Diagnosis of Perianal Hematoma
When it comes to diagnosing a perianal hematoma, a physical examination is the primary method used by doctors. Thankfully, this examination is typically non-invasive as perianal hematomas develop externally around the anus and are easily visible. In most cases, there is no need for a physician to perform an internal examination or resort to a colonoscopy to identify a perianal hematoma.
Understanding the Difference between Perianal Hematoma and External Hemorrhoid
Confusing a perianal hematoma with an external hemorrhoid is not uncommon due to their similar appearance and shared causes and symptoms. However, it is important to note that there are distinct differences between these two conditions.
Hemorrhoids are swollen blood vessels that develop inside the anus. While they can occasionally protrude out of the anus, resembling a perianal hematoma, it is worth mentioning that hemorrhoids have the ability to retract back inside. On the contrary, perianal hematomas exclusively occur externally.
