Ultrasound changes in hepatic mast cell infiltration in dogs included a subjective increase in size, a diffuse increase in echogenicity, and one or more hypoechoic nodules. Ultrasound findings in the affected canine spleen included one or more hypoechoic nodules and a subjective increase in size. Two ultrasonographically unremarkable canine livers and one unremarkable spleen were found to be infiltrated by mast cells. The mast cell\u2010infiltrated feline spleen was subjectively increased in size, mottled, irregular, or contained nodules. The affected lymph nodes in both dogs and cats were hypoechoic or inhomogeneous, subjectively increased in size, and rounded. Gastrointestinal involvement in cats was characterized by a thickened ileocecocolic junction or colon with loss of wall layering. Mast cells were not found in the gastrointestinal tract in any dog. One dog with mast cell infiltrate of the kidneys had multiple hypoechoic nodules in the cortex that distorted the outer contour of the kidney. Although these findings are not specific to the disease in either species, abdominal ultrasound is considered a useful tool for determining the extent of disease in small\u2010animal patients with mast cell tumor if used in conjunction with histopathology or cytology.<\/jats:p>","DOI":"10.1111\/j.1740-8261.2004.04008.x","type":"journal-article","created":{"date-parts":[[2004,12,29]],"date-time":"2004-12-29T18:03:39Z","timestamp":1104343419000},"page":"51-57","source":"Crossref","is-referenced-by-count":62,"title":["Ultrasonographic findings in abdominal mast cell disease: a retrospective study of 19 patients"],"prefix":"10.1111","volume":"45","author":[{"given":"Amy F.","family":"Sato","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mauricio","family":"Solano","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,1,12]]},"reference":[{"key":"e_1_2_6_2_2","first-page":"231","volume-title":"Skin tumors of the dog and cat","author":"Goldschmidt MH","year":"1992"},{"key":"e_1_2_6_3_2","first-page":"365","article-title":"Mastocytosis","volume":"3","author":"Stein DH.","year":"1986","journal-title":"a review"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(85)50036-4"},{"key":"e_1_2_6_5_2","first-page":"72","article-title":"Canine and feline mast cell tumors","volume":"1","author":"Macy DW.","year":"1986","journal-title":"biologic behavior, diagnosis and therapy"},{"key":"e_1_2_6_6_2","first-page":"917","article-title":"Canine mastocytoma\u2014a review of clinical aspects","volume":"154","author":"Hottendorf GH","year":"1969","journal-title":"J Am Vet Med Assoc"},{"key":"e_1_2_6_7_2","first-page":"188","article-title":"Clostridial peritonitis associated with a mast cell tumor in a dog","volume":"188","author":"Clark DM","year":"1986","journal-title":"J Am Vet Med Assoc"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1177\/030098588201900603"},{"key":"e_1_2_6_9_2","first-page":"417","article-title":"Canine mastocytoma\u2014a report of one hundred cases","author":"Nielsen SW","year":"1958","journal-title":"Am J Vet Res"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/030098586800500202"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(90)50087-X"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(97)50007-6"},{"key":"e_1_2_6_13_2","first-page":"469","article-title":"Canine cutaneous mast cell tumor","volume":"21","author":"Patnaik AK","year":"1984","journal-title":"morphologic grading and survival time in 83 dogs"},{"key":"e_1_2_6_14_2","first-page":"936","article-title":"Prognostic factors for radiation treatment of mast cell tumor in 85 dogs","volume":"193","author":"Turrell JM","year":"1988","journal-title":"J Am Vet Med Assoc"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1973.tb06891.x"},{"key":"e_1_2_6_16_2","first-page":"23","volume-title":"Tumors in domestic animals","author":"Pulley LT","year":"1990"},{"key":"e_1_2_6_17_2","first-page":"503","volume-title":"Managing the veterinary cancer patient: a practice manual.
