Subgaleal hematomas are accumulation of blood between periosteum and galea aponeurosis. A 2-year-old male Chihuahua was presented with a severe head swelling after trauma. Radiography and computed tomography (CT) showed a massive swelling encircling the entire calvarial vault, extending toward the cervical neck and crossing the suture line. It was heterogeneously, mild hyperdense fluid to soft tissue attenuating with contrast enhancement on CT images. On day 4, physical and imaging examination showed resolution of the calvarial swelling. Subgaleal hematoma should be considered as a differential diagnosis when there is a massive soft tissue swelling over the skull on physical and imaging examinations.
