case_images: Pretreatment imaging assessment: (A) thoracic computed tomography (CT)-scan showing a speculated pulmonary nodule (red narrow); (B, C) cranial magnetic resonance imaging (MRI) showing a mass infiltrating the left infratemporal fossa (B) and pachymeningitis (C); (D, E) positron emission tomography (PET) scan showing hyperfixation of the ear, nose and throat (ENT) tumor (D) and the anterior longitudinal vertebral ligament (E).

case_images: Due to deterioration in his general health status and active smoking, a thoracic computed tomography (CT) scan was performed and spiculated and multilobulated nodules and masses were identified on his lung parenchyma, the largest of which measured 27 mm (Fig. 1A). MRI of the face showed left infratemporal fossa infiltration measuring 36 mm in diameter extending medially to the parapharyngeal space with perineural infiltration along the V3 nerve and pachymeningeal enhancement around it (Fig. 1B and C). An 18-FDG positron emission tomography scan revealed hypermetabolism of this left parapharyngeal pseudo-tumoral lesion, hypermetabolism of pulmonary nodular opacities and condensations, and signs of spondyloarthropathy with clear enthesopathy of the anterior longitudinal ligament in front of 6 vertebrae and bilateral sternoclavicular inflammatory arthropathy (Fig. 1D and E).
case_images: Posttreatment imaging assessment: (A) thoracic CT-scan showing the disappearance of the pulmonary nodule; (B) cranial MRI showing clear regression of the ENT lesion.
