“…Gastrointestinal leiomyosarcomas can be hyperechoic or hypoechoic. Echo-free spaces due to liquefactive necrosis are frequently seen, in such a case, an echogenic rim is demonstrable [7,8]. When a central cavity communicates with the intestinal lumen, acoustic shadows from the air in the cavity can be shown.…”

“…One reason for such a large tumor in the case reported herein is the exophytic growth of the LMS. Smooth muscle-originating tumors of the gastrointestinal tract frequently extend transmurally thus obstructing the intestinal lumen ( 13 , 22 ), although, sometimes they bulge out of the serosa in an exophytic fashion ( 13 ). These tumors usually then lead to obstructive gastrointestinal symptoms, which could enable the owners to recognize symptoms of the tumors before they grow to an enormous size, except in cases where a tumor occurs in the cecum and is positioned in such a way that it does not limit the passage of intestinal contents ( 6 ).…”

“…The jejunum is one of the most commonly affected regions of the gastrointestinal tract affected by LMS ( 8 , 9 ). The jejunal muscularis propria is usually involved, and the tumors often grow into the bowel lumen, thus inducing obstructive gastrointestinal symptoms, such as the retention of intraluminal gas or fluid ( 10 – 13 ). Several retrospective studies have reported the clinical and morphological characteristics, diagnosis, and prognosis of canine intestinal LMS ( 14 – 17 ).…”

Case Report: Giant Multiloculated Pseudocystic Jejunal Leiomyosarcoma in a Dog: Atypical Morphologic Features of Canine Intestinal Leiomyosarcoma

A 10-year-old intact female Rottweiler dog weighing 29 kg presented with 2 days history of vomiting, anorexia, and lethargy to KonKuk University Teaching Hospital, Seoul, South Korea. Ultrasonography and computed tomography (CT) scannings revealed a well-demarcated, large mass (29 × 19 × 11 cm) with numerous fluid-filled cavities. Metastases to adjacent lymph nodes were also identified on CT. This large mass and the affected intestinal segments were excised for palliative purposes. Postoperatively, the dog recovered uneventfully without any complications. The cut surface of the mass showed an exophytic growth pattern of multiloculated cystic lesions filled with serosanguineous fluid, large cavities filled with necrotic exudate, and fistulous connections between the intestinal lumen and the necrotic cavity in the mass. On histopathology, the mass was a spindle cell neoplasm expanding from the jejunal muscular layer and with pseudocystic changes. Additional immunohistochemical analysis using antibodies against smooth muscle actin, desmin, and CD-117 demonstrated that the mass was consistent with a leiomyosarcoma. Six months post-operatively, plain radiography revealed an abdominal mass, suspected to be recurrence from jejunal leiomyosarcoma. The owner decided to euthanize the dog due to financial constraints. This case report describes the atypical morphology and clinical progression of a large canine jejunal leiomyosarcoma, which had similar clinical features as those of human leiomyoma and leiomyosarcoma.

“…The most probable diagnosis was gastric leiomyoma or leiomyosarcoma, with necrotic areas explaining the existence of the cystic zones detected by ultrasonography. [6][7][8] The existence of an aberrant pancreas was a surprise finding, given its size and the sonographic appearance. This case clearly shows the value of ultrasonography undertaken with fluid filling the gastric cavity in the diagnosis of pathological conditions of the stomach.…”

Aberrant pancreas is a relatively rare condition, and generally lacks clinical importance. Given its small size and the fact that it is most frequently located in the stomach and small intestine, its ultrasonographic appearance has not yet been described. This article presents a case of aberrant pancreas in the stomach. It was detected by abdominal ultrasonography of the wall of the fluidfilled stomach. CASE REPORTFIGURE 3. Pancreatic acini (thin arrows) and dilated pancreatic ductus (broad arrows) can be observed among the muscle fibers. JOURNAL OF CLINICAL ULTRASOUND
