Sonographic Features of Palpable Breast and Axillary Lesions in Adult Male Patients: A Pictorial Essay.

The male breast is a non-functional and rudimentary organ, but similarly to the female breast, it can be affected by various diseases. In contrast to female breast cancer, male breast cancer has a low incidence, and there is no established breast cancer screening program for male patients. Therefore, the diagnostic evaluation is usually performed in male patients with symptoms such as palpability or pain in the breasts.

Sonographic findings of total colonic aganglionosis in a neonate with Haddad syndrome: A case report.

Haddad syndrome is a rare congenital disorder characterized by congenital central hypoventilation syndrome and Hirschsprung disease. Total colonic aganglionosis is a rare and long-segment form of Hirschsprung disease, which is primarily diagnosed using contrast enemas. However, the diagnostic performance of contrast enemas is relatively low, making the diagnosis of total colonic aganglionosis challenging.

Objective: The aim of this study was to determine the added value of high-resolution diffusion-weighted imaging (DWI) to T2-weighted imaging (T2WI) for evaluation of extramural tumor invasion (EMTI) in patients with primary rectal cancer.

Methods: Seventy-eight patients who had undergone 3.0-T magnetic resonance imaging including DWI (b = 0, 1000 s/mm2, 2 mm iso-voxel) and subsequent surgery were included.

Clinical applicability of shear wave elastography for the evaluation of medial epicondylitis.

Objectives: To evaluate the ability of shear wave elastography (SWE) in diagnosing medial epicondylitis and to compare the diagnostic performance of SWE with that of grey-scale ultrasound (GSU) and strain elastography (SE).

Methods: GSU, SE, and SWE were performed on 61 elbows of 54 patients from March 2018 to April 2019. An experienced radiologist evaluated the GSU findings (swelling, cortical irregularity, hypoechogenicity, calcification, and tear), colour Doppler findings (hyperaemia), SE findings (strain ratio [SR]), and SWE findings (stiffness and shear wave velocity [SWV]).

Internal auditory canal (IAC) stenosis with hypoplasia of the facial and vestibulocochlear nerves is a rare cause of congenital facial palsy. In this case report, a 3-month-old female infant was referred for a neurological developmental assessment for developmental delay and congenital facial palsy. Upon evaluation of developmental delay, hearing loss was detected.

Incidence and risk factors of subclinical umbilical catheter-related thrombosis in neonates.

Introduction: This study aimed to determine the risk factors for subclinical umbilical catheter-related thrombosis (UCRT) and its association with clinical morbidities.

The aim of this study was to evaluate the diagnostic potential of real-time sonoelastography (RSE) in medial epicondylitis by comparing clinically diagnosed patients and patients without medial elbow pain. From July 2016 to December 2017, gray-scale sonographic findings (swelling, cortical irregularity, hypo-echogenicity, calcification and tear), color Doppler findings (hyperemia) and sonoelastographic findings (elastographic grade on a 3-point visual scale and strain ratio from two regions of interest) for 63 elbows of 56 patients were compared. Twenty-four patients with 29 imaged elbows were clinically diagnosed with medial epicondylitis, and 32 patients with 34 imaged elbows had no medial elbow pain.

Prenatal ultrasonography (US) in a 39 year-old woman revealed massive fetal ascites. A fetal abdomino-amniotic shunting procedure was performed. Subsequently, plain radiographs demonstrated diffuse gaseous distention of the bowel and multiple punctate calcifications in the left upper abdomen.

Clinical description of a neonate carrying the largest reported deletion involving the 10p15.3p13 region.

Chromosome 10p deletion is a rare disorder. This is the largest deletion in chromosome 10p reported to date and the first to be diagnosed in the early neonatal period because of severe clinical manifestations. This rare case might help to understand the genotype-phenotype spectrum in infants with 10p deletion.
