Focal haemorrhages were present within neuropyle of the spinal cord, with mild axonal swelling observed in ventral cord horns as well as in spinal nerves. Jpn J Vet Sci ; Jpn J Vet Sci. Haematological parameters and analysis of cerebrospinal fluid collected by cistern puncture did not reveal any abnormalities Table 1.
A 6 year—old Holstein cow was euthanized after a 3 week course of progressive paraplegia. A 6—year—old and kg nulliparous Holstein female with an implanted rumen fistula for the collection of ruminal fluid was initially observed by the caretakers with lrucosis ataxia and urinary incontinence.

In these cases, it has been shown that a careful morphological examination of the blood smear may distinguish between atypical mononuclear cells from other normal lymphocytes, thus providing an early diagnosis Ohshima et al.

Gross post—mortem findings revealed the presence of 4 to 6 small nodular masses, ranging in size from 1 to 5 cm, which were embedded in the walls of the small intestines but did not seem to adhere to adjacent tissues and did not appear to have perforated the mucosa or caused visible ulcers, or areas of haemorrhage.

J Vet Med Sci ; In a pathology study Ohshima et al. Bone and bone marrow necrosis associated with the calf form of sporadic bovine leukosis. Most reports describe a progressive loss of weight, decreased milk production, anorexia, diarrhea or constipation, which is associated with a generalized lymphadenopathy Ohshima et al.
Post—mortem examination revealed a localized form of lymphosarcoma with few 2—5 cm nodular tumors confined ivral the walls of the gastrointestinal tract, particularly in the abomasum. EBL affects cattle over 3 years of age and the clinical signs may vary depending on the location and development of neoplasia.
On cut surface, these masses were cream—colored with scarce areas of superficial haemorrhage and had a semi—firm consistency. The abomasal wall had several similar nodules as well as areas of diffuse wall thickening associated leucodis an irregularly shaped eroded reddened mucosa.
Bovija masses were observed in other organs including the spleen, liver, brain, lungs, heart and kidneys. This means the journal and Pontificia Universidad Javeriana cannot be held responsible for any ethical malpractice by the authors. Neither clinical nor paraclinical boovina confirmed the diagnosis during the clinical course of the disease in this animal.
The present cow had very few and small lesions detectable at necropsy for what would be expected with typical EBL, and they could have been easily missed by a quick and superficial rectal palpation.
Discussion Neither clinical nor paraclinical examinations confirmed the diagnosis during the virxl course of the disease in this animal.

Complete blood counts, biochemical profiles and analysis of the cerebrospinal fluid were reported within normal limits. In the current case, it is likely that insufficient time leucisis for tumors to grow—up to a size of antemortem clinical detection because of the rapid progression of the spinal cord compromise and posterior paralysis.
