A urinalysis and abdominal ultrasound were performed to further investigate the bladder mass. Nematode larvae were identified in the urine, termed microfilaruria, while a caudal abdominal mass was found on ultrasound impinging on the urethra. Fine-needle aspirate of the abdominal mass revealed malignant neoplasia. A SNAP 4Dx of the peripheral blood was positive for\n                    <jats:italic>Dirofilaria immitis<\/jats:italic>\n                    antigen and a modified Knott\u2019s test confirmed\n                    <jats:italic>D immitis<\/jats:italic>\n                    larvae. The patient was euthanized owing to poor prognosis, and multiple masses were found within the abdominal cavity that, based on histopathology and immunohistochemistry, were diagnosed as poorly differentiated sarcoma. Hemorrhage, secondary to the abdominal mass, was considered the primary cause of microfilaruria.\n                  <\/jats:p>","DOI":"10.5326\/jaaha-ms-7457","type":"journal-article","created":{"date-parts":[[2025,1,6]],"date-time":"2025-01-06T15:56:19Z","timestamp":1736178979000},"page":"12-14","source":"Crossref","is-referenced-by-count":1,"title":["Microfilaria in the Urine of a Dog with Concurrent Urinary Bladder Sarcoma"],"prefix":"10.5326","volume":"61","author":[{"given":"Nicole","family":"Schlette","sequence":"first","affiliation":[{"name":"From the Department of Veterinary Clinical Services, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (N.S., A.H., D.H.);"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erin","family":"Burton","sequence":"additional","affiliation":[{"name":"Department of Veterinary and Biomedical Sciences, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (E.B.); and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amber","family":"Harris","sequence":"additional","affiliation":[{"name":"From the Department of Veterinary Clinical Services, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (N.S., A.H., D.H.);"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kendall","family":"Langsten","sequence":"additional","affiliation":[{"name":"Department of Veterinary Population Medicine and Veterinary Diagnostic Laboratory, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (K.L., E.O.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik","family":"Olson","sequence":"additional","affiliation":[{"name":"Department of Veterinary Population Medicine and Veterinary Diagnostic Laboratory, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (K.L., E.O.)."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Heinrich","sequence":"additional","affiliation":[{"name":"From the Department of Veterinary Clinical Services, College of Veterinary Medicine, University of Minnesota, St. Paul, Minnesota (N.S., A.H., D.H.);"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3280","reference":[{"issue":"4","key":"i1547-3317-61-1-12-b1","series-title":"Trends Parasitol","first-page":"168","article-title":"Public health issues concerning the widespread distribution of canine heartworm disease","volume":"26","author":"Lee","year":"2010","unstructured":"Lee\n              ACY,\n            \n            \n              Montgomery\n              SP,\n            \n            \n              Theis\n              JH,\n            \n            \n              Blagburn\n              BL,\n            \n            \n              Eberhard\n              ML.\n            \n          \n          Public health issues concerning the widespread distribution of canine heartworm disease.
