenomyosis can cause defective deep placentation. Preeclampsia is known to be associated with abnormal placentation. The aim of this study was to compare the presence of adenomyosis on magnetic resonance imaging in patients with and without history of preeclampsia in order to investigate the possible role of adenomyosis in the pathogenesis of preeclampsia.

Assessment of bladder wall thickness in women with overactive bladder.

Objective: To compare bladder wall thickness (BWT) between female patients with overactive bladder (OAB) and aged-matched healthy controls.

Material And Methods: Thirty-six female patients with OAB and 31 healthy women were enrolled in the present prospective observational study. Qmax and Qave were measured by using uroflowmetry in all of the women in the patient and control groups, and also maximum bladder capacity (MBC), post- void residual urine (PVRU), prevoiding and postvoiding BWT were measured by using transabdominal ultrasound.

The Radiologic Evaluation of Pediatric Acute Abdomen; Results of Tertiary Referral Center.

We retrospectively reviewed the clinical records and imaging findings of 252 children. All patients were evaluated by plain abdominal radiographs (PAX) and ultrasonography (US).

Rectus abdominis muscle endometriosis.

Endometriosis is characterized by an abnormal existence of functional endometrial tissue outside the uterine cavity, typically occuring within the pelvis of women in reproductive age. We report two cases with endometriosis of the abdominal wall; the first one in the rectus abdominis muscle and the second one in the surgical scar of previous caesarean incision along with the rectus abdominis muscle. Pre-operative evaluation included magnetic resonance imaging.

Adnexal torsion with dystrophic calcifications in an adolescent: a chronic entity?

Intermittent pelvic pain caused by ovarian cysts in adolescence may be due to torsion or partial torsion of the ovary. We present a case of 18-year old adolescent with symptomatic left ovarian torsion with calcifications demonstrated by pelvic MRI and ultrasonography prior to surgery. The pathologic investigation demonstrated dystrophic calcifications.

Contribution of kinetic characteristics of axillary lymph nodes to the diagnosis in breast magnetic resonance imaging.

Three-dimensional vascular mapping of the breast by using contrast-enhanced MRI: association of unilateral increased vascularity with ipsilateral breast cancer.

Purpose: We aimed to retrospectively compare three-dimensional vascular maps of both breasts obtained by dynamic magnetic resonance imaging (MRI) and determine the association of one-sided vascular prominence with ipsilateral breast cancer.

Materials And Methods: MRI was performed using gadolinium in 194 cases. Two readers scored vascular density using maximum intensity projections (MIPs).

Hepatic perfusion changes in an experimental model of acute pancreatitis: evaluation by perfusion CT.

Purpose: It is known that acute pancreatitis may cause secondary changes in several organs. Liver is one of these involved organs. In different experimental studies hepatic damages were shown histopathologically in acute pancreatitis but there are a few studies about perfusion disorders that accompany these histopathologic changes.

CT and MRI examinations left behind in the radiology department.

Purpose: To retrospectively document the reported computerized tomography (CT) and magnetic resonance imaging (MRI) examinations that were left behind in our radiology department, to calculate their cost, and to determine possible sources of waste in order to draw attention to this subject.

Materials And Methods: The reported and billed CT and MRI examinations for 2003 that were not taken from the radiology department were documented, and the percentage they represented of all CT and MRI performed that year were determined. The total cost of the examinations, including contrast media, was calculated.

Early renal parenchymal histological changes in an experimental model of vesico-ureteral reflux and the role of apoptosis.

Objectives: To observe early renal parenchymal cellular changes in an experimental model of vesico-ureteral reflux (VUR) and to show whether the apoptotic pathway plays a role in these cellular changes.

Material And Methods: Fourteen New Zealand breed rabbits were used and were divided into two equal groups (control and experimental groups). Urine samples were obtained in a sterile manner and cultured.

Anatomic and hemodynamic evaluation of renal venous flow in varicocele formation using color Doppler sonography with emphasis on renal vein entrapment syndrome.

Objective: To investigate the anatomic and hemodynamic properties of testicular venous drainage and its effects on varicocele formation and reflux using color Doppler ultrasound (US) with emphasis on renal vein entrapment syndrome.

Material And Methods: Upper abdominal and scrotal US examinations of 35 varicocele patients and 35 healthy male subjects were performed in the supine position during rest, during a Valsalva maneuver and in the erect position. The aortomesenteric angle and distance (AMA and AMD, respectively), peak mean velocities (PVs) and diameters of different segments of renal veins, testicular vein diameters and duration of flow inversion were measured.

A case of endometrial stromal sarcoma with curvilinear calcification.

Background: Although many histopathological, clinical, and imaging findings of ESS have been described, intense calcifications have not been reported previously.

Case: A 54-year-old female was admitted with vaginal bleeding and abdominal pain. Gynecologic examination revealed a huge, firm pelvic mass extending up to the epigastrium.

Case of Lemierre's syndrome presenting with thyroid abscess.

Lemierre's syndrome is an uncommon condition characterized by post-anginal septicemia due to anaerobes. Reported here is a case of Lemierre's syndrome presenting with thyroid and liver abscesses. At presentation, the 70-year-old female patient complained of fever, jaundice and neck pain.

Lumbosacral transitional vertebral articulation: evaluation by planar and SPECT bone scintigraphy.

It has been suggested that low back pain (LBP) may arise from lumbosacral transitional vertebral articulation (LSTVA) itself. It is known that bone scintigraphy is a valuable tool for the recognition of pain arising from bone and articular diseases. Therefore we aimed to show planar and SPECT bone scintigraphic findings of LSTVA and compare them with the LBP and X-ray findings.

Utility of 99mTc dextran scintigraphy in diabetic patients with suspected osteomyelitis of the foot.

Purpose: Osteomyelitis of the foot is a frequent complication of diabetes mellitus and its diagnosis is often difficult. The goal of this study was to demonstrate the utility of 99mTc dextran scintigraphy in suspected diabetic foot infections.

Materials And Methods: Twenty-six patients (20 males, 6 females, age range 18-80 years) with diabetes mellitus who had a total of 36 foot ulcers or necrosis were studied.

Bilateral retrosternal dislocation and hypertrophy of medial clavicular heads with compression to brachiocephalic vein.

A 36-year-old woman with effort dyspnea for 2 years, venous congestion of the left arm for 6 months and who did not have a history of a thoracic trauma was hospitalized. Posterior bilateral dislocation of the sternoclavicular joints and compression of the brachiocephalic vein were diagnosed and conformed by computed tomography (CT). The joint could not be reduced because of the old dislocation and destruction of the joint in the operation.
