RESUMEN
Recent studies have shown a significant increase in the utilization of computed tomography (CT) scans in the emergency department for a broad spectrum of conditions. This had a significant impact on the identification of patients with serious pathologies in a timely manner. However, the overutilization of computed tomography scans leads to increased identification of incidental findings. For example, pancreatic lesions are not uncommon findings that can be identified in imaging studies performed for other indications. Here, we report the case of a 55-year-old male with a history of urinary stone disease who presented with right flank pain and dysuria. The urinalysis findings revealed numerous red blood cells and leukocytes. Non-contrast computed tomography scan of the abdomen was performed to detect urinary stones, but no hyperdense stones were noted, suggesting the possibility of spontaneous passage of the stone. However, a lesion in the pancreatic tail was observed. This exhibited fat attenuation with no solid component in the pancreatic tail representing a pancreatic lipoma. No surgical intervention was made considering the benign nature of the incidentally detected tumor. Pancreatic lipoma is a very rare benign mesenchymal tumor of the pancreas. Recognition of the classic radiological feature of pancreatic lipoma is essential to avoid unnecessary investigation and procedures.
RESUMEN
Background Urinary tract infection (UTI) is an infection that affects part of the urinary tract. Ultrasound is a noninvasive test that can demonstrate the size and shape of kidneys, presence of dilatation of the ureters, and the existence of anatomic abnormalities. The aim of the study is to estimate the value of ultrasound in detecting urinary tract anomalies after first attack of UTI. Methods This study was conducted at the Nephrology Clinic, New Children's Hospital, Faculty of Medicine, Cairo University, from August 2012 to March 2013, and included 30 children who presented with first attack of acute febrile UTI. All patients were subjected to urine analysis, urine culture and sensitivity, serum creatinine, complete blood count, and imaging in the form of renal ultrasound, voiding cysto-urethrography, and renal scan. Results All the patients had fever with a mean of 38.96°C ± 0.44°C and the mean duration of illness was 6.23 ± 5.64 days. Nineteen patients (63.3%) had an ultrasound abnormality. The commonest abnormalities were kidney stones (15.8%). Only 2 patients who had abnormal ultrasound had also vesicoureteric reflux on cystourethrography. Sensitivity of ultrasound was 66.7%, specificity was 37.5%, positive predictive value was 21.1%, negative predictive value was 81.8%, and total accuracy was 43.33%. Conclusion We concluded that ultrasound alone was not of much value in diagnosing and putting a plan of first attack of febrile UTI. It is recommended that combined investigations are the best way to confirm diagnosis of urinary tract anomalies.
