Figure 5. Atypical haematoma. A 35-year-old man with right inguinal hernia surgery 25 days before, developed a painful mass in the right inguinal canal. The ultrasound performed, showed an anechoic mass with thick septae, which made difficult to differentiate haematoma and hernia recurrence. In this case, the clinical findings and a CT performed after the administration of oral contrast excluded hernia recurrence. In addition, due to pain persistence, a surgical drainage of the collection was performed and serohematic fluid was extracted.
