Acute Event

Allograft torsion is a rare but potentially devastating outcome of renal transplantation. Patients typically present with an acute onset of abdominal pain, though symptoms are non-specific and can easily be missed in favor of more common diagnoses. Imaging, in particular ultrasound and computed tomography, can aid in the diagnosis of renal transplant torsion by demonstrating characteristic features, and once recognized immediate surgery is typically performed in an attempt to salvage the allograft. However, renal transplant torsion needs not be an acute event; patients can instead present with chronic, waxing, and waning symptoms if the allograft undergoes partial or intermittent torsion. The aforementioned characteristic imaging findings may not be present in this situation. It is essential to recognize partial, intermittent torsion as well, for which imaging can again play a role.

Unclear Etiology

Abstract Para duodenal hernias, the most common type of retroperitoneal hernias, are thought to occur naturally from abnormal gut rotation because of fusion folds within the peritoneum. Retroperitoneal hernias are a rare postoperative complication and have not been described after renal transplantation via a retroperitoneal approach. This case report presents a 48-year-old male with intestinal obstruction after renal transplant due to herniation into the retroperitoneum via an incidentally created peritoneal defect. We suggest computed tomography with oral contrast be used in the early postoperative phase to assess for obstruction in patients with prolonged ileus of unclear etiology who have undergone retroperitoneal dissection. Small peritoneal defects should be closed during dissection. Larger, or multiple peritoneal defects should be extended to make a single, large defect to decrease the possibility of bowel herniating and becoming incarcerated.

AbstractOur understanding of the manifestations of pneumoconioses is evolving in recent years. Associations between novel exposures and diffuse interstitial lung disease have been newly recognized. In advanced asbestosis, two types of fibrosis are seen, probably related to dose of exposure, existence of pleural fibrosis, and the host factor status of the individual. In pneumoconiosis of predominant reticular type, nodular opacities are often seen in the early phase. The nodular pattern is centrilobular, although some in metal lung show perilymphatic distribution, mimicking sarcoidosis. High-resolution computed tomography enables a more comprehensive correlation between the pathologic findings and clinically relevant imaging findings. The clinician must understand the spectrum of characteristic imaging features related to both known dust exposures and to historically recent new dust exposures.

Abstract Background: Bezoar bowel obstruction is a rare entity and remains difficult to detect on imaging studies. Recognition of its characteristic imaging pattern will be useful for diagnosis and management in the setting of intestinal obstruction.Case presentation: We report a 68-year-old female patient who was admitted to the hospital with signs of intestinal obstruction including abdominal pain, nausea, vomiting, and abdominal distention. She was diagnosed with phytobezoar small bowel obstruction on computed tomography (CT) imaging. The patient underwent surgery to confirm the diagnosis and subsequently recovered well.Conclusions: Bezoar is indicated by the sign of floating fat-density debris sign on CT images. It needs to be differentiated from small-bowel feces sign in intestinal obstruction.

Life Threatening Complication

Acute pancreatitis is a rare but life-threatening complication in patients with transplanted kidney. The incidence of acute pancreatitis after kidney transplantation ranges from 2% to 7%, with mortality rate between 50 and 100%. We report a case of a female patient aged 46 years, developing an interstitial acute pancreatitis 8 years following a renal transplantation. The specific aethiological factor was not clearly established, although possibility of biliary pancreatitis with spontaneous stone elimination and/or medication-induced pancreatitis remains the strongest. Every patient after renal transplantation with an acute onset of abdominal pain should be promptly evaluated for presence of pancreatitis with a careful application of the most appropriate diagnostic procedure for each individual patient.

Imaging Properties

Complicated small-bowel diverticulosis is a rather uncommon cause of upper abdominal pain. It may lead to symptoms presenting with an acute onset or to chronic and nonspecific complaints. As the presentation is often similar to other pathologies (acute appendicitis, pancreatitis, or acute cholecystis) and in many cases diagnosis is made on basis of surgical findings, careful analysis of the imaging landmarks may be warranted to aid in the early stages of detection. In this report, we present clinical and morphological findings in three patients where small-bowel diverticulitis was surgically proven. The relevant literature is reviewed, and typical imaging properties are discussed.

Background: Computed tomography (CT) scans’ predictive value is not well established for screening prior to renal transplantation. The purpose of this study is to measure the extent to which CT findings during transplant evaluation alter candidacy.Methods: Data for 639 renal transplant candidates who underwent CT screening were obtained. Of these, 454 patients had sufficient data and met criterium of having undergone screening CT within six months of official renal transplant evaluation. Transplant status before and after CT imaging was assessed.Results: Those who had screening CTs prior to renal transplantation who were older (p=0.01), had coronary artery disease (p=0.006), or had diabetes mellitus (p=0.042) had significant waitlist status changes. Candidates whose CT findings included vascular calcification or pulmonary nodules were more likely to be permanently excluded from the waitlist (p<0.05). Thirty-two, or 7.0%, had a permanent waitlist status change due to pathologic CT findings that precluded transplantation.Conclusions: Focusing on older patients with coronay artery disease, atherosclerosis, or diabetes would reduce the number of CTs obtained during workup. Candidates with systemic vascular calcification or pulmonary nodules found on subsequent imaging are at the greatest risk for permanent exclusion from renal transplantation.

Basilar Skull Fracture

A two-year-old Thoroughbred colt was presented to the Equine Clinic, Onderstepoort Veterinary Academic Hospital for head trauma after rearing and falling backwards, hitting his head on the ground. Following medical therapy for acute onset neurological impairment secondary to a suspected basilar skull fracture, the horse was anaesthetised and computed tomography of the skull was performed. A diagnosis of a comminuted basilar skull fracture was made and skull radiographs were taken for comparison. The horse was subsequently euthanased owing to the poor prognosis; necropsy findings were compatible with imaging findings. The value and limitation of computed tomography versus radiography for the diagnosis of basilar skull fracture are discussed in this report.

Pulmonary edema is a common condition with numerous causes, some of which are infrequently encountered. This review article describes various uncommon conditions/disease that are associated with pulmonary edema and which show characteristic imaging findings on chest computed tomography or other imaging modality. Thus, this review reflects the variety of factors involved in this frequently encountered condition. We demonstrate the wide range of situations that lead to the development of pulmonary edema by showing the imaging findings of unique cases. These rare varieties of pulmonary edema have distinctive imaging and clinical features that aid in providing an accurate diagnosis.

Non-Meckel small intestine diverticulitis can have many manifestations and its management is not well-defined. We report 4 unselect cases of small intestine diverticulitis; all patients were seen by the same physician at the Emergency Center at The University of Texas MD Anderson Cancer Center between 1999 and 2014. The median age at diagnosis of these patients was 82 years (range, 76–87 years). All 4 patients presented with acute onset of abdominal pain, and computed tomography scans showed characteristics of small intestine diverticulitis unrelated to cancer. Most of the diverticula were found in the region of the duodenum and jejuno-ileal segments of the small intestine. The patients, even those with peripancreatic inflammation and localized perforation, were treated conservatively. Non-Meckel diverticulitis can be overlooked in the initial diagnosis because of the location of the diverticulosis, the age of the patient, and the rarity of the disease. Because patients with non-Meckel small intestine diverticulitis can present with acute abdominal pain, non-Meckel small intestine diverticulitis should be considered in the differential diagnosis of patients with acute abdominal pain, and computed tomography scans can help identify the condition. Because of the rarity of non-Meckel small intestine diverticulitis, few studies have been published, and the data are inconclusive about how best to approach these patients. Our experience with these 4 elderly patients indicates that non-Meckel small intestine diverticulitis can be treated conservatively, which avoids the potential morbidity and mortality of a surgical approach.
