A patient who presented with acute abdominal pain secondary to small bowel angioedema is reported. Characteristic imaging features are highlighted with clarifying images. The importance of considering this diagnosis in patients presenting with acute abdominal pain correlated with the appropriate history is discussed.
Chronic myelomonocytic leukemia (CMML) is an uncommon disorder characterized by monocytosis of the peripheral blood, absence of the Philadelphia chromosome, fewer than 20% blasts, and one or more lineages showing dysplastic features. Splenomegaly is frequently seen and may be massive. A 56-year-old man with stable CMML and moderate splenomegaly presented to the emergency department with generalized abdominal pain and abrupt drop in hemoglobin. Abdominal imaging revealed splenic rupture and emergency splenectomy was undertaken, with complete recovery. Atraumatic rupture of the spleen has rarely been reported as a complication of CMML or other myelodysplastic disorders. This report should alert physicians to consider this diagnosis in patients with CMML and acute abdominal pain.
Colicky lower abdominal pain can have several causes. Besides the typical urological reasons, differential diagnosis should include surgical, internal, and gynecological causes. In particular, in cases of ambiguous calcifications on plain abdominal films - as shown in the presented case - a mature teratoma of the ovary should be taken into consideration.
