Symptomatic cerebral histoplasmoma. Case report
Abstract:
A 53-year-old man, with a past history of a thoracotomy 7 years previously, developed seizures. A computerized tomography scan with contrast medium revealed a peripheral ring-like lesion in the anterolateral part of the right parietal lobe. Pathological evaluation of the resected lesion demonstrated it to be a histoplasmoma. Although rare, a histoplasmoma should be included in the differential diagnosis of a ring-shaped lesion in a patient with previous pulmonary disease.
Insights
A rare brain tumor called histoplasmoma caused seizures in a patient with a history of lung surgery. This finding highlights the importance of considering histoplasmoma in the diagnosis of ring-shaped brain lesions, especially in those with prior pulmonary disease.
Area of Science:
- Neurology
- Infectious Diseases
- Radiology
Background:
- A 53-year-old male with a history of thoracotomy presented with new-onset seizures.
- Cerebral imaging is crucial for diagnosing neurological conditions.
Observation:
- Computerized tomography (CT) scan with contrast revealed a peripheral ring-enhancing lesion in the right parietal lobe.
- The lesion's location and appearance suggested a neoplastic or infectious etiology.
Findings:
- Surgical resection and pathological examination identified the lesion as a histoplasmoma.
- Histoplasmoma, a fungal granuloma caused by Histoplasma capsulatum, is an uncommon cause of intracranial lesions.
Implications:
- This case underscores the importance of including histoplasmoma in the differential diagnosis of ring-enhancing brain lesions.
- Patients with a history of pulmonary disease, particularly endemic fungal infections, should be evaluated for intracranial histoplasmoma when presenting with neurological symptoms.
