What condition describes inflammation of the spleen?

The condition that describes inflammation of the spleen is known as spleenitis. The term itself derives from "spleen," which is the organ in question, and the suffix "-itis," which is used in medical terminology to denote inflammation. When the spleen becomes inflamed, it can be due to various causes, including infections, liver disease, and certain blood disorders. This inflammation can lead to symptoms such as pain or discomfort in the left upper abdomen, along with other systemic symptoms depending on the underlying cause.

Other choices refer to inflammation of different organs or structures: pleurisy is the inflammation of the pleura surrounding the lungs; sinusitis is the inflammation of the sinuses; and retinitis is the inflammation of the retina of the eye. Each of these conditions targets specific systems in the body, further clarifying that spleenitis is the correct term for spleen inflammation.
