Neurothekeoma of tongue in a 15-year-old girl. Neurothekeoma of tongue in a 15-year-old girl. Contrast-enhanced axial CT scan (A) and axial T1-weighted (B), axial T2-weighted (C), and contrast-enhanced fat-suppressed coronal T1-weighted (D) MR images shows a relatively well-defined round soft-tissue mass (arrows) in the midline dorsal tongue. Compared with the adjacent normal intrinsic tongue muscle, the tumor shows isointense signal intensity and hyperintense signal intensity on T1-weighted (B) and T2-weighted (C) MR images, respectively. The attenuation of the tumor was isoattenuated to tongue muscle on precontrast CT scans (not shown). Also noted on T2-weighted MR image are hypointense interlacing septa within the tumor (C). After contrast enhancement, CT (A) and MR imaging (D) shows homogeneous moderate enhancement within the tumor.E, Axial FDG-PET-CT image shows a high FDG uptake within the tumor with a maximal SUV of 5.4.F, Photomicrograph shows the tumor composed of lobules of well-circumscribed oval-to-spindle neoplastic cells in a partly myxoid stroma and intervening attenuated fibrous connective tissue (hematoxylin-eosin, original magnification × 100).
