Role of magnetic resonance imaging in evaluation of atypical case of craniopharyngioma.

Figure S1: Prenatal magnetic resonance imaging at the 34th gestational week. An expansive and heterogenous sellar and suprasellar expansive lesion is well-demonstrated, consistent with craniopharyngioma (asterisk). The hypothalamus, midbrain, and supratentorial ventricles are dislocated superiorly, the brainstem posteriorly, and the temporal lobes laterally. The tumor has a heterogeneous signal intensity, mostly presenting hyperintense signal in T2-weighted images; with areas of hypointensity in T1-weighted images and with no area of restricted diffusion. A, sagittal T2-weighted image; B, coronal T2-weighted image; C, axial T2-weighted image; D, T1-weighted image; E, Apparent diffusion coefficient map. Figure S2: Neonatal magnetic resonance imaging of craniopharyngioma. A, sagittal T1-weighted sequence after contrast, demonstrating the heterogeneous suprasellar tumor; B, axial T2-weighted sequence. Figure S3: Computed tomography image of the brain at the 4th year of life: the tumor presented many spherical lesions compatible with degenerative calcifications. Figure S4: Magnetic resonance imaging of the suprasellar tumor at the 5th year of life measuring 39 x 41 x 51 mm. A, sagittal T1-weighted sequence; B, axial T1-weighted image. Images captured after intravenous contrast. Figure S5: Brain magnetic resonance imaging at the 8th year of life: a heterogenous, well circumscribed suprasellar lesion, with irregular contrast enhancement in T1-weighted image (A). The lesion has round areas of low hypointense signal intensity in T2-weighted images within the lesion, which might represent areas of calcification (B). Figure S6: Three-dimensional reconstruction of magnetic resonance imaging of the brain and tumor, from the prenatal (left), neonatal (center), and 8th year of life (right). A, the coronal images; B, axial images; C, sagittal images. Table S1: Previous cases of fetal images of craniopharyngioma.
