Assessment of carotid body tumor and its association with tetralogy of fallot: Effect of the chronic hypoxia

This is a rare combined presentation of Tetralogy of Fallot and carotid body tumor [CBT]. Hypotheses and further discussion provides data for the development of CBT as a response to chronic hypoxemia. This present study demonstrates and discusses such an occurrence

Bilateral Optic Disc Drusen Mimicking Papilledema

BACKGROUND: Optic disc drusen, which are calcified deposits that form anterior to the lamina cribrosa in the optic nerve, may mimic papilledema. CASE REPORT: We report herein three cases referred to us with suspicion of disc swelling and papilledema. Following ophthalmologic evaluation with B-scan ultrasound, red-free fundus photography, and computed tomography, the diagnosis of papilledema was excluded in all cases and optic disc drusen was diagnosed. CONCLUSIONS: Clinical suspicion of optic disc drusen in cases presenting with swelling of the optic nerve head is important in order to avoid unnecessary interventions and anxiety. The reported cases highlight the commonly encountered clinical presentations and the practical aspects of diagnosis and management of optic disc drusen.
