Abstract

The central nervous system (CNS) is a rare but serious site of tuberculosis spread that manifests in three forms: meningitis, spinal arachnoiditis, and CNS tuberculoma. CNS tuberculoma, or intracranial tuberculous granuloma, is a caseating or non-caseating granulomatous reaction within the brain parenchyma that may mimic a brain tumor. We present the case of a 10-year-old male patient with a travel history to Western Africa who presented to our institution after his fourth tonic-clonic seizure over 2 months. MRI of the brain revealed a solitary cortical/subcortical enhancing intracranial mass with intralesional hemorrhage and mineralization, pathologically proven to represent a CNS tuberculoma. While rare, this etiology should be considered with the appropriate travel history and for which prompt treatment may improve outcomes in the pediatric population.

Abstract

Often complementary to clinical assessment, imaging of the brachial and lumbosacral plexus can be used to characterize plexus involvement by primary neoplasm, metastases, or conditions related to treatment. The imaging modality of choice, magnetic resonance (MR) without and with contrast, typically includes T1-weighted and fat-suppressed T2-weighted images. MR can delineate primary plexus neoplasms, including benign and malignant peripheral nerve sheath tumors, and accurately characterizes the extent of plexus involvement due to infiltrative malignancy. In cases in which there is clinical uncertainty between recurrent tumor and radiation injury, MR has been shown to be highly sensitive and specific. Positron emission tomography/computed tomography has also been shown to be useful in excluding recurrent tumor. MR imaging techniques that have been more recently investigated in plexus imaging, including diffusion-weighted imaging, isotropic three-dimensional imaging, diffusion tensor imaging, and fiber tractography, show potential to further complement clinical evaluation.
