The examination confirmed the presence of the lesion; it defined the place (peritoneum) and the features (neoplastic lesion). Computer tomography (CT) confirmed the ultrasound diagnosis and showed an additional smaller lesion. The cytology exam from the CT biopsy showed to be a follicular lymphoma B.
