%X Glomus tympanicum is a type of glomus tumor that affects the middle ear, located at the auricular branch of the vagus nerve. Glomus tumors, in general, are rare, slow-growing tumors and may not require surgery in some patients. It can be challenging to manage due to its hypervascularity, location, and advanced stage of diagnosis. Although glomus tympanicum commonly presents with pulsatile tinnitus and conductive hearing loss, it presented in our patient with large-volume hemoptysis and epistaxis, requiring urgent diagnostic and therapeutic interventions. We highlight the unique presentation of a 48-year-old female with sudden onset large-volume hemoptysis and epistaxis, leading to the discovery of a hypervascular glomus tympanicum in the right middle ear, identified via MRI. On arrival, her vitals were within normal limits, and a physical examination was pertinent for the obvious ongoing bleeding from her mouth. The examination revealed increased respiratory effort and bilateral crackles. Laboratory values were pertinent for hemoglobin of 11.8 g/dl. Ear examination revealed a large, vascular-appearing mass filling the right ear. An MRI of the face and neck showed an avidly enhancing 3.7 cm x 1.8 cm x 1.2 cm mass within the right middle ear and mastoid cavity, extending into the external auditory canal and through the eustachian tube into the nasopharynx. The mass was inseparable from the lateral border of the internal auditory canal in the petrous canal. Due to concern for glomus tympanicum, the patient underwent urgent embolization and subsequent tumor resection. Considering our patient initially presented large-volume hemoptysis, there was concern for alveolar hemorrhage. However, as she had no increased oxygen requirement, there was suspicion of massive epistaxis mistaken for hemoptysis. Due to large volume epistaxis, she underwent urgent embolization as resection could have been challenging due to increased vascularity. It is important to remember that massive epistaxis may not present with blood in the anterior nares, thereby delaying diagnosis and management. Furthermore, probing such tumors should be avoided as it may lead to life-threatening bleeding.
