Summary
This case study highlights a rare instance of cerebral sparganosis mansoni, a parasitic brain infection, diagnosed via biopsy a decade after initial exposure. Early CT scans were misread, underscoring diagnostic challenges.
Area of Science:
- Neurology
- Infectious Diseases
- Parasitology
Background:
- Cerebral sparganosis mansoni is a rare parasitic infection of the brain.
- Accurate diagnosis can be challenging due to non-specific imaging findings.
Observation:
- A 62-year-old male presented with a 10-year history of motor aphasia and right hemiparesis.
- Brain imaging revealed left cerebral hemisphere atrophy, ventricular enlargement, and ring-enhanced lesions.
- Initial diagnosis considered cerebral infarction and meningioma.
Findings:
- Histopathological analysis of a left frontal biopsy confirmed cerebral sparganosis mansoni.
- The biopsy was performed concurrently with meningioma removal.
Implications:
- This case underscores the importance of considering parasitic infections in the differential diagnosis of complex neurological presentations.
- Delayed diagnosis of cerebral sparganosis is possible, even with characteristic but ambiguous imaging findings.
- Improved diagnostic criteria and awareness are crucial for timely and effective treatment of cerebral sparganosis.

01:26Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
01:26Brain 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,...
01:27Cryptococcal 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,...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:29Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
