A Young Man with a Rare Case of Adrenal Incidentaloma.

Adrenal incidentalomas (AIs) are adrenal masses discovered as incidental finding, often on imaging studies, unrelated to adrenal disorders. Sometimes, they are discovered as part of work-up for adrenal pathology. AIs are mostly nonfunctional (hormonally silent), but can also be functional (hormonally active). The differential diagnosis includes many primary, metastatic, benign and malignant conditions. The current case is a young male, who went to a peripheral health facility with complaints of dysuria and burning micturition. His laboratory and radiological investigations suggested a urinary tract infection with an incidental finding of adrenal mass. After referral, his detailed work-up was done at Endocrine Clinic of Armed Forces Institute of Pathology (AFIP), Rawalpindi, which revealed history of episodic headaches and palpitations with paroxysmal spikes of high blood pressure up to 200/120 mmHg. Adrenalectomy was performed by laparoscopic surgery. Histopathological examination confirmed the diagnosis of pheochromocytoma with PASS score of 5/20. This is one of the rare cases of adrenal incidentaloma, often an autopsy finding. Pheochromocytoma needs to be investigated in all cases of AIs.
