The findings on the chest x-ray are suggestive of a slow growing soft tissue tumour, likely related to the intercostal neurovascular bundle. The findings are subtle but present, particularly when compared to the left side.
The MRI findings of an isolated, well circumscribed spherical high signal lesion in the intercostal soft tissues, raises the possibility of a schwannoma.
Closer, magnified T2 imaging reveals a subtle fascicular sign and illustrates the value of magnified inspection of lesions. Moreover, the high signal centre is suggestive of central cystic and fatty degeneration, which is common is schwannomas.
The patient has a strong family history of NF2NF3 / schwannomatosis.
