Pituitary Metastatic Composite Tumors: A Case Report with Next-Generation Sequencing and Review of the Literature
Radiographic imaging of tumor progression preoperatively. T1-weighted sequence magnetic resonance imaging with contrast presented in axial, coronal, sagittal, and axial planes, respectively. Imaging demonstrates growth of the previously described mass with further encasement of the left cavernous internal carotid artery (a) with superior extension (b) with further effacement of the third ventricle (c). A subcentimeter-enhancing, spherical, paraventricular, left occipital lesion is apparent (d). The sellar mass now measures with a total estimated volume of 22.7 mL. Yellow boxes highlight the tumor of interest. Green box highlights an occipital lesion.
