Sarcoidosis with Splenic Involvement Diagnosed with Endoscopic Ultrasound-guided Fine-needle Aspiration

Splenic sarcoidosis is often diagnosed by splenectomy or an ultrasound-guided splenic biopsy. However, splenectomy is invasive and costly, and a percutaneous biopsy is sometimes difficult. We herein report a case of splenic sarcoidosis diagnosed with endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). A 71-year-old man was referred to our hospital for abnormal shadows on a chest roentgenogram. Computed tomography showed multiple lesions in the spleen and pulmonary consolidations. Bronchoscopy revealed no definitive diagnosis. We therefore performed EUS-FNA for a splenic lesion that led to the diagnosis. This case suggests that EUS-FNA is useful in confirming the diagnosis of sarcoidosis with suspected splenic lesions.
