Brain Abscess l: Introduction

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,...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Amebiasis

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...

Cryptococcal Meningitis

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...

Angle Closure Glaucoma: Treatment

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Summary

A rare infratemporal fossa hydatid cyst caused rapid vision loss in a young patient. Prompt surgical removal and medical treatment led to complete visual recovery, highlighting the importance of timely intervention for this rare condition.

Area of Science:

Ophthalmology
Neurosurgery
Infectious Diseases

Background:

Hydatid cysts, caused by Echinococcus granulosus, are endemic in many regions, but infratemporal fossa involvement is exceptionally rare.
This case highlights the diagnostic challenges and management of a previously unreported location for hydatidosis.

Observation:

A 14-year-old female presented with acute proptosis and severe visual loss in the right eye over 10 days.
Radiological imaging revealed a parapharyngeal cyst compressing the optic nerve via the inferior orbital fissure.
The patient had a prior history of a frontoparietal hydatid cyst and intermittent albendazole treatment.

Findings:

Surgical excision of three cysts from the right maxillary sinus via Caldwell-Luc approach.
Intraoperative irrigation with hypertonic saline to eradicate parasite protoscolices.
Complete resolution of proptosis and restoration of vision post-operatively.

Implications:

Early surgical intervention is crucial for preventing irreversible damage and improving prognosis in infratemporal hydatidosis.
Continuous monitoring for recurrence in adjacent organs is essential due to the parasitic nature of hydatid disease.
This case underscores the need for high clinical suspicion and prompt management of rare parasitic infections presenting with neurological compromise.
