Summary
A rare fungal brain abscess caused by Pseudallescheria boydii occurred in a woman using prednisolone for rheumatoid arthritis. Despite aggressive treatment, the infection proved fatal, highlighting the risks of opportunistic infections in immunocompromised patients.
Area of Science:
- Mycology
- Infectious Diseases
- Neurology
Background:
- Pseudallescheria boydii is an opportunistic fungus.
- Long-term corticosteroid use, such as prednisolone, can increase the risk of fungal infections.
- Rheumatoid arthritis patients on immunosuppressive therapy are susceptible to opportunistic pathogens.
Purpose of the Study:
- To describe the clinical and radiological characteristics of a Pseudallescheria boydii brain abscess.
- To highlight the challenges in treating invasive fungal infections in immunocompromised individuals.
- To underscore the potential severity of Pseudallescheria boydii infections.
Main Methods:
- Case report of a middle-aged woman with a right frontal brain abscess.
- Review of clinical presentation, radiological findings, and treatment course.
- Analysis of treatment outcomes including surgical intervention and antifungal therapy.
Main Results:
- The patient presented with a right frontal abscess after two years of prednisolone treatment for rheumatoid arthritis.
- Despite surgical excision and intravenous antifungal treatment, the patient succumbed to the infection within seven weeks.
- Radiological imaging confirmed the abscess and its progression.
Conclusions:
- Pseudallescheria boydii brain abscess is a rare but potentially fatal complication in immunocompromised patients.
- Aggressive multimodal therapy may not always be successful in eradicating the infection.
- Early recognition and prompt treatment are crucial, but outcomes can be poor.

01:26Brain Abscess l: Introduction
47
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...

01:22Bacterial Meningitis I: Introduction
31
Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...

01:26Bacterial Meningitis II: Pathophysiology
45
Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

01:22Cerebral Edema ll: Pathophysiology
31
Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this...
