Spontaneous intramuscular
hematoma of the
abdominal wall is a rare condition characterized by acute
abdominal pain. It is often misdiagnosed as a surgical condition. It used to be associated with
risk factors such as coughing,
pregnancy, and
anticoagulant therapy. Most cases of
abdominal wall hematomas were rectus sheath
hematomas caused by the
rupture of either the superior or inferior
epigastric artery, but spontaneous internal oblique
hematoma was extremely rare. In this
report, we present a case of spontaneous internal oblique
hematoma in a 69-year-old man with non-
dialysis chronic kidney disease who was taking
cilostazol. The
patient complained of abrupt
abdominal pain with a painful palpable lateral abdominal mass while sleeping. The abdominal computed
tomography showed an 8 cm-sized mass in the
patient's left
internal oblique muscle. The
administration of
cilostazol was immediately stopped, and the intramuscular
hematoma of the lateral oblique
muscle disappeared with
conservative management.
