Endolymphatic sac tumor
Endolymphatic Sac Tumor
Endolymphatic sac tumor (pronunciation: en-doh-lim-fa-tik sak too-mer) is a rare, slow-growing malignant tumor that originates in the endolymphatic sac, part of the inner ear known for regulating the volume and composition of endolymph in the inner ear.
Etymology
The term "Endolymphatic" is derived from the Greek words "endo" meaning within, and "lymphatic" referring to the clear fluid that circulates throughout the lymphatic system. The term "sac" refers to the sac-like structure in the inner ear that stores endolymph, and "tumor" is derived from the Latin word "tumere" meaning to swell, commonly used in medical parlance to denote an abnormal growth.
Symptoms
Symptoms of an endolymphatic sac tumor can include hearing loss, tinnitus (ringing in the ears), vertigo (a sense of spinning), and facial palsy (weakness of the facial muscles).
Diagnosis
Diagnosis of an endolymphatic sac tumor typically involves a combination of medical history, physical examination, audiometry (hearing test), and imaging tests such as MRI and CT scan.
Treatment
Treatment options for endolymphatic sac tumor can include surgery, radiation therapy, and chemotherapy, depending on the size and location of the tumor, as well as the patient's overall health.
Prognosis
The prognosis for individuals with an endolymphatic sac tumor varies and depends on factors such as the size and location of the tumor, the patient's overall health, and the success of treatment.
