Quadriscupid aortic valve with concurrent aortic stenosis and insufficiency

We present the case of a 22-year-old man with a congenital mixed aortic valve dysfunction who underwent cardiac Magnetic Resonance Imaging (MRI) for the assessment of aortic valve morphology and function prior to valve replacement. Cardiac MRI showed a four-leaf-clover aortic valve morphology, the typical presentation of a quadricuspid aortic valve. The patient underwent a successful Bentall procedure to replace the aortic valve, aortic root and ascending aorta. This case report illustrates the MRI findings of a quadricuspid aortic valve with associated aortic stenosis and regurgitation

Stroke versus seizure : perfusion computerized tomography in a patient with aphasia

Both stroke and seizures have varied clinical presentations and their differentiation in the acute setting is not always straightforward. We present the case of a patient who presented at the emergency room with acute onset aphasia. Clinically acute ischemic stroke was suspected. Perfusion CT was performed and demonstrated cortical hypervascularity in the left partietotemporal region. Additional MRI and EEG were performed and a final diagnosis of postictal aphasia was made. This case illustrates that perfusion CT is not only a useful tool for acute stroke management, but can also aid in the detection of seizures in patients presenting with stroke-like symptoms

CT in a Neonate with Nasal Obstruction

A three-day-old girl was referred to the radiology department by the otorhinolaryngologist for work-up of nasal obstruction as she presented with loud nasal respiration and respiratory distress during feeding. Nasal endoscopy revealed a bilateral intranasal mass. CT of the sinonasal region showed a bilateral soft-tissue mass at the medial canthus, with bilateral widening of the nasolacrimal canal, and revealed the presence of a bilateral endonasal mass below the inferior turbinate (Figures 1–3). This triad of imaging findings is diagnostic for a congenital dacryocystocoele. Endonasal wide marsupialisation using a microdebrider was performed, restoring patency of the nasolacrimal apparatus and resolving the symptoms
