Abstract
|
|
|
The incidence of thymolipoma or thymic cyst is very rare among the tumors of thymic origin, which are usually benign or invasive thymoma. Thymic tumor has been found among 10 to 15% of the patients with myasthenia gravis (MG). However the
patients
with
thymolipoma or thymic cyst rarely manifestated as MG. Moreover the case of MG with thbymolipoma and thymic cyst is extremely rare ; Only one case has been reported hitherto.
We hereby report a 41-kyear-old woman presenting as ocular MG with thymolipoma and thymic cyst. She complained diplopia, ptosis and headache, which had begun 3 months prior to admission and have been flucturating thereafter. Ocular MG was
confirmed
by
positive Tensilon and Jolly test. Her chest CT showed an enlarged thymus which turned out to be thymolipoma with thymic cyst on the pathologic examination.
Although rare, thymolipoma and/or thymic cyst should be considered in the differential diagnosis of thymic tumor in MG.
