case_images: A 31-year-old male with a history of a jaw tumor presented with the right-sided headache and vision loss. Axial view of a non-contrast CT scan of the head demonstrates a large, heterogeneous mass involving the right masticator space and extending superolaterally along the right temporal fossa (arrows).

case_images: A non-contrast computed tomography (CT) scan of the head was obtained and showed a large, heterogeneous mass involving the right masticator space and extending superolaterally along the right temporal fossa with destruction of the right middle cranial fossa floor [Figure 1].
case_images: A 31-year-old male with a history of a jaw tumor presented with the right-sided headache and vision loss and subsequently found to have a large, heterogeneous mass involving the right masticator space on CT scan. Axial view of a contrast-enhanced MRI of the face performed for further characterization shows a large, multilocular cystic mass with avidly-enhancing nodular soft-tissue components associated with the right temporal fossa and extending medially to involve the clivus (white arrows), sphenoid buttress (blue triangle), and greater wing of the sphenoid (red star).

case_images: There were additional pericentimeter, avidly-enhancing masses within the posterolateral aspect of the right globe, right frontal calvarium, and right optic strut [Figure 2].
case_images: A 31-year-old male presented with a jaw tumor and was subsequently diagnosed with ameloblastic carcinoma. Axial view of a CT scan of the chest performed for staging reveals several small cystic lesions within the imaged portion of the liver, including a lesion in the posterior right hepatic lobe with irregular margins and attenuation slightly greater than simple fluid (black arrow).

case_images: However, there were several small cystic lesions within the imaged portion of the liver, one of which demonstrated attenuation slightly greater than simple fluid [Figure 3].
case_images: A 31-year-old male presented with a jaw tumor and was subsequently diagnosed with ameloblastic carcinoma. Initial staging CT scan of the chest showed several small cystic hepatic lesions, including a suspicious cystic hepatic lesion in the posterior right hepatic lobe. A CT scan of the abdomen and pelvis was performed 3 months later. Axial view (a) shows rapid interval growth of the cystic hepatic lesions (white arrows). Coronal view (b) illustrates the extent of disease, with hepatic lesions in segments 2, 5, and 8 (white arrows).

case_images: A follow-up CT scan of the chest, abdomen, and pelvis obtained 3 months later showed a marked increase in size of the previously demonstrated hepatic lesions [Figure 4a and b]; the lesions demonstrated avid peripheral enhancement on MRI [Figure 5a and b].
case_images: A 31-year-old male presented with a jaw tumor and was subsequently diagnosed with ameloblastic carcinoma with suspected hepatic metastases. Axial view (a) of a contrast-enhanced MRI of the abdomen demonstrates multiple cystic hepatic lesions with irregular morphology and avid peripheral enhancement (white arrows). Coronal view (b) shows extensive disease involving multiple hepatic segments and abutting branches of the hepatic vein (white arrows).

case_images: A follow-up CT scan of the chest, abdomen, and pelvis obtained 3 months later showed a marked increase in size of the previously demonstrated hepatic lesions [Figure 4a and b]; the lesions demonstrated avid peripheral enhancement on MRI [Figure 5a and b].
case_images: A 31-year-old male presented with a jaw tumor and was subsequently diagnosed with ameloblastic carcinoma with suspected hepatic metastases. Contrast-enhanced MRI obtained at 1 year follow-up shows recurrence of the primary tumor with an increased size of an irregular central cystic component involving the clivus (white arrows) and invasion of the right maxillary sinus (red star). Hepatic metastases had also increased in size (not shown).

case_images: The patient remains on carboplatin and paclitaxel therapy with recurrence of the primary tumor and progression of metastatic disease at 1-year follow-up [Figure 6].
