Thymic Lymphoma


On CT scans, the thymus is enlarged, symmetrically or asymmetrically; this enlargement often makes it difficult to differentiate the thymus from the enlarged surrounding lymph nodes. At times, differentiating the thymus from a thymoma is difficult, although the clinical picture and the presence of other sites of lymphadenopathy are often helpful in the diagnosis.

Laboratory Test

Anti–acetylcholine receptor antibody The anti–acetylcholine receptor (AChR) antibody (Ab) test is reliable for diagnosing autoimmune myasthenia gravis (MG). It is highly specific (as high as 100%, according to Padua et al).  [ 4 ]  Results are positive in as many as 90% of patients who have generalized MG but in only 50-70% of those who have only ocular MG; thus false negatives are common in cases of purely ocular MG. False-positive anti-AChR Ab test results have been reported in cases of thymoma without MG and in patients with  Lambert-Eaton myasthenic syndrome , small cell lung cancer, or rheumatoid arthritis treated with penicillamine, as well as in 1-3% of the population older than 70 years. Tindall reported AChR Ab results and mean Ab titers in a group of patients with MG (see the Table below).  [ 25 ]  Table.
