Central serous chorioretinopathy as a presenting symptom of endogenous Cushing syndrome: a case report

Purpose. To report a case of Cushing syndrome due to adrenocortical adenoma revealed by central serous chorioretinopathy. Methods. A 45-year-old man presented with blurred vision and metamorphopsia in the left eye. He reported few episodes of high blood pressure in the last 3 months. Results. Visual acuity was 20/40 in the left eye. Fundus oculi examination revealed central serous chorioretinopathy in the left eye. Grade 1 hypertension was found. Increased serum and urinary levels of cortisol and reduced serum levels of ACTH were observed. Diagnosis of Cushing syndrome was made. Computed tomography scan revealed a right adrenal mass that was surgically removed; histologic examination showed an adrenocortical adenoma. Three months after surgical treatment, visual acuity improved to 20/20 and central serous chorioretinopathy completely resolved. Conclusions. Central serous chorioretinopathy may be the presenting symptom of Cushing syndrome in a patient with adrenocortical adenoma.
