An Incidental Solitary Plasmacytoma of Bone Mimicking Neuroendocrine Tumor Metastasis on 68Ga-DOTATATE Positron Emission Tomography/Computed Tomography
A 54-year-old woman with suspicion of neuroendocrine tumor (NET) was referred for 68Ga-DOTATATE positron emission tomography/computed tomography (CT) imaging due to clinical findings. A well-defined osteolytic lesion on the corpus of the third lumbar vertebra was evident on CT images with mild uptake of 68Ga-DOTATATE, which led to suspicion of NET metastasis. Histopathologic examination reveale...
متن کاملPaget’s Disease Mimicking Bone Metastasis in a Patient with Neuroendocrine Tumor on 68Ga-DOTANOC PET/CT
Somatostatin (SST) is a neuropeptide present in neurons, endocrine cells, and a wide range of neuroendocrine tumors (NETs). 68Ga-DOTATOC, 68Ga-DOTANOC, and 68Ga-DOTATATE are current SST analogues used for PET/CT which bind to SST receptors expressed in NETs. These SST analogues have been used successfully for diagnosis of SST-expressing tumors with a more sensitive detection technique than conv...
متن کاملIntra-pancreatic Accessory Spleen Mimicking Pancreatic Neuroendocrine Tumor on 68-Ga-Dotatate PET/CT.
Neuroendocrine tumors (NETs) are rare tumors, but the incidence is increasing with new diagnostics. A 37-year-old man was admitted to our hospital for an incidental 17-mm nodule in the tail of the pancreas. PET/CT shows indeterminate mass in the pancreatic tail with enhanced uptake of 68-Ga-dotatate. NET was suspected and laparoscopic distal pancreatectomy was performed. Pathologic examination ...
متن کاملHepatic adrenal rest tumor mimicking hepatocellular carcinoma
Adrenal rest tumor in liver is a very rare tumor. It originates from an adrenal rest, which is derived from the aberrant adrenocortical tissue. Adrenal rest tumor is an ectopic collection of adrenocortical cells in extra-adrenal sites. This tumor may be hormonally active and manifest endocrine syndromes. But, most tumors are non-functioning and benign. Histologically, hepatic adrenal rest tumor...
متن کامل68Ga-DOTATATE PET/CT Interobserver Agreement for Neuroendocrine Tumor Assessment: Results of a Prospective Study on 50 Patients.
We evaluated observer agreement for 68Ga-DOTATATE PET/CT interpretations in patients with neuroendocrine tumor (NET). METHODS 68Ga-DOTATATE PET/CT was performed on 50 patients with known or suspected NET of the small bowel (n = 19), pancreas (n = 14), lung (n = 4), or other location (n = 13). The images were reviewed by 7 observers, who used a standardized interpretation approach. The observe...
