Subject Thyroid associated ophthalmopathy; Dysthyroid orbitopathy; Myasthenia gravis; Exophthalmos; Proptosis; Orbit; Medial rectus; Medial rectus muscle structure; Oculomotor muscles; Microsurgery; Thyroid Orbitopathy and Myasthenia
Presenting Symptom Inability to move the right eye to the left and proptosis of the right eye
History A 74-year-old woman presented with an eight-month history of inability to move the right eye to the left and proptosis of the right eye. Her visual acuity was intact. Improved movement of the right eye medially following intravenous injection of Tensilon indicated that the right medial rectus was afflicted with Myasthenia gravis as well as thyroid eye disease. Right medial rectus function improved as myasthenia improved.
Neuroimaging The enlarged medial rectus muscle in the right medial orbit.
Anatomy Orbit; Medial rectus; Medial rectus muscle structure; Oculomotor muscles
Pathology The biopsy of the muscle taken because of the unusual nature of the presentation showing the disrupted myofibrils and the inflammatory cells in the interstitial tissue, which is consistent with dysthyroid orbitopathy. There are no findings on pathology to indicate Myasthenia gravis.
Disease/Diagnosis Thyroid associated ophthalmopathy; Dysthyroid orbitopathy; Myasthenia gravis
Treatment injection with Tensilon.
