Injuries related to animal/structure interaction can be found in Free-Stall confinement systems. The dewlap hematoma may be related to an injury caused by contact suffered by the animal with the restraint structure of the Free-Stall's liyng when it lies down to rest. The objective of the present report is to describe a method of diagnosis and treatment used in a dairy cattle that presented an increase in volume located in the region of the dewlap. A primiparous female ½ HZ cow, with approximately 60 days in milk (DIM), accommodated in a Free-Stall confinement system and coming from a farm located in the municipality of Lavras - MG, presented an increase in volume in the dewlap region, without any further clinical manifestation. During the physical exam, the presence of fluid was identified in the swollen region of the dewlap, close to the chest region. Ultrasound examination was performed and the presence of pus was ruled out. Thus, an ultrasound-guided puncture was performed at the site and the presence of blood was confirmed. With these results, the diagnosis of hematoma was confirmed and the etiology was determined: contact injury of the animal with the restraint structure of the lying. The treatment was carried out and there was a significant recovery of the animal. The ultrasound-guided puncture provided the verification of the liquid composition and proved the utility of the ultrasound examination, which was extremely important for this report.
