RESUMO
Patients with obstructed defecation syndrome (ODS) form an important subset of patients with chronic constipation. Evaluation and treatment of these patients has traditionally been difficult. Magnetic resonance defecography (MRD) is a very useful tool for the evaluation of these patients. We evaluated the scans and records of 192 consecutive patients who underwent MRD at our center between January 2011 and January 2012. Abnormal descent, rectoceles, rectorectal intussusceptions, enteroceles, and spastic perineum were observed in a large number of these patients, usually in various combinations. We discuss the technique, its advantages and limitations, and the normal findings and various pathologies.
RESUMO
Congenital hemifacial hyperplasia is a rare developmental disorder of unknown etiology, characterized by a marked unilateral facial asymmetry. It involves the hard (bones and teeth) and soft tissues of the face. We report an interesting case of true hemifacial hyperplasia in a 25-year-old male highlighting the clinical and computed tomography imaging findings.
RESUMO
In this study, we present a case of disseminated cysticercosis involving the brain, orbit, myocardium, muscle, subcutaneous tissues, pancreas, and spleen. Imaging studies are described with emphasis on pancreatic and splenic involvement which is a rare manifestation of a rather common disease and has been radiologically demonstrated only once previously. Although the involvement of the pancreas by parasites leading to pancreatitis has been described previously, in our case there was no clinical or biochemical evidence of pancreatitis due to infection by cysticerci.
