Image-guided fine-needle aspiration of retroperitoneal masses: The role of the cytopathologist.

Mehdi G, Maheshwari V, Afzal S, Ansari HA, Ahmad I - J Cytol (2013)

Bottom Line: The results were analyzed to determine sensitivity, specificity, and diagnostic efficacy of cytopathological diagnosis using image-guided FNA techniques.No major complications were encountered.In areas where advanced tests are not available, the cytotechnologist and cytopathologist have a very important role to play in ensuring accurate diagnoses.

ABSTRACT

Background: Retroperitoneal tumors constitute a difficult diagnostic category as they are not easily accessible. The advent of image-guided fine-needle aspiration (FNA) has resolved this problem significantly.

Aims: We present a short study based on guided aspiration of retroperitoneal tumors, in which we have tried to assess the role of image-guided fine-needle aspiration cytology as a tool for pre-operative diagnosis.

Materials and methods: The study was conducted on patients diagnosed with retroperitoneal masses. FNA was performed under image guidance with the help of ultrasonography and/or computed tomography; smears were prepared and meticulously screened according to a fixed protocol. The results were analyzed to determine sensitivity, specificity, and diagnostic efficacy of cytopathological diagnosis using image-guided FNA techniques.

Results: We assessed 38 patients with retroperitoneal masses. In all cases, adequate cellular material was obtained. No major complications were encountered. Statistical analysis was carried out in 35 cases; sensitivity, specificity, and diagnostic accuracy were 100% in these cases.

Conclusion: FNA under image guidance should be considered a first-line diagnostic approach for retroperitoneal and other abdominal tumors, although caution should be exercised in case selection. In areas where advanced tests are not available, the cytotechnologist and cytopathologist have a very important role to play in ensuring accurate diagnoses.

Mentions: Out of 38 cases of retroperitoneal masses, 14 patients were diagnosed with renal lesions, 9 cases were of adrenal masses, and 8 cases were of pancreatic malignancies. The remaining 7 cases comprised miscellaneous tumors. Adequate material was obtained in all cases [Figure 1].
