Objective: Description of an infiltrating solitary hemangiosarcoma in the lumbal spine of a female Norfolk Terrier employing modern imaging techniques. Results of clinical and pathological examination are discussed.
Study design: Clinical case report.
Sample population: One nine-year-old female Norfolk Terrier.
Results: Clinical, neurological, ultrasonographic, laboratory and radiographic examinations revealed an abdominal mass as well as a lesion to the spine in the thoracolumbar area. By use of further diagnostic imaging techniques (medullography; computed tomography, CT; magnetic resonance imaging, MRI), the abdominal mass was localized cranially to the left kidney, and osteolysis of the first lumbar vertebra as well as a change of structure in the adjacent muscle was seen. Necropsy and histological evaluation performed after euthanasia led to the diagnosis of a solitary hemangiosarcoma and confirmed the site of tumour invasion as seen by CT and MRI.
Conclusions: A neoplastic lesion was precisely characterized through the combination of different imaging techniques without employing invasive methods.
Clinical relevance: Modern imaging techniques facilitate a precise judgement as to the extent of neoplastic disease and allow for a more accurate prognosis. The etiological diagnosis can only be made by histological examination.
