Abstract
BACKGROUND

This case report demonstrates the simultaneous development of a gastrointestinal stromal tumour (GIST) with arteriovenous malformations (AVMs) within the jejunal mesentery. A 74-year-old male presented to the department of surgery at our institution with a one-month history of abdominal pain. Contrast-enhanced computed tomography revealed an AVM. During exploratory laparotomy, hyperspectral imaging (HSI) and indocyanine green (ICG) fluorescence were used to evaluate the extent of the tumour and determine the resection margins. Intraoperative imaging confirmed AVM, while histopathological evaluation showed an epithelioid, partially spindle cell GIST.

CASE SUMMARY

This is the first case reporting the use of HSI and ICG to image GIST intermingled with an AVM. The resection margins were planned using intraoperative analysis of additional optical data. Image-guided surgery enhances the clinician’s knowledge of tissue composition and facilitates tissue differentiation.

CONCLUSION

Since image-guided surgery is safe, this procedure should increase in popularity among the next generation of surgeons as it is associated with better postoperative outcomes.

Core Tip: Three imaging techniques and histopathology were used to determine the nature of the formation. Computed tomography diagnosed the arteriovenous malformation, but could not rule out any malignancies. Indocyanine green confirmed the initial diagnosis of the vascular malformation and helped with the resection margins. Hyperspecteral imaging on the other hand, suggested the presence of a tumour, which was confirmed later by histological examination. The combination of both intraoperative techniques allowed students and surgical novices to understand the underlying anatomy and the vascular supply of the tumour.
