# The role of 18F-FDG PET/CT in diagnosing cardiac infiltration and therapeutic evaluation in extranodal nasal-type NK/T-cell lymphoma: a case report

## TL;DR

This case report highlights the use of 18F-FDG PET/CT in diagnosing and monitoring a rare form of lymphoma that affects the heart.

## Contribution

Demonstrates the utility of 18F-FDG PET/CT in a rare cardiac manifestation of extranodal nasal-type NK/T-cell lymphoma.

## Key findings

- 18F-FDG PET/CT accurately identified cardiac infiltration in a rare lymphoma case.
- The imaging technique provided valuable insights for therapeutic evaluation.
- This case underscores the importance of advanced imaging in managing complex lymphoma presentations.

## Abstract

Extranodal nasal-type NK/T-cell lymphoma is closely associated with Epstein-Barr virus (EBV) infection and primarily involves the nasopharynx. We report a rare case of extranodal nasal-type NK/T-cell lymphoma with widespread lymphomatous infiltration, including cardiac involvement, an exceedingly uncommon manifestation. This case emphasizes the pivotal role of18F-FDG PET/CT in diagnosing and evaluating treatment outcomes in extranodal nasal-type NK/T-cell lymphoma
