  • Confirmation of Ectopic Pancreatic Tissue: A Novel Use for 18F-Fluciclovine PET. Clinical nuclear medicine Keller, E. J., de Castro, C. M., Ghanouni, P., Shah, J. 2022


    ABSTRACT: This case features a 21-year-old woman with a history of ulcerative colitis who was incidentally found to have a para-jejunal mass when she presented with an ulcerative colitis flare. The mass was further characterized on MR enterography as most likely representing ectopic pancreatic tissue. Given the normal intense pancreatic uptake of 18F-fluciclovine, PET/CT was subsequently used to confirm that the mass represented ectopic pancreatic tissue.

  • Histologically benign metastasizing tenosynovial giant cell tumor mimicking metastatic malignancy: A case report and review of literature. Radiology case reports Chen, E. L., de Castro, C. M., Hendzel, K. D., Iwaz, S., Kim, M. A., Valeshabad, A. K., Shokouh-Amiri, M., Xie, K. L. 2019; 14 (8): 934-940


    Diffuse-type tenosynovial giant cell tumor (D-TGCT), otherwise known as pigmented villonodular synovitis, is a locally aggressive tumor which can show multiple recurrences but is rarely associated with metastasis. A handful of studies have elucidated the imaging features and clinical course in metastatic D-TGCT with malignant transformation on histology. However, only 5 cases of metastatic D-TGCT with benign histological features have been reported in the literature, with the clinical course and prognosis reported in only 1 case. Therefore, relatively little is known about the implications of histologically benign metastasis on the role of imaging, management, and clinical outcomes. We report a case of a 51-year-old female with recurrent D-TGCT localized to the knee that metastasized to the lymph nodes and soft tissue 3 years after above-the-knee amputation and 16 years after initial diagnosis of localized D-TGCT, despite benign histologic features on lymph node excision. This case highlights the necessity of timely MRI imaging to prevent delayed diagnosis, the role of histological findings on treatment response, and clinical outcomes associated with metastasized D-TGCT.
