Study Notes
Alimentary System Pathology
- Overview: This presentation covers selected cases of alimentary system diseases in animals.
Case 1
- Signalment: Male, 6-month-old Irish Setter dog.
- History: Presented with chronic regurgitation of solid meals, progressive emaciation, dyspnea, and coughing.
- Diagnosis: Persistent right 4th aortic arch and megaesophagus.
- Respiratory Signs: Aspiration of food during regurgitation (aspiration pneumonia).
Case 2
- History: Rumen from a steer that died after being sick for two days. The animal exhibited drowsiness and was treated with antibiotics. The diet consisted of pasture, hay, french fries, and grains
- Diagnosis: Multifocal hemorrhagic infarcts.
- Condition: Mycotic rumenitis
Case 3
- Signalment: Male, 5-year-old Great Dane.
- History: Dog presented with severe acute abdominal pain and vomiting; the animal died despite treatment. Abdomen markedly distended at necropsy.
- Abnormalities: Stomach markedly dilated (filled with fluid and gas), serosa congested, spleen engorged, displaced to the right, and V-shaped.
- Diagnosis: Gastric dilation and volvulus.
Case 4
- Signalment: 3-month-old female Mastiff.
- History: Presented with severe abdominal pain and vomiting; died despite treatment. Abdomen markedly distended at necropsy.
- Possible Causes: Any intestinal obstruction (foreign bodies, displacements, stenosis, atresia, paralytic ileus).
- Diagnosis: Small intestine: Intussusception
Case 5
- Signalment: 18-month-old female bovine.
- History: Presented due to poor body condition and diarrhea.
- Morphologic Diagnosis: Severe, multifocal ulcerative stomatitis and esophagitis
Ileum Changes
- Findings: Peyer's patches and overlying epithelium are necrotic and covered by blood.
- Differential Diagnoses: BVD, MCF, Rinderpest.
Case 7
- History: Lamb euthanized due to severe neurological signs; animal was in excellent nutritional condition.
- Differential Diagnoses: Enterotoxemia and intestinal volvulus.
Case 2 (Weimaraner)
- Signalment: Female, 13-year-old Weimaraner.
- History: Presented for anorexia, depression, vomiting, melena, and emaciation.
- Lab Results: Increased BUN and creatinine, regenerative anemia.
- Morphologic Diagnosis: Focal, ulcerative stomatitis (oral ulcer).
Additional Topics:
- Other Stomatitides: Issues concerning lips, pharynx, tongue, gums, tonsils, and palate.
- Cheilitis: Can be due to ORF (contagious ecthyma).
- PPR: Infectious disease in ruminants.
- Foot-and-Mouth Disease (FMD): Disease affecting cloven-hoofed animals. Causes lesions in the mouth.
- Malignant Catarrhal Fever (MCF): Characterized by skin and mucous membrane lesions.
- Johne's Disease: Infectious disease in ruminants.
- Bovine Viral Diarrhea (BVD): Disease characterized by various signs and tissue changes.
- Salmonella: Bacterial infection with several clinical syndromes. Affects multiple tissues and organs.
- Wooden Tongue: Veterinary condition affecting the tongue.
- Lumpy Jaw: Bacterial infection of jaw in ruminants.
- Oral Papillomas: Benign tumors of the oral cavity.
- Oral Neoplasia: Malignant oral tumors in dogs and cats. Include squamous cell carcinoma (SCC), melanoma, fibrosarcoma, and osteosarcoma
- Causes of Cleft Palate: Can be hereditary or due to teratogenic toxins (drugs, environmental toxins)
- Congenital Jaw Anomalies: Agnathia (absence), brachygnathia( shortened), and prognathia (elongated)
- Brachygnathia Inferior: Characterized by a shortened lower jaw.
- Prognathia Inferior: Characterized by a prolonged lower jaw.
- Hepatic Lipidosis: Abnormal accumulation of triglycerides in hepatocytes.
- Congestive Hepatopathy: (Nutmeg Liver) Liver dysfunction due to venous congestion, commonly linked to heart failure.
- Liver Necrosis: Death of liver cells due to various causes; can be periportal or centrilobular.
- Fibrosis: A general response of the liver to injury. Scar tissue formation.
- Cirrhosis: End-stage liver damage; characterized by scarring and nodular regeneration. Indicates irreversible damage.
- Hepatitis: Inflammation of the liver. Viral and bacterial causes.
- Rift Valley Fever: Viral disease causing abortion and neonatal death in ruminants, often with liver necrosis.
- Bacterial Hepatitis: Liver inflammation caused by bacteria (e.g., Campylobacter fetus, Campylobacter jejuni).
- ...Multiple additional conditions and diagnoses associated with various gross and microscopic presentations of organ pathology, along with etiology are present in this presentation.
