OBJECTIVE: The purpose of this paper is to describe the CT findings in
patients undergoing transperineal sonographically guided radioactive seed
implantation with and without laparoscopic lymph node dissection for
treatment of carcinoma of the prostate gland. MATERIALS AND METHODS:
Ninety-six CT scans of the pelvis were retrospectively reviewed in patients
who had undergone radioactive seed implantation of the prostate gland. The
CT readings were correlated with the type of procedure each patient had and
the pathologic results of laparoscopic lymph node dissection. RESULTS: Of
73 patients who underwent laparoscopic lymph node dissection, 42 were found
at CT to have low- attenuation masses along lymph node chains. These masses
resembled necrotic nodes. Only one patient who did not undergo laparoscopic
lymph node dissection had similar findings. Fourteen patients had fluid
collections within the pelvis, 13 of whom had undergone laparoscopic lymph
node dissection. Other imaging findings included ectopic seeds (10
patients) and subcutaneous and intrapelvic air (11 patients). All except
two patients had negative pathology reports for the removed lymph nodes.
CONCLUSION: A wide variety of imaging findings may be seen after
radioactive seed implantation and laparoscopic lymph node dissection,
including masses that resemble necrotic lymph nodes. Radiologists should be
aware of these findings in asymptomatic patients.
