Three cases of dermoid cyst will be described with different clinical presentation and location. MRI and CT finding will be reviewed and correlated with pathological finding. The first case is a 7 year- old child, with suspected diagnosis of stroke which MRI shows a midline posterior fossa tumor with fine occipital dermal sinus, better visualized in CT. The second case is 1 year- old enfant with delayed psychomotor development, a dimple with lock of hair and dorsal hemangioma, which MRI shows a dermal sinus at D4 – D5 level which continues with an intra and extramedullary mass. The last case is 2 year- old child postoperated of mielomeningocele at birth that has neurogenic blader and Chiari II with a cyst mass at conus and low spinal cord insertion. Read More

Significant progress in improving outcome for patients with oncohematological diseases are attributed to intensive chemotherapy, bone marrow transplantation, platelet transfusions, development of new imaging techniques, new antimicrobials and others. All these advances increase the survival of these patients which in turn increases the frequent of risk of infections that are substantial cause of morbidity and mortality in these patients. The purpose of this exhibit is to show the spectrum of infections in these patients; describe the imaging finding according to the etiology and associated factors. There are a number of factors that need to be considered in order to interpret abnormalities seen on radiology as the type of hematological disease, stage of the hematological disease, treatment phase, profile of immunodeficiency, treatment for infection received, patient history and clinical signs. For example, according to type of immunosuppression there are different spectrum of infections but leukemia affect all types of immunosuppression that include neutropenia, T cell defect and B cell defect.

The purpose of this exhibit is to review imagings findings of anomalous pulmonary venous return on angiotomography and describe anomalies associated. Magnetic resonance (MR) imaging and computed tomography (CT) are used in diagnostic and follow – up the congenital vein anomalies. CT provides superior spatial resolution and short time but there is exposure to ionizing radiation. However in many hospital there are only the possibility of obtain CT imaging in neonates and infant. The total anomalous pulmonary venous return (TAPVR) is the result of failure of the common pulmonary vein to connect to the left atrium with persistence of the primitive splanchnic connections of the pulmonary veins. There are four categories: supracardiac, cardiac, infracardiac and mixed. The partial anomalous pulmonary venous return (PAPVR) occurs when some but not all segments of the developing lung failed to establish connections with the common pulmonary vein. Read More
