Article Abstract
A 77-year-old woman presented to our hospital with a 2-week history of fever, headache, and induration along the bilateral superficial temporal arteries (STAs). The color Doppler ultrasonography of the STA showed a hypoechoic mural thickening surrounding a residual color flow. A contrast-enhanced photon-counting detector (PCD) CT demonstrated mural thickening and stenosis of the bilateral STAs. The patient underwent a biopsy of the right STA. Histopathological findings were consistent with giant cell arteritis (GCA). The patient's symptoms were temporarily relieved after initiation of steroid treatment, but jaw claudication occurred 2 months later. Contrast-enhanced CT showed improved vascular abnormalities of the STAs but new mural thickening and stenosis of the bilateral maxillary artery. Due to its higher resolution, image contrast, and lower noise, PCD-CT may have great potential in detecting, diagnosing, and monitoring GCA.

Mid-field (0.55-T) MRI may offer an alternative to higher field strengths for pancreatic intraductal papillary mucinous neoplasms (IPMNs) surveillance given high-quality MRCP sequences enabled by longer T2 relaxation times and greater patient comfort resulting from a larger bore and reduced acoustic noise. However, SNR is lower at 0.

Purpose: Creeping fat (CF) in Crohn's disease (CD) is characterized by hyperplastic mesenteric adipose tissue (MAT) encasing fibrotic intestinal segments, marked by significant extracellular matrix (ECM) remodeling and fibrosis. Pericytes have multipotent differentiation potential, can adopt a fibrotic phenotype, and contribute to pathological ECM deposition. However, the cellular mechanisms underlying CF fibrosis remain unclear.

Cytomegalovirus (CMV) is a herpes virus that usually affects immunocompromised hosts. However, there has been a recent increase in CMV-associated infections in immunocompetent hosts, with the most common sites including the gastrointestinal tract, lungs, liver, and spleen. We present a case of a 60-year-old male patient who presented with abdominal pain and diarrhea with radiological findings including circumferential mural thickening in the rectum, rectosigmoid, and descending colon with loss of haustrations in the transverse colon suggestive of colitis with toxic megacolon.

Seed-induced colonic perforation is exceptionally rare but may mimic malignancy or complicated diverticulitis, leading to diagnostic challenges. We report the case of a middle-aged man who presented with acute right lower quadrant abdominal pain. Contrast-enhanced computed tomography (CT) revealed mural thickening and a target-like lesion at the ileocecal junction, raising suspicion for intussusception or carcinoma.

: IPMNs are a possible cause of acute pancreatitis (AP). IPMN-associated-AP is considered a relative indication for surgery for the prevention of recurrent attacks of pancreatitis and for a hypothesized increased cancer risk. The literature is based on surgical series, and no data on the clinical features of AP associated with IPMNs and on the risk of recurrent pancreatitis and pancreatic cancer are available.
