Seeding of a cavernous angioma with Mycoplasma hominis: case report.
OBJECTIVE AND IMPORTANCE: To describe a unique case of hematogenous seeding of a cavernous angioma with the commensal organism Mycoplasma hominis. CLINICAL PRESENTATION: A 40-year-old female patient presented with a severe headache and acute left facial nerve palsy. Imaging studies revealed a right frontal mass lesion with characteristics of a cavernous angioma. INTERVENTION: The patient underwent a craniotomy for cavernous angioma resection. Purulent material was noted at the time of resection, and no hemorrhage was observed. Despite antibiotic therapy, the patient required repeat craniotomies for subsequent abscess treatment. M. hominis was identified as the pathogen. CONCLUSION: M. hominis is a rare cause of brain abscesses and can be difficult to eradicate. Cavernous angiomas can be seeded hematogenously.
