INTRODUCTION: Diagnosing lymphoma continues to prove challenging in the clinical practice. Composite lymphoma (CL) is defined by the coexistence of different lymphoma subtypes in the same anatomical location. This condition has seldom been witnessed in the gastrointestinal (GI) tract. We weren't able to find previous cases in the literature about small bowel CL with follicular lymphoma (FL) and classical Hodgkin lymphoma (CHL). Surgery is the treatment of choice to obtain accurate histology, to manage and prevent acute complications...

An inflammatory fibroid polyp (IFP) is a solitary rare benign neoplasm of the gastrointestinal tract, frequently located in the gastric antrum. IFPs account for about 0.1% of all gastric polyps. We report a case of a giant gastric inflammatory polyp of 2.5 cm × 7 cm that determines a gastric outlet obstruction called "ball valve syndrome" mimicking a gastrointestinal stromal tumor (GIST) and a gastric lymphoma, with an intestinal obstruction of high origin. Therefore, due to acute presentation we have decided to submit the patient to a subtotal gastrectomy...

Urachal pathologies are rare and can mimic numerous abdominal and pelvic diseases. Differential diagnosis of urachal anomalies can be narrowed down by proper assessment of lesion location, morphology, imaging findings, patient demographics, and clinical history. We report a case of a 60-year-old male, with a history of unintentional weight loss without associated symptoms, who was diagnosed with locally invasive urachal adenocarcinoma. With this article, we pretend to emphasize urachal adenocarcinoma clinical features along with its key imaging findings with radiologic-pathologic correlation...

Medical staffs like radiological technologists, doctors, and nurses are at an increased risk of exposure to radiation while assisting the patient in a position or monitor contrast medium injection during computed tomography (CT). However, methods to protect medical staff from radiation exposure and protocols for using radiological protection equipment have not been standardized and differ among hospitals. In this study, the distribution of scattered X-rays in a CT room was measured by placing electronic personal dosimeters in locations where medical staff stands beside the CT scanner gantry while assisting the patient and the exposure dose was measured...

Urothelial carcinoma of urinary bladder with divergent differentiation into rhabdomyosarcoma (RMS) is an extremely uncommon aggressive phenomenon. We present a case of a 74-year-old male with bladder carcinoma which metastasized to the abdominal wall as epithelioid RMS. To the best knowledge of our literature searches, an oligometastasis of exclusive heterologous component has not been described before. The clinical, radiological, and immunohistochemistry profile of the patient supported the monoclonal nature of the tumor...

Background: The long-term significance of radiological transmural response (TR) as a treatment goal at the first follow-up scan in small bowel Crohn's disease (CD) has been previously shown. We examined the durability of a long-term strategy of treating to a target of radiological TR and the influence of baseline predictors on the maintenance of TR. Methods: Small bowel CD patients between January 1, 2002, and December 31, 2014, were identified with serial computed tomography enterography (CTE)/magnetic resonance enterography (MRE) before and after initiation of therapy or on maintenance therapy...

The effect of the ceiling-mounted radiation shielding on the amount of the scatter radiation was assessed under conditions simulating obese patients for clinically relevant exposure parameters. Measurements were performed in different projections and with different positions of the ceiling-mounted shielding: without shielding; shielding closest to the patient; and shielding closest to the physician performing the procedure. The protection provided by the shielding was assessed for cardiology when the femoral access is used and for radiology when the physician performs the procedure in the abdominal area...

Acute appendicitis in peritoneal dialysis patients generally presents as abdominal pain and cloudy dialysate. We report a case of acute appendicitis in a peritoneal dialysis patient that presented as poor dialysate fluid drainage and an abnormal abdominal X-ray showing breakage in the continuity of the catheter. Catheter dysfunction in this case was caused by acute appendicitis leading to the formation of adhesions with peritoneal dialysis catheter trapped in it. This resulted in radiological appearance of catheter breakage, although catheter itself was intact...

Multiple intrahepatic arterio-portal fistulas are rare. The majority are isolated and occur secondary to liver trauma including iatrogenic interventions such as liver biopsy. Post-liver transplantation 18 cases have been reported, all secondary to an interventional radiological procedure. We report multiple bi-lobar arterio-portal fistulas in a liver transplant recipient recognized 1 year after transplantation. The donor died due to intracerebral bleeding following blunt head and abdominal trauma. In the present case, the etiology is not very clear...

Ventriculoperitoneal shunt (VPS) insertion is a common neurosurgical procedure for hydrocephalus. Unfortunately, VPS malfunction is not uncommon, with an estimated cumulative rate of 32% at 5 years. As flow through the shunt is influenced by the pressure gradient between the ventricles and the peritoneal cavity, malfunction may be caused by elevated intra-abdominal pressure. We present a rare patient with ascites following ovarian hyperstimulation syndrome (OHSS) leading to shunt malfunction. OHSS is a potentially life-threatening complication of controlled ovarian stimulation caused by the administration of exogenous gonadotropins...

Reports of foreign body in the bladder are rare. Various objects have been retrieved. Diagnosis is mainly by history of lower urinary tract symptoms and low abdominal pain combined with relevant radiological investigations. Treatment depends on the size, nature, and configuration of the object. The approach may be endoscopic or through open surgery depending on the above highlighted factors.
