This paper describes a case of segmental testicular infarction (STI), a rarely described human condition resulting from partial ischemia of the testis and often resulting from complex, organic, traumatic or metabolic causes, although an idiopathic etiology has been also considered. Being an important human occurrence, STI has not been reported in non-human primates (NHP) and this work is aimed to characterize a fortuitous case of STI in a 20-year-old male rhesus macaque, demonstrated by clinical findings, ultrasonography and histopathology studies. Clinically, the subject presented a significant scrotal wall thickening and in duration of the right testis palpated at its lower pole, while ultrasonography revealed a hypoechoic irregular mass of poorly defined margins. Upon excising this organ, the histological findings demonstrated a well-defined hemorrhagic nodule measuring 1 cm in diameter consistent with segmental testicular infarction, confirmed by further detailed observations disclosing arteriolar wall thickening and a double lumen, indicating post-infarctrecanalization considered an analogous condition seen in human stroke.
