GP mycosis and EIPH present with which pattern of epistaxis?

• A. Unilateral
• B. Bilateral
• C. Intermittent
• D. No Epistaxis

Answer: (B)

The key idea is that when these bleeding problems show up, the blood tends to exit through both nostrils rather than just one. Guttural pouch mycosis involves erosion of vessels near the guttural pouch, and while a single vessel can be the first to bleed, the disease can affect multiple vessels or cause diffuse mucosal friability on both sides, leading to blood seen from both nostrils. Exercise-induced pulmonary hemorrhage stems from rupture of capillaries in the lungs during intense exercise; the blood tracks into the airways and can emerge through both nasal passages after exertion. So, the pattern you’re most likely to observe with either condition is bilateral epistaxis.
