RESUMO
A 64-year-old woman was biochemically diagnosed with hyperparathyroidism. Technetium-99m sestamibi parathyroid scan demonstrated persistent uptake in the left lower pole of the thyroid. She underwent F-18 FDG PET due to unrelated causes. Incidentally, we found focal FDG accumulation in the lower portion of left thyroid lobe. An ultrasound showed a 2.2-cm nodule containing cystic component in the left lower pole of the thyroid. The intact PTH level in the cystic fluid was much higher than the serum intact PTH level, suggesting an intrathyroidal parathyroid adenoma. Left lobectomy revealed an intrathyroidal parathyroid adenoma in the left thyroid lobe.

Crohn's disease and ulcerative colitis are well known risk factors of intestinal cancer in relation to the extent and duration of disease. Rarely, small bowel cancer can develop after a longstanding inflammation of Crohn's disease with a relatively higher incidence than the general population. Signet ring cell carcinoma is a rare condition among intestinal cancers, and the diagnosis or detection is more difficult if the cancer originates from the small bowel. We report a case of a 30-year old female in whom signet ring cell carcinoma of ileum was diagnosed after a 15-year history of Crohn's disease.
