“…98 Such tumor growth is not observed in other species of domestic animals (including small ruminants) that have a restrictive diaphragma sellae around the infundibular stalk, in which most primary pituitary tumors remain extradural. 92,95 Pituitary adenomas also can protrude dorsally toward the optic chiasm 91 and erode the surrounding sphenoid bone ventrally 91,92 ( Figure 9-2). 92,95 Pituitary adenomas also can protrude dorsally toward the optic chiasm 91 and erode the surrounding sphenoid bone ventrally 91,92 ( Figure 9-2).…”

“…It has been described that its anatomy is similar to that of ruminants . Review of published literature suggests that pituitary neoplasia is very rare in ruminants . The majority of these reports describe acidophil pituitary adenomas in sheep and goats, although chromophobe adenomas and carcinomas have been described in sheep and cattle .…”

A 14-year-old 80-kg castrated male Huacaya alpaca was evaluated because of a gradual onset of behavioral changes. The owner had perceived decreased feed intake and abnormal behavior during the 7 days before admission. Decreased feed intake had progressed to complete inappetence by 3 days before admission. The alpaca often was separated from the herd and was not observed to lie down on its own. No improvement was appreciated after treatment with tulathromycin before admission (dosage unknown). The alpaca was known to be vaccinated annually for rabies and clostridial diseases and was dewormed regularly (medications, dosage, and frequency unknown).On examination, the alpaca was obtunded and somnolent. Rectal temperature was normal (38.6°C). Heart rate was increased at 92 beats/min and respiratory rate was normal at 16 breaths/min. The alpaca was in good body condition. Mucous membranes were pink and capillary refill time was normal. Peripheral lymph nodes palpated normally. Appetite and gastrointestinal motility were poor. Urination and defecation were not observed during examination. The alpaca was ambulatory but had a tendency to walk compulsively and press its head and body against walls without directional preferences or circling. Cranial nerve reflexes, including menace response, were present and appeared within normal limits. Gait analysis indicated a slow pace with asymmetric hypermetria in the hindlimbs, with the left being more severely affected than the right. Spinal reflexes were difficult to assess but appeared normal. In sternal recumbency, the alpaca would lower its neck and press its nose against the ground. Initial neurologic evaluation localized disease to the prosencephalon.Clinical laboratory tests evaluated at admission included CBC, serum biochemical analysis (SBA), fibrinogen concentration, and blood ammonia concentration. Marked leukocytosis (37,110 cells/lL; reference range, 7,500-20,900 cells/lL), neutrophilia (33,028 cells/lL; reference range, 3,130-15,254 cells/ lL), and a regenerative left shift (band neutrophils, 371 cells/lL; reference range, 0-169 cells/lL) were observed on CBC. Abnormalities on SBA included hyperglycemia (281 mg/dL; reference range, 120-132 mg/dL), increased creatinine concentration (1.9 mg/dL; reference range, 1.4-1.7 mg/dL), hypophosphatemia (2.5 mg/dL; reference range, 4.9-7.2 mg/dL), hypoalbuminemia (3.3 g/dL; reference range, 3.7-4.2 g/dL), increased aspartate aminotransferase (AST) activity (365 U/L; reference range, 106-165 U/L), increased gamma-glutamyl transferase (GGT) activity (62 U/L; reference range, 5-20 U/L), and increased creatine kinase (CK) activity (2827 U/L; reference limits, 3-145 U/L). Serum fibrinogen concentration was increased (762 mg/dL; reference range, 100-500 mg/dL). Blood ammonia concentration was normal (16 lmol/L; references range, 0-30 lmol/L). An inflammatory or infectious disease process was suspected based on hyperfibrinogenemia and a leukocytosis characterized by neutrophilia with a regenerative left shift. Abnormalities on SBA we...
