A 63-year-old male patient presented with a history of hoarseness of voice and dysphagia. This mass appears well circumscribed shows the intermediate signal onT1W axial image (a), hyperintense at T2-short tau inversion recovery coronal image (b), no contrast-enhancement at the post-contrast fat-saturated image (c) and sagittal computed tomography shows mass separate from tongue base (d).

Histopathology confirmed low-grade cribriform adenocarcinoma of tongue base [Figure 1].

An 84-year-old female patient presented with altered voice and dysphagia. Magnetic resonance imaging neck with contrast demonstrates a well-demarcated lesion with uniform hyperintensity on axial T1-weighted (a), homogeneous hyperintensity at T2-weighted sagittal (b) (arrows), suppression of signal on T2-short tau inversion recovery axial (c) and no contrast-enhancement with fat suppression on post-contrast coronal fat-saturated T1-weighted coronal (d).

The imaging findings were consistent with a large vallecular lipoma [Figure 2]. The patient did not opt for surgery due to other comorbidities and is stable under follow-up.

An 80-year-old male patient was referred for magnetic resonance imaging neck which showed an incidental 20 large vallecular cyst on the left and a 10-mm cyst on the right (arrows). This lesion appears well defined, reveals intermediate signal on T1-weighted axial image (a), homogeneous hyperintensity on T2-weighted axial (b) and T2-weighted coronal (c) and no contrast enhancement was revealed (d).

Both showed features of the benign cyst without any diffusion restriction or contrast-enhancement [Figure 3].

A 54-year-old female chronic smoker presented with few months history of progressive soreness of throat and right-sided throat pain. magnetic resonance imaging neck with contrast reveals a supraglottic tumor (47 mm x 20 mm x 30 mm) with large right vallecular component and supraglottic involvement with obliteration of right piriform sinus (arrows) on T2-weighted axial (a), marked infiltration with thickening of the epiglottis on T2-weighted sagittal (b), thickening of right aryepiglottic fold and tumor enhancement at post-contrast coronal fat-saturated T1 coronal (c).

The inferior component of the tumor is seen involving the right aryepiglottic fold with obliteration of the right piriform sinus [Figure 4].

A 52-year-old male presented with left neck lump and examination revealed a large vallecular mass with suspected tongue base malignancy. Axial T1-weighted (a), axial T2-short tau inversion recovery (b) and postcontrast fat-suppressed image (c) demonstrate large left vallecular mass arising from tongue base (arrows). Note of large left level-II lymph node (star).
