Fifteen months later, imaging studies demonstrated a 2.3-cm fluorodeoxyglucose ([sup.18]F)-avid splenic nodule
. The patient's serum carbohydrate antigen (CA) 125 level was within normal limits and the serum CA 19-9 level was slightly elevated at 56 U/ mL (reference range: 0-37 U/mL).
(1) Continuous type--the spleen and splenic remnants adhered to the testis/ovary, epididymis, or deferent duct are attached through a cord like structure which may be fibrous, totally splenic or beaded with multiple splenic nodule
which is usually in a retroperitoneal location, but may sometimes be intraperitoneal.
Although histopathologic examination of lymphnode was nonspecific for tuberculosis, acid fast bacilli could be demonstrated in the biopsy of splenic nodule
in this case (9).
In the early stages, eventual fusion of splenic nodules
results into formation of the spleen.
Splenic nodules usually appear as multiple and hypoechoic focal lesions; they show different size on US (usually less than 10 mm but larger lesions may occur) and are hypovascular on Color Doppler US (Figure 3) .
have recently reported a case of incidental finding of multiple hypoechoic and nonvascular splenic nodules that were associated with a significant retraction of the overlying splenic capsule; splenomegaly was not found and no other organ involvement was documented.
MRI can also serve as an adjunctive diagnostic tool to confirm the presence of both hepatic and splenic nodules that appear hypointense, relative to the adjacent parenchyma on all sequences, without substantial contrast enhancement after gadolinium administration, and appear less evident on delayed imaging, suggesting equilibration.
