Ultrasound evaluation of urachal abscess in a young infant.

The urachus is a tubular structure extending from the dome of the bladder to the umbilicus. Normally, this allantoic and cloacal remnant obliterates into a fibrous band by late fetal development. Urachal abnormalities include a patent urachus, urachal cyst, umbilical urachal sinus, and a vesicourachal diverticulum. These abnormalities are most often asymptomatic and only come to clinical attention when associated with infection. A 2-month-old male infant presented to our tertiary pediatric hospital with several days of intermittent fevers and a focal region of swelling and erythema over the umbilicus. On physical examination, a tender mass was palpated in the umbilical region. Ultrasound revealed a long tubular structure coursing from the dome of the bladder anteriorly and superiorly to the subumbilical region. This tubular structure was fluid filled with internal echoes suggestive of infection with abscess formation. The urachal abscess was drained surgically, at which time a patent urachus was also excised. This case demonstrates the importance of having a thorough understanding of urachal anomalies when evaluating infants presenting with umbilical pathology.

Characteristics of musculoskeletal radiology job postings to guide radiology trainees.

OBJECTIVE: To review current musculoskeletal (MSK) job market postings to define the listed requirements for practice in order to provide insight to guide residents pursuing fellowship training in MSK radiology to best meet the needs of potential future employers. METHODS: Utilizing the ACR (American College of Radiology) Career Center, a review of the ACR job postings began 6/1/2018 focusing on jobs labeled as musculoskeletal (MSK) subspecialty. E-mail notifications from the career center were reviewed, and jobs were tracked prospectively for 1 year. Data was collected regarding the number of positions, the location, the practice type, and required skills both within musculoskeletal radiology and within the remainder of the radiology subspecialties. RESULTS: 456 postings met the inclusion criteria. Approximately 19% were for a dedicated MSK radiologist, 25% sought a combination of MSK and a general skill set, and 56% were specifically for a general radiologist position. Approximately 29% of jobs require some combination of mammography and/or light interventional radiology (IR). DISCUSSION: Our results indicate that majority of job postings for musculoskeletal radiology require a practice that is not specifically limited to MSK, mirroring trends in other radiology subspecialties. Radiology trainees and program directors should be aware of the needs being demanded by the job market to help guide trainees to individualize their training to best meet the needs of their future employment.

Hepatocellular adenoma(s) arising in nodular regenerative hyperplasia in a patient with systemic lupus erythematosus.

Hepatocellular adenoma (HCA) is a rare benign tumor of the liver with low risk of malignant transformation. It is associated with oral contraceptives/anabolic steroid use, metabolic disease, and rarely, vascular abnormalities. We report an interesting case of HCA arising in a background of diffuse hepatic nodular regenerative hyperplasia (NRH) in a 40-year-old female patient with systemic lupus erythematosus (SLE). She presented with sudden-onset refractory ascites, elevated liver enzymes, diffuse hepatic nodularity and mass lesions on imaging concerning for malignancy. Targeted biopsies of the mass lesion were performed with inconclusive diagnoses. The patient ultimately underwent resection of the mass, which was confirmed as HCA, inflammatory type, arising in a background of NRH. It is not uncommon for SLE patients to have liver manifestations such as NRH, but HCA arising in NRH has not been previously reported. Our case reveals an unusual relationship between HCA and hepatic vasculopathy in the clinical context of a systemic inflammatory condition, the mechanism by which is not fully understood.

Successful medical management of emphysematous gastritis with concomitant portal venous air: a case report.

INTRODUCTION: The causes of diffuse abdominal pain following pelvic surgery are numerous. We present a rare case of acute abdominal pain in a woman in the post-partum period. CASE PRESENTATION: A 25-year-old Caucasian woman with neurofibromatosis type 1 presented to our hospital with diffuse abdominal pain immediately after a cesarean section. The patient was acutely ill and toxic with a fever of 38.8 degrees C, a pulse of 120 beats per minute and a distended abdomen with absent bowel sounds. A computed tomography scan showed air in the wall of the stomach and portal venous system. The patient was successfully treated with intravenous antibiotics, bowel rest and total parenteral nutrition. CONCLUSION: It is rare for a case of emphysematous gastritis associated with portal venous air to be treated successfully without surgery. To the best of our knowledge, to date there has been no reported association of emphysematous gastritis with neurofibromatosis.
