Cecal vascular hamartoma causing recurrent colic in an Arabian mare

Area of Science:

• Veterinary Medicine
• Surgical Pathology
• Equine Health

Background:

• Recurrent colic and unexplained weight loss are common presenting complaints in equine practice.
• Intraluminal cecal masses can cause significant gastrointestinal distress in horses.
• Differential diagnoses for these clinical signs are broad, necessitating thorough investigation.

Observation:

• A 5-year-old mare presented with a history of recurrent colic and progressive weight loss.
• Diagnostic workup led to the identification of an intraluminal cecal mass.
• Surgical intervention was performed for mass removal.

Findings:

• Microscopic examination of the resected mass confirmed a diagnosis of vascular hamartoma.
• The mare experienced significant improvement in her general condition following surgery.
• A 6-month follow-up indicated sustained positive outcomes.

Implications:

• Vascular hamartoma, though rare, should be included in the differential diagnosis for horses exhibiting colic and weight loss.
• Surgical management can be curative for cecal vascular hamartomas.
• This case highlights the importance of considering neoplastic and vascular anomalies in equine gastrointestinal disease.
