Аннотация
BACKGROUND: This case study details a rare orbital metastasis originating from the gastrointestinal tract. A patient presented with proptosis of the right eye precipitated by a slow-growing orbital tumor. A biopsy confirmed a low-grade neuroendocrine tumor. Imaging studies were completed, with magnetic resonance (MR) imaging of the orbits providing the most detailed images of the mass. Fusion software images were created from the MR images and indium In 111 pentetreotide (octreoscan) studies, which confirmed the presence of the neuroendocrine carcinoid tumor.
DISCUSSION: Orbital metastases are a rare condition associated with various symptoms, most commonly proptosis and diplopia. Imaging modalities, such as MR, computed tomography, and nuclear medicine technology, are instrumental in detecting and assessing these masses. Fusion imaging software can provide additional opportunities for facilities without hybrid scanners. The treatment of choice for orbital metastases is octreotide therapy; however, radiation therapy, partial or complete surgical removal of the tumor, and chemotherapy also are used.
CONCLUSION: Traditional imaging techniques and fusion imaging techniques are essential for diagnosing and treating orbital metastases.
