Fine needle aspiration diagnosis of a mesenteric myelolipoma: a case report.
BACKGROUND
Extraadrenal myelolipomas are very rare tumors, with a characteristic, though nonspecific, radiologic appearance. Tissue sampling is necessary for diagnosis, and although most of these tumors are asymptomatic, surgical excision is often indicated.


METHODS
A 59-year-old male was found to have a large mass within the mesentery of the abdomen, incidentally discovered during an ultrasound examination for renal lithiasis. Computed tomography-guided fine needle aspiration biopsy yielded mature adipose tissue admixed with hematopoietic elements.


CONCLUSIONS
FNA proved to be a rapid and effective modality for the diagnosis of this distinctly uncommon tumor.
