CT Features of Recurrent Acute Pancreatitis: Early Phase Versus Late Phase.

Objectives: The aim of this study was to investigate the computed tomography (CT) features of recurrent acute pancreatitis (RAP) in the early phase and late phase.

Methods: Recurrent acute pancreatitis data were obtained over the past 5 years. Recurrent acute pancreatitis patients were divided into 2 groups according to the time from RAP onset to performing CT examination: the early phase (first week) and late phase (after the first week) based on the 2012 revised Atlanta classification (RAC).

Iatrogenic arteriovenous fistula of the iliac artery after lumbar discectomy surgery: a systematic review of the last 18 years.

Patients with iatrogenic iliac arteriovenous fistulas (IAVFs) after lumbar discectomy surgeries (LDSs) from our hospital and the published literature were reviewed in order to better understand this clinical phenomenon. Literature from databases about iatrogenic IAVFs after LDSs were retrieved and a patient from our hospital was reviewed with emphasis placed upon the patient's clinical data. From 31 publications and studies of 44 individuals' data, the study revealed L4-L5 and/or L5-S1 intervertebral space levels were mostly involved (62.

Radiomics model of contrast-enhanced computed tomography for predicting the recurrence of acute pancreatitis.

Objectives: To predict the recurrence of acute pancreatitis (AP) by constructing a radiomics model of contrast-enhanced computed tomography (CECT) at AP first attack.

Methods: We retrospectively enrolled 389 first-attack AP patients (271 in the primary cohort and 118 in the validation cohort) from three tertiary referral centers; 126 and 55 patients endured recurrent attacks in each cohort. Four hundred twelve radiomics features were extracted from arterial and venous phase CECT images, and clinical characteristics were gathered to develop a clinical model.

Congenital absence of the right coronary artery: A case report and literature review.

Rationale: Congenital absence of the right coronary artery (RCA) is a rare congenital malformation of the cardiovascular system which may have fatal consequences.

Patient Concerns: A 63-year-old man with a 5-year history of chest pain after exertion which had aggravated for >1 month was advised for admission and computed tomography angiography (CTA) examination of the coronary artery to screen for coronary artery disease (CAD).

Diagnoses: The coronary artery CTA showed absence of RCA arising form the aortic root after which a selective coronary angiography (SCA) examination was done that confirmed the diagnosis of congenital absence of RCA.

A case report and literature review of barium sulphate aspiration during upper gastrointestinal examination.

Rationale: Even though barium sulphate aspiration during upper gastrointestinal examination is a well-known phenomenon, complication such as long-term lung injury and death may still occur. This may depend upon the concentration, amount, anatomy, or certain predisposing factors.

Patient Concerns: A 47-year-old woman who had a barium swallow to screen for foreign body in esophagus.
