A case of necrotizing infection of the heart is presented. A 70-year-old woman presented with vague chest and abdominal pain. CT of the abdomen and pelvis was initially obtained, which demonstrated gas in the myocardium of the left ventricle. Subsequent chest CT, endoscopy, and abdominal surgical exploration did not reveal perforated viscus or diaphragm compromise. At median sternotomy, the inferior wall of the heart was found to be necrotic. Culture of the excised tissue grew E. coli. The patient expired shortly after surgical exploration...

BACKGROUND: Renal cell carcinomas represent 85% of malignant renal tumors. Typically, the tumor remains asymptomatic a long time before the appearance of urologic clinical signs. In some cases, metastasis can precede the manifestations of the primary tumor. Different sites are potential metastatic localizations for renal tumors, including skull metastases who represent a very rare location. CASE DESCRIPTION: We report the case of a 65-year-old man presented after the appearance of a skull mass...

INTRODUCTION: Persistent Müllerian Duct Syndrome (PMDS) is a rare sexual disease. It is characterized by the presence of female reproductive structures such as uterus, cervix, fallopian tubes and upper part of vagina in a normal genotypically and phenotypically male. The diagnosis is usually incidental since the patients will present with normal external genitalia and secondary sexual characteristics. Imaging techniques such as magnetic resonance imaging (MRI), computed tomography (CT) scan, or ultrasound (US) could help in the diagnosis...

PURPOSE: Bowel is often the dose-limiting organ in curative pelvic irradiation because of radiation enteritis when dose exceeds 40 to 45 Gy. To limit radiation enteritis, a silicone tissue-expander prothesis (STEP) connected to a subcutaneous self-sealing valve was prospectively used in children undergoing pelvic or abdominal radiation therapy. This study reports the 15-year long-term outcomes of this prospective series. METHODS AND MATERIALS: Between 1987 and 2008, 29 children from 3 Paris institutions received pelvic radiation therapy after surgical placement of a STEP in the pelvis...

OBJECTIVE S-2 alar iliac (S2AI) screws are commonly used as anchors for lumbosacral fixation. A serious potential complication of screw insertion is major vascular injury due to anterior or caudal screw deviation. To avoid screw deviation, the pelvic inlet view on intraoperative fluoroscopy images is recommended. However, there has been no detailed investigation of optimal fluoroscopic incline with the pelvic inlet view. The purpose of this study was to investigate the safety margins and to optimize fluoroscopic settings to avoid screw deviation with 2 reported insertion techniques using 3D analysis software and CT...

Esophageal hiatal hernia involves abnormal abdominal entry into thoracic cavity. It is classified based on orientation between esophageal junction and diaphragm. Sliding hiatal hernia (Type-I) comprises the most frequent category, emanating from right crus of diaphragm. Type-II esophageal hernia engages both left and right muscular crura. Type-III and IV additionally include the left crus. Age and increased body mass index are key risk factors, and congenital skeletal aberrations trigger pathogenesis through intestinal malrotations...

OBJECTIVE: Quantitative evaluation of different bolus-tracking trigger delays for acquisition of dual-energy (DE) computed tomography (CT) iodine maps as an alternative to CT perfusion. METHODS: Prior to this retrospective analysis of prospectively acquired data, DECT perfusion sequences were dynamically acquired in 22 patients with pancreatic carcinoma using dual-source CT at 80/140kV p with tin filtration. After deformable motion-correction, perfusion maps of blood flow (BF) were calculated from 80kVp image series of DECT, and iodine maps were calculated for each of the 34 DECT acquisitions per patient...

Endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD) has been described as an alternative to surgical procedures [1-5]. The patient was a 64-year-old woman with resectable ampullary carcinoma. She was scheduled to undergo pancreatoduodenectomy for the carcinoma; however, obstructive pancreatitis developed. Abdominal computed tomography (CT) revealed dilation of the main pancreatic duct from the tail side of the tumor. Trans-papillary pancreatic duct drainage was attempted; however, the guidewire could not be inserted over the tumor (Figure 1A)...

INTRODUCTION: The complex arterial system makes pancreatic interventions technically challenging for surgeons, and interventional radiologists. The arterial variants may alter tumor resecability, and cause complications in arterial embolization. International data on pancreatic blood supply are variable; therefore, we aimed to determine the frequency of variants of pancreaticoduodenal arterial arcades. MATERIALS AND METHODS: Arteries of human abdominal organ complexes (50) were injected with resin mixture, and then corroded...

Background Recent studies suggest that pericardial adipose tissue (PAT) is associated with whole body adiposity and insulin resistance. Moreover, the incidence of cardiovascular disease (CVD) differs between men and women. Although CVD is more prevalent in men, women suffering from CVD have a higher mortality compared to men. Differences in PAT may account for some of the observed sex differences in manifestations of CVD. Purpose To assess pericardial adipose tissue (PAT) as a biomarker for cardiometabolic risk and to assess potential sex differences...

BACKGROUND: The Focused Abdominal Sonography for Trauma (FAST) exam has been reported to be unreliable in pelvic fracture patients. Additionally, given the advent of new therapeutic interventions, such as Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), rapid identification of intraabdominal hemorrhage compared to zone III hemorrhage may guide different therapeutic strategies. We hypothesized that FAST is reliable for detecting clinically significant intraabdominal hemorrhage in the face of complex pelvic fractures...

Audit is a clinical instrument of government characterized by a whole process of evaluation inter pares to improve medical behaviors in the clinical practice. Different endocrinopathies are underestimated in the clinical and diagnostics practice but they can be a real problem in patients admitted in the departments of Internal Medicine. The Adrenal Incidentaloma (AI) is an accidental discovery with an incidence equal to 4% in radiologic studies but it's rarely considereted in the internal disorders. In the departments of Internal Medicine are hospitalized each year approximately 1...

Schwannoma is a rare tumor that develops from the Schwann cells in the nerve sheath. A 42 years old woman was found incidentally to have a bulky mass in epigastric region. Abdominal ultrasonography CT and MRI have been of aid to know the position and size of the tumor. A massive capsulated retroperitoneal lesion was identified. It moved forward the hepatoduodenal ligament, inferior vena cava laterally and aorta medially. The mass is exte-riorized and detached from adhesions. There were no complications after the operation and the patient was discharged on the fourth post-operative day...

Renal abscesses are uncommon in otherwise healthy children and adolescents who have no underlying renal structural anomalies. A previously healthy, immunocompetent, 14-year-old male without a history of abdominal trauma or urinary tract infection (UTI) was found to have a renal hematoma that became infected and developed into a renal abscess. He presented with a 2-day history of nausea, vomiting, fever and 1-day history of abdominal pain that radiated to the right flank. Clinical examination, blood work, and initial imaging indicated likely infection; however, findings were normal on urinalysis and urine culture had no growth...
