From: Posterior fossa tuberculoma in a Huichol native Mexican child: a case report
Cranial magnetic resonance imaging of the tuberculoma and histopathologic studies of the surgical specimen. (A-B) T1-weighted and contrast-enhanced T1-weighted axial MRI revealed a large (61 × 69 × 62 mm) heterogeneous lesion that was contralaterally displacing the fourth ventricle and pons. (C-D) Sagittal views show an intensely gadolinium-enhanced lesion occupying the entire posterior fossa and causing hydrocephalus by compressing the fourth ventricle. (E) The surgical specimen comprised a caseous-appearing material. (F) Acid-fast bacilli observed by Ziehl–Neelsen staining (original magnification, ×100). (G) Lymphoplasmacytic inflammation containing epithelioid cells and multinucleated Langhans giant cells forming a granulomatous lesion. Hematoxylin and eosin staining (original magnification, ×10).
