Summary
Progressive ethmoidal haematoma (PEH) is a serious condition in horses. Surgical excision offers a chance of long-term resolution, but recurrence is a significant concern.
Area of Science:
- Veterinary Medicine
- Equine Surgery
- Pathology
Background:
- Progressive ethmoidal haematoma (PEH) is a condition affecting horses.
- This study investigates the diagnosis and outcomes of PEH in equine patients.
Purpose of the Study:
- To analyze the clinical presentation, diagnostic methods, and treatment outcomes for progressive ethmoidal haematoma in horses.
- To evaluate the efficacy of surgical excision versus conservative management for PEH.
Main Methods:
- Diagnosis involved history, clinical signs, endoscopy, and radiography.
- Histological confirmation was performed in 10 cases.
- Treatment strategies included conservative management and surgical excision.
Main Results:
- 14 horses diagnosed with PEH, with unilateral lesions in 78% and bilateral in 22%.
- Conservative treatment had a low success rate, with 3 of 4 horses euthanized due to progression.
- Surgical excision resulted in recurrence in 3 of 8 horses, while 2 had no recurrence within 60-72 months.
Conclusions:
- Progressive ethmoidal haematoma presents a diagnostic challenge in horses.
- Surgical intervention for PEH shows variable success rates, with a notable risk of recurrence.
- Further research into optimal treatment strategies for PEH is warranted.

Epistaxis
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
