An 81-year-old woman was admitted to the Mazandaran Heart Center, Sari, Iran in February, 2018 with a 4-day history of nausea, vomiting, and abdominal pain. She had been taking Warfarin (5 mg orally once a day) and aspirin (80 mg/day) for 8 years after aortic valve replacement without close monitoring and had a history of hematochezia caused by Warfarin toxicity one year ago. Colicky pain, an increase in bowel sounds and periumbilical tenderness without distension was determined by physical examination. The primary laboratory findings revealed anemia (Hb: 9.8 g/dl; normal value: 11.5–13.5 g/dl) and elevated INR (6; therapeutic range: 2–3.5), liver function and biochemistry tests were within normal values. Normal left ventricular systolic function, LVEF of 55–60%, septal hypertrophy, normal functioning prosthetic valve, and dilatation of the ascending aorta were reported by echocardiography.\nDuring an abdominal and pelvic ultrasound, long mucosal thickening possibly through the ascending and sigmoid colon was observed, suggestive of intramural hematoma. The patient was placed on\nnil per os, received supportive care and two units of fresh frozen plasma. Due to normal cardiac evaluation and partial relief of symptoms on the second day of admission, the patient was referred to surgical consultation with the possible diagnosis of descending colon and sigmoid intramural hematoma. For re-administration of anticoagulants, heparin infusion (1000 units/hour) began with precise monitoring of prothrombin time.\nOn the fourth day, CT scan was performed with intravenous and oral contrast (\n) and intramural hematoma of ileum was diagnosed. During the CT, a radiologist noticed a mass on the left breast and a lymph node with a malignant feature on the left axilla. With the improvement of abdominal pain and vomiting (on the fourth day), oral feeding was resumed. After mammography and breast biopsy, pathological examination revealed invasive ductal cell carcinoma with lymphatic and perineural invasion. According to the immunohistochemistry staining, tumor cells were strongly ER positive, PR negative, 15% Ki67 positive and equivocal for HER2. The patient was referred to the oncology-hematology department to receive appropriate treatment.\nThe patient was discharged 10 days after admission and Warfarin therapy (5 mg/d) was resumed. The patient was visited 2 weeks later with good general health assessment. Letrozole (2.5 mg/day) was started because the patient refused chemotherapy and radiotherapy.
An 85-year old lady presented as an emergency with sudden onset of severe left sided abdominal pain and vomiting for two days. This was associated with constipation for 3 days. She had a past medical history of atrial fibrillation, angina, and pulmonary embolism for which she was anticoagulated with warfarin. There was no history of trauma.\nOn examination she was haemodynamically stable. Her abdomen was generally tender, maximal tenderness being in the left hypochondrium and left lumbar region, associated with some guarding and rigidity. Bowel sounds were present and the rectal examination was unremarkable.\nThe blood tests revealed normal haemoglobin, marginally raised white cell count (12.5) and C- reactive protein (25.3), and a grossly deranged International Normalised Ratio (INR) of 8.9. Her renal and liver functions function tests were within normal limits. An erect Chest X-ray and supine abdominal films were both unremarkable. Computed Tomography (CT) Scan showed a long abnormal loop of thick walled jejunum with a small amount of free fluid in the intraperitoneal cavity (Figure and ).\nA diagnosis of spontaneous intramural haematoma of the jejunum was made. She was treated conservatively with nil by mouth, intravenous fluids, and nasogastric suction. Fresh frozen plasma and vitamin K were given to normalise her clotting parameters. Her symptoms subsided gradually over the next couple of days and she was gradually started on fluid and diet. The clotting parameters normalized and she was discharged home on normal diet six days later.
