Severe complications following colonoscopy are rare. This is a case report of a 44-year-old woman, who presented to an emergency department (ED) 24 hours following an uncomplicated colonoscopy performed in an out-patient clinic. Acute contrast-enhanced CT (CECT) was performed, showing acute appendicitis, which was later confirmed by a laparoscopy and histology. Weeks prior, the patient had been admitted to the ED with lower abdominal pain. On this occasion, CECT was performed, showing acute inflammation of the sigmoid colon.

Background: Invasive fungal sinusitis (IFS) can present as a mild disease to life-threatening infection. A recent surge in cases was seen due to the coronavirus disease 2019 (COVID-19) pandemic. Many patients require surgical debridement and hence imaging [contrast-enhanced computed tomography (CECT) of the paranasal sinuses (PNS)] to document the extent of the disease.

Purpose: To create a computer-aided prediction (CAP) system to predict Wilms tumor (WT) responsiveness to preoperative chemotherapy (PC) using pre-therapy contrast-enhanced computed tomography (CECT).
Materials And Methods: A single-center database was reviewed for children <18 years diagnosed with WT and received PC between 2001 and 2021. Patients were excluded if pre- and post-PC CECT were not retrievable.

Purpose: Contrast-enhanced CT (CECT) may be performed immediately following microwave liver ablation for assessment of ablative margins. However, practices and protocols vary among institutions. Here, we compare a standardized bolus-tracked biphasic CECT protocol and compare this with a single venous phase fixed delay protocol for ablation zone (AZ) assessment.

Background: Recent advances in gated cardiac contrast-enhanced computed tomography (CECT) with anesthesia support, enhance the imaging performance in congenital heart disease (CHD). 3D reconstruction of the CECT image is a novel modality that could help manage pediatric cardiac patients.
Methods: A retrospective study of children diagnosed with CHD presenting for surgical intervention (n = 139) was carried out at our cardiac surgical center.

Background: Hepatic sarcomatoid carcinoma (HSC) and hepatic sarcoma (HS) are rare malignancies. Without pathology, the differential diagnosis between these two tumors is difficult due to their frequent overlaps in clinical presentations and imaging features. Currently, there are limited analyses about the ultrasound (US), contrast-enhanced ultrasound (CEUS) and contrast-enhanced computer tomography (CECT) characteristics of HSC and HS.
