Adrenal schwannoma is a rare adrenal incidentaloma. It is a benign tumor arising from the Schwann cells. Differentiating benign from malignant adrenal lesions requires a combination of clinical, biochemical, imaging, and histopathological findings. 68Ga-DOTANOC PET/CT is one of the sensitive imaging modalities to detect adrenal lesions such as pheochromocytoma. Multiple benign and malignant lesions show somatostatin receptor expression causing a high probability of false-positive findings on somatostatin receptor imaging. We present a case of adrenal incidentaloma positive on 68Ga-DOTANOC PET, which revealed a benign adrenal spindle cell tumor on histopathology.

Introduction: Congenital Hyperinsulinism (CHI) has not been previously studied in Ukraine. We therefore aimed to elucidate the genetics, clinical phenotype, histological subtype, treatment and long-term outcomes of Ukrainian patients with CHI.
Methods: Forty-one patients with CHI were recruited to the Ukrainian national registry between the years 2014-2023.

Purpose To evaluate the diagnostic performance of gallium 68 (Ga)-DOTA-NaI3-octreotide (Ga-DOTANOC) and fluorine 18 (F)-fluoro-l-3,4-dihydroxyphenylalanine (F-FDOPA) PET/CT in detecting recurrent or metastatic paragangliomas. Materials and Methods This single-center retrospective study included patients with paragangliomas who underwent both Ga-DOTANOC PET/CT and F-FDOPA PET/CT between August 2021 and December 2023. The diagnostic performance of these two tracers in detecting recurrent or metastatic tumors was compared using several metrics, including sensitivity, negative predictive value, and accuracy.
