Ultrasonographic confirmation of a space-occupying lesion in the brain of a horse: choroid plexus papilloma.
Abstract: Intraoperative brain ultrasonography is commonly used clinically
in human and canine neonates (Johnson and Rumack 1980;
Babock and Han 1981; Cappe and Lam 1985; Hudson et al. 1990,
1991) and a single report exists of its use to assist in defining
hydrocephalus in an equine neonate (Foreman et al. 1983). This
technique has also been reported to be clinically useful in human
adults (Rubenstein et al. 1984) and ultrasound-guided brain biopsy
has also been described in mature dogs (Thomas et al. 1993).
%ours of the central nervous system in the horse are
extremely rare, with the exception of pituitary adenomas (Cotchin
1977). There are many reports of choroid plexus papilloma in dogs
(Whitbread and Skerritt 1980; Chenier et al. 1983; Ribas et al.
1989; Hammer et al. 1990) and man (Gradin et al. 1983, Girardot
et al. 1990); however, only one documented case in the horse could
be found in the literature (Haghdoost and Zakarian 1985) despite
their existence being referred to by Fankhauser et al. (1974).
This report describes a choroid plexus papilloma in a horse,
emphasising the use of intraoperative ultrasonography to
determine the location and size of the lesion, a technique which
has not been reported in mature horses.

This research investigates the use of intraoperative ultrasonography for identifying a brain lesion, specifically a choroid plexus papilloma, in a mature horse. The study underlines the practicality of this approach not yet reported in adult equines.
Background
- The use of intraoperative brain ultrasonography is a common practice in human and canine neonates. Its application helps in detailing conditions like hydrocephalus in an equine neonate. This method has also usefulness in adult humans.
- Ultrasound-guided brain biopsy is another technique in use and has been successfully performed on mature dogs.
- Brain tumors, except pituitary adenomas, are remarkably rare in horses. A high frequency of choroid plexus papilloma reports exists for dogs and humans, whereas only one documented case was found for horses in previous literature, despite its known existence.
The Study
- The study describes the case of a horse diagnosed with a choroid plexus papilloma. The central focus is the use of intraoperative ultrasonography for determining the location and size of the lesion.
- The process involved using ultrasonography during surgery to provide a real-time image of the brain, allowing for accurate assessment of the tumour’s position and dimensions.
- The procedure is highlighted as a novel technique, as its use in mature horses has not been previously reported in the research.
Significance
- The research adds a new dimension to the use of intraoperative ultrasonography, demonstrating its successful application in mature horses apart from neonates.
- The outcomes of this research could pave the way for more systematic and detailed use of this technique in equines, especially in light of the rarity of brain tumors in this species.
- The study also emphasizes the potential for extended research and application of ultrasound-guided procedures in not only diagnosing but also treating brain conditions in horses.
