Rare case of double seronegative ocular myasthenia gravis and non-functional pituitary macroadenoma

Chronic autoimmune neuromuscular disorder known as Myasthenia Gravis (MG). The relationship of myasthenia gravis with pituitary adenomas is relatively uncommon, despite the fact that it is widely known that people with the condition have a higher prevalence of other autoimmune diseases. Here, we describe the case of a 45-year-old Indian man who had complained of severe cephalgia, associated with ocular pain, dizziness, diplopia, ptosis of the unilateral right eye. Although he has a history of severe headaches that started prior to 3 months, his complaints became more obvious at the end of the day. An MRI of the brain revealed an increased pituitary gland that measured 13.7 × 15.5 x 16. 9 mm. Furthermore, post admission histological examinations supported the diagnosis of a double seronegative ocular myasthenia gravis and non-functional pituitary macroadenoma. Following treatment, it was discovered that Pyridostigmin and Prednisolone considerably reduced his myasthenia symptoms. Finally, it should be noted that pituitary tumours are one potential underlying cause of headache in myasthenic patients.
