Computed tomography diagnosis of truncus arteriosus type IV: a case report

Truncus arteriosus (TA) is an uncommon congenital cardiac anomaly of which type IV is considered a rare variant. Recognition is crucial for proper treatment planning. The prognosis without treatment is poor. Echocardiography alone may not be useful in evaluation. Computed tomography (CT) finding is complicated. We report an 18 months child with ventricular septal defect (VSD), diagnosed on echocardiography, and further review by CT showed VSD with descending thoracic aorta giving rise to the pulmonary arteries suggestive of pseudo truncus (Collet and Edwards Truncus arteriosus Type IV) and right sided aortic arch with mirror image branching. Keywords: echocardiography, Collet and Edwards, computed tomography (CT), truncus arteriosus, ventricular septal defect (VSD

Case report: ‘Photodynamics of Subependymal Giant Cell Astrocytoma with 5-Aminolevulinic acid’

Subependymal Giant Cell Astrocytoma (SEGA) is a common diagnosis in patients with Tuberous Sclerosis. Although surgical treatment is often required, resection may entail a significant risk for cognitive function given the anatomical relation with critical structures such as the fornices and subgenual area. Therefore, target subtotal resections using minimal invasive approaches focused in the higher metabolic areas are valuable options to preserve quality of life while addressing specific problems caused by the tumor, such as hydrocephalus or progressive growth of a specific component of the tumor. In this report, the authors explore the potential role of 5-ALA in the identification of highly metabolic areas during SEGA resection in the context of minimal invasive approaches
