A case of renal pseudotumor associated with chronic pachymeningitis.
BACKGROUND
A 56-year-old woman was referred to our hospital with a left renal mass.


RESULTS
Radiologic studies demonstrated a solitary space-occupying lesion in the left kidney and a malignant tumor was suspected. Left radical nephrectomy was then performed. Pathological examination revealed a sclerotic fibrous lesion with a rather distinct margin and no evidence of malignancy. These pathological findings were consistent with the diagnosis of a renal pseudotumor.


CONCLUSIONS
This patient had a history of chronic pachymeningitis that formed a thoracic epidural focus causing spinal cord compression and the histologic appearance of this focus was similar to the renal lesion. It was concluded that this was a rare case of a renal pseudotumor associated with multifocal fibrosclerosis.
