Contrast echocardiography demonstrating microbubbles in the pericardial space has often been cited as evidence of ventricular rupture requiring emergent surgical intervention. We report a case where no myocardial perforation was found during post-myocardial infarction surgery despite prior echocardiographic evidence of contrast extravasation into the pericardial effusion. Clinical decision making requires balancing imaging evidence with clinical circumstances to determine the optimal timing for surgical intervention.

A 10-year-old neutered male Labrador mix dog presented with a few-day history of stranguria and dysuria. Results of physical examination, laboratory findings, and imaging were consistent with a uroperitoneum and prostatomegaly. Ultrasound showed an enlarged, heterogeneous, and lobular prostate with mineralization, and fluoroscopy showed extravasation of contrast from the prostatic urethra through the prostatic parenchyma into the abdomen.

Objectives: The objective of this study is to evaluate the incidence and volume of contrast medium extrusion when activated with a laser and to compare these outcomes with those of other irrigation techniques.
Materials And Methods: Sixteen cadaver mandibles containing 116 single-rooted teeth were prepared using conventional rotary instrumentation. The teeth were randomly assigned to four irrigation groups: side-vented needle, sonic irrigation, laser activation at the orifice, and laser activation at the middle third of the canal.

Objective: Advanced imaging methods are crucial for understanding stroke mechanisms and discovering effective treatments to reduce bleeding and enhance recovery. In pre-clinical in vivo stroke imaging, MRI, CT and optical imaging are commonly used to evaluate stroke outcomes in rodent models. However, MRI and CT have limited spatial resolution for rodent brains, and optical imaging is hindered by limited imaging depth of penetration.

Rotablator-associated coronary perforation can be fatal if bailout is delayed. Successful bailout is typically defined as the disappearance of contrast extravasation after a haemostatic intervention. We report a case of recurrent cardiac tamponade in the subacute phase, wherein haemostasis appeared to have been achieved on angiography following the implantation of a covered stent during the index procedure.

A 50-year-old patient with a prior history of chronic smoking presented to the emergency department with diffuse abdominal pain, primarily localized to the right hypochondrium and epigastric region, along with nausea, but without fever, vomiting, or urinary symptoms. Laboratory tests were largely unremarkable except for isolated hematuria and a mildly elevated CRP. Given the atypical clinical presentation, a 3-phase abdominal CT scan (without contrast, portal, and delayed phases) was conducted, revealing a horseshoe kidney with an obstructing 4 mm stone at the right ureteral meatus.
