Imaging features of anorectal proctitis in monkeypox infection.

The monkeypox outbreak of 2022 saw the first community-sustained transmission of the monkeypox virus outside of Africa, and rapidly developed into multi-country spread. A common presenting sign of monkeypox infection during this outbreak has been rectal pain due to proctitis. Proctitis with large hypoattenuated anorectal ulcers on CT scan should invoke consideration for monkeypox infection in young homosexual or bisexual men with associated skin eruptions.

Impact of the COVID-19 pandemic on radiology department emergency ultrasound utilization.

Purpose: To analyze the change in utilization of healthcare resources through a review of ultrasound examinations performed in the emergency department of an urban healthcare system in NYC during the time of peak COVID-19 outbreak.

Methods: This is a retrospective review analyzing ED ultrasound exams performed by the radiology department of an urban healthcare system during the 8-week time period of the peak COVID-19 outbreak in NYC, compared to a time-matched period one year prior. Data regarding the examination type and indication were obtained in addition to patient demographics and indicators of outcomes including admission, length of stay, and mortality.

Colostomy on CT and fluoroscopy: What the radiologist needs to know.

Colostomies are commonly created in conjunction with colorectal surgery performed for both malignant and benign indications. Familiarity with the different types of colostomies and their normal imaging appearance will improve radiologic detection and characterization of colostomy complications. The radiologist plays a large role in assessment of colostomy patients either via fluoroscopic technique or multidetector computed tomography (CT) in order to help identify ostomy complications or to aid the surgeon prior to colostomy reversal.

Laparoscopic sleeve gastrectomy: Everything the radiologist needs to know.

Obesity has become an epidemic in the United States, and bariatric surgery is being increasingly performed for its management. There has been an increased number of laparoscopic sleeve gastrectomies performed for the treatment of morbid obesity due to its efficacy and lower complication rate compared to other bariatric surgical techniques. The authors discuss the surgical technique, review the imaging of normal and complicated sleeve gastrectomy, and highlight radiographic pitfalls.

Consensus Statement of Society of Abdominal Radiology Disease-Focused Panel on Barium Esophagography in Gastroesophageal Reflux Disease.

Objective: The Society of Abdominal Radiology established a panel to prepare a consensus statement on the role of barium esophagography in gastroesophageal reflux disease (GERD), as well as recommended techniques for performing the fluoroscopic examination and the gamut of findings associated with this condition.

Conclusion: Because it is an inexpensive, noninvasive, and widely available study that requires no sedation, barium esophagography may be performed as the initial test for GERD or in conjunction with other tests such as endoscopy.

Outside the inside: a review of soft-tissue abnormalities seen on thoracoabdominal computed tomography.

In this review, we illustrate the computed tomographic features of thoracoabdominal soft-tissue abnormalities, which may be easily overlooked and often can provide important information regarding systemic processes. Examples include necrotizing fasciitis, heterotopic ossification, fat necrosis, benign and malignant neoplasms, endometriosis, and collagen vascular disease as well as systemic and congenital pathology.

Aesthetic surgery of the buttocks: imaging appearance.

Familiarity with the imaging appearance and potential complications of buttocks aesthetic surgery is important for radiologists. In this review, we illustrate the spectrum of imaging features after buttocks implants, liposuction, fat injections and silicone injections. Complications such as fat necrosis, abscess, and silicone migration are also presented.

Etiology of small bowel thickening on computed tomography.

Background: Abdominal pain is often evaluated using imaging, most often with computed tomography (CT). While CT is sensitive and specific for certain diagnoses, small bowel thickening is a nonspecific finding on CT with a broad differential diagnosis including infection, inflammation, ischemia and neoplasm.

Method: A review of medical records of patients who underwent CT scans of the abdomen and pelvis over a one-year period and exhibited small bowel thickening were retrospectively evaluated to determine the final diagnosis.

Findings of cecal volvulus at CT.

Purpose: To assess the diagnostic performance of computed tomographic (CT) and radiographic (as seen on CT topograms) signs of cecal volvulus.

Materials And Methods: In this institutional review board-approved, HIPAA-compliant retrospective study, the CT and CT topogram findings in 11 patients (one man, 10 women; age range, 26-100 years) with surgically confirmed cecal volvulus and 12 control patients were reviewed. The control subjects had suspicious radiographs, had undergone CT within 24 hours of radiography, and had received a clinical diagnosis other than cecal volvulus.

CT findings of sigmoid volvulus.

Objective: The purpose of this study was to evaluate the features of sigmoid volvulus on CT scanograms and cross-sectional images.

Materials And Methods: We retrospectively reviewed 21 cases of sigmoid volvulus in 15 men and six women. Three radiologists evaluated scanograms and cross-sectional images for several classic and two novel imaging signs of volvulus: crossing sigmoid transitions (called the X-marks-the-spot sign) and folding of the sigmoid wall by partial twisting (called the split-wall sign).

Small bowel obstruction due to an impacted endoscopy capsule.

Capsule endoscopy (CE), a recently introduced technology, offers important benefits for evaluation of small bowel pathology as compared to traditional radiologic and endoscopic studies. The most striking complication of this modality is capsule retention, which may obligate invasive retrieval. The radiologist should be aware of the natural course, presentation, diagnostic evaluation, and treatment options for this retained foreign body.

Percutaneous gastrostomy of the excluded gastric segment after Roux-en-Y gastric bypass surgery.

A new technique for percutaneous gastrostomy of a decompressed excluded gastric segment after Roux-en-Y gastric bypass (RYGBP) surgery is described and the results in a single institution are reviewed. Computed tomography guidance was used to place a 21- or 22-gauge needle into the lumen of the stomach and distend it to allow placement of a feeding catheter. Ten women underwent the procedure, and despite only three patients having clear access windows, gastrostomy placement was ultimately successful in all 10 patients.
