Madelungâs disease is sometimes misdiagnosed as sialadenitis, an inflammation of the salivary glands. The inflammation may involve any of the glands that make up the salivary gland system (parotid, submandibular and sublingual glands).
However, use of ultrasonographic imaging should never preclude adequate resuscitation or definitive surgical therapy in a patient who is hemodynamically unstable and in whom ectopic pregnancy is strongly suspected. The goal of bedside ultrasonography is to diagnose an intrauterine pregnancy (IUP). Ectopic pregnancy can be reliably excluded in patients with a demonstrated IUP; heterotopic pregnancy remains very rare in patients who are not taking fertility agents.
