Ring-enhancing lesions in an immunocompetent patient

Area of Science:

• Neurology
• Infectious Diseases
• Radiology

Background:

• Ring-enhancing brain lesions are diagnostically challenging, particularly in immunocompetent individuals.
• Toxoplasma gondii typically causes encephalitis in immunocompromised patients (e.g., HIV/AIDS).
• Cerebral toxoplasmosis in immunocompetent hosts presents a diagnostic dilemma, mimicking neoplastic or fungal lesions.

Purpose of the Study:

• To highlight the diagnostic challenges of Toxoplasma encephalitis in an immunocompetent patient.
• To emphasize the importance of considering toxoplasmosis in the differential diagnosis of ring-enhancing brain lesions.
• To underscore the necessity of tissue diagnosis and multidisciplinary management.

Main Methods:

• Case report of an immunocompetent patient with toxoplasma encephalitis.
• Detailed radiological and clinical evaluation of multiple cerebral lesions.
• Histopathological examination for definitive diagnosis.

Main Results:

• The patient presented with atypical radiological findings and persistent clinical deterioration.
• Diagnosis was delayed due to ambiguous presentation, mimicking other pathologies.
• The case underscores the importance of considering Toxoplasma gondii.

Conclusions:

• Toxoplasma encephalitis can present atypically in immunocompetent hosts.
• Tissue diagnosis is essential for accurate identification of cerebral toxoplasmosis.
• Multidisciplinary management is critical for optimal patient outcomes.
