A 3.5-year-old female Peruvian guinea pig was examined because of a history of anorexia, abdominal pain, and a palpable abdominal mass. Physical examination revealed a round, well-defined mass in the cranial abdomen. When palpated, the abdomen was slightly painful. Ultrasonography revealed a round hyperechogenic mass situated in the gastrointestinal tract, anatomically in the area of the stomach. Abdominal exploratory surgery was performed, and a 4-cm diameter compact trichobezoar was removed from the stomach through a gastrotomy incision. Postsurgical recovery of the guinea pig was uneventful. Four months after surgery, the guinea pig was in good clinical condition. Prophylactic treatment consisted of a changed diet containing a higher percentage of hay; additionally, the hair was kept short by the owner, and an oral lubricant paste was given with the intention to lower the risk of recurrence.
