RESUMO
The rapidly evolving clinical utility of prostate-specific membrane antigen (PSMA) PET/CT as an imaging modality for prostate cancer (PCa) has brought to the forefront a multitude of non-prostatic diseases also exhibiting PSMA radioligand uptake. We report a case of a 71-year-old male with PCa who underwent PSMA PET/CT for recurrence evaluation. The scan demonstrated [68 Ga]Ga-PSMA-11 uptake in the distal ileum. Retrospective enquiry revealed that the patient was a known case of Crohn's disease. This case highlights an uncommon finding of PSMA radioligand uptake in the distal small bowel (non-prostatic benign pathological uptake) in a patient with known Crohn's disease, which may be misinterpreted in the evaluation of PCa.
RESUMO
Fanconi anemia (FA) is a genetic disease associated with the risk of different congenital malformations, bone marrow failure, and predisposition to cancer. Congenital abnormalities of the kidney and urinary tract are not infrequent in FA with renal ectopia being one of them. The incidence of the bilateral pelvic ectopic kidney is restricted to only a few reported cases; however, its association with FA has never been reported in the literature. We present a case of Fanconi anemia in a young girl with apparently fused kidneys on a 99mTc-DMSA planar scan which was confirmed to be bilateral pelvic kidneys on hybrid cross-sectional imaging.
RESUMO
Thyroid carcinoma has an excellent long-term outcome for locoregional disease if adequately treated, but the outcome declines sharply if distant metastatic disease is present. Axillary lymph nodal metastases are unusual in thyroid carcinoma and have a poorer outcome, as they are usually associated with aggressive histopathologies, extensive locoregional disease, and distant metastatic disease. We report 2 cases of thyroid carcinoma with axillary lymph nodal metastases and their management, and we review the literature on such cases.
