A 2 year old child is brought to the hospital with a compressible swelling at the root of nose, most likely diagnosis is:: (A) A V malformation, (B) Lacrimal sac cyst, (C) Ethmoid sinus cyst, (D) Meningoencephalocele
Answer is D. Lacrimal sac cyst occurs as a compressible swelling near the medial canthus and not root of nose. Ethmoid cyst (mucocele) presents as a swelling at the medial quadrant of orbit pushing the orbit forwards and laterally. AV malformation is a congenital abnormal connection between aeries and veins, bypassing the capillary system.These are largely found in internal organs and is rare at this site.
