Non-Invasive Diagnostic Imaging - Ultrasound Case Study

Posted: 2012-06-28

Bear is a lovely 5 year old neutered male Husky cross that acutely developed diarrhea containing significant amounts of blood. At the time, our office was unfortunately closed, and he visited a local emergency hospital. Other than being slightly dehydrated, with minor changes on his full blood profile, his physical examination was normal. Abdominal radiographs (x-rays) were therefore performed at this time, to rule out an intestinal blockage or other obvious causes. Radiographs demonstrated some mild gas dilation of the colon, with no other abnormal findings or evidence of obstruction. Because of the dehydration and low protein levels on his blood profile, he was hospitalized on intravenous fluids and antibiotics for presumed IBD (irritable bowel disease) or gastrointestinal upset. Bear improved on medications and IV fluids, with some improvement in the diarrhea and a more normal appetite. He was therefore discharged from hospital to continue on oral medications.

Bear presented to Westbridge the next morning for an abdominal ultrasound, as due to the extent of the hemorrhagic stool, a more exact final diagnosis was desired. Despite improving on supportive medications, and the radiographs showing no abnormal findings, the ultrasound revealed a large mass in the middle portion of his small intestine. See the images below:

Colour doppler ultrasound image of canine small intestine with large intramural mass. Image 1: Ultrasound image using colour doppler to demonstrate the vascularity (blood flow) in the tumor – the arrow points to blood vessels. This helps with surgical planning, to anticipate the amount of blood loss and the number of vessels that may have to be ligated. The transparent dots represent the outline of the tumor.

Dynamic flow image of canine small intestine with intramural mass. Image 3: Compare the dotted outline on the left (tumor) to the dotted outline on the right (normal loop of intestine).

Image 4: Ultrasound image showing a normal portion of intestine just in front of the tumor. This portion is significantly dilated with partially digested food, as it is having difficulty getting past the tumor. The dots outline the loop of intestine, and the arrow points to the food matter.

Image 5: Ultrasound image of the spleen, outlined by transparent dots. The arrow points to an abnormal growth on the spleen (the darker oval). This would be sampled during surgery, to ensure it was not of concern.

Because of the invasiveness of the intestinal tumor, the progressing bloody diarrhea, and his inability to eat, surgical exploration of the tumor was performed. In surgery, precisely as visualized by ultrasound, a large mass was found in the small intestine.

Intestinal leiomyosarcoma in a 5 year old Husky cross. Image 7: With the small intestine exteriorized, the tumor was very evident, as illustrated by the black arrow. Normal intestine is seen on either side of the tumor.

The tumor was removed in its entirety, along with three inches of normal intestine on either side to ensure that microscopic tumor cells were not left in the abdomen. The two sides of intestine were then sutured together – this procedure is called an anastamosis.

An intestinal anastamosis was performed, removing the tumor and 3 inches of normal intestine on either side. Image 8: Here you can see the portion of small intestine, including the tumor, that was removed.

Leiomyosarcoma incised to visualize small intestinal attachment. Image 9: Once outside of the abdomen, the tumor was cut in half to visualize its attachment to normal intestine..

The lesion on the spleen was inspected surgically, and turned out to be a completely benign area of extramedullary hematopoiesis – an area where red blood cells are being produced outside of bone marrow. Because of the large amount of blood lost through persistent hemorrhagic diarrhea, he required a blood transfusion after surgery to bring his red blood cell levels back to normal. By the next day, Bear was eating, bright, and active, with a completely normal blood count. Within two weeks, he was completely back to his normal self, eating, gaining weight, with completely normal bowel movements.

The section of intestine that was removed was sent to the lab for review by a pathologist. It came back as an uncommon tumor called an intestinal leiomyosarcoma. They are locally destructive and frequently cause obstruction. The reported metastatic rate (chance of spreading elsewhere in the body), when tumours are examined based on location, is 12% for jejunal masses – the lowest rate for this particular tumor. This was great news for Bear, as his tumor was located in the jejunum (the middle portion of the small intestine).
