Rectus abdominis muscle abscess due to possible infection of spontaneous hematoma: An unusual presentation

Abstract

Rectus abdominis muscle abscess due to infection of spontaneous rectus sheath hematoma is an uncommon clinical condition. There are many predisposing factors known to cause rectus abdominis muscle abscess and rectus sheath hematoma. If an abdominal wall abscess is not diagnosed and treated in time, it can have serious consequences for life. It is rare for rectus muscle abscess to be detected incidentally without risk factors and clinical symptoms. Clinically, abdominal wall abscesses or hematomas can mimic many abdominal diseases. In this case, we preferred to do a biopsy because even the laboratory and imaging findings were not helpful enough in diagnosis. This case of rectus abdominis muscle abscess highlights the need for a high index of suspicion for patients who present without clinical symptoms and do not conform the usual natural history of the abscess, particularly if they have no risk factors for infection.
