We report a case of very rare adrenal tumor. A 54-year-old patient was classified as affected by bilateral adrenal incidentaloma that surprisingly, on histology resulted solitary fibrous tumors. Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm. Only five cases of localization of SFT in adrenal gland are reported in the literature, while the frequency of retroperitoneum localization is more frequent, about 30 cases. Immunohistochemically, SFT can be positive for CD34 antigen, vimentin, CD99, and bcl-2 and usually negative for cytokeratins, chromogranin A, NSE, neurofilaments, synoptophysin, and S-100. Surgical excision remains the main treatment in fact the recurrence is locoregional and correlated with positive margins due to incomplete excision, while distant metastases are correlated with atypical or malignant features.

Background: Hyperaldosteronism involves complex, multidisciplinary management, including clinical testing, radiological exams, and adrenal venous sampling (AVS). This study assesses AVS outcomes at a large referral center, focusing on cannulation success, lateralization of aldosterone-producing adenomas, and correlation with radiological and surgical findings.

Methods: A retrospective review of 153 patients who underwent AVS from September 2016 to January 2024 was conducted.

Adrenal haemorrhage in pregnancy is rare but can lead to significant maternal and foetal morbidity if unrecognised. We present the case of a 25-year-old woman in her second pregnancy, who was admitted at 34+4 weeks of gestation with severe abdominal pain. Despite initial unremarkable assessments, further imaging revealed a left adrenal haemorrhage, with evidence of prior right adrenal infarction, resulting in primary adrenal insufficiency.
