A Rare Case of Haemoperitoneum Secondary to Spontaneous Splenic Rupture in a Patient with AL Amyloidosis

Haemoperitoneum due to spontaneous splenic rupture is a rare condition. We present a case of AL-type amyloidosis and chronic kidney disease (CKD) who is presented with diffuse abdominal pain. A contrast-enhanced CT scan of the abdomen revealed moderate to large amounts of free fluid in the peritoneum, indicating splenic rupture causing haemoperitoneum. The patient underwent emergency exploratory laparotomy and splenectomy. After the operation, the patient was closely monitored in the ICU and was transferred to the ward on postoperative day 3. He was discharged home on day 6. This case report highlights a rare occurrence of haemoperitoneum secondary to spontaneous splenic rupture in a patient with AL amyloidosis.
