CT of the head and neck, plain and post contrast – The computed tomography of the head reveals a non-uniformly enhancing & soft tissue attenuating mass lesion of 1.5 cm diameter with aggressive osteolysis in the left maxilla at the base of the zygomatic arch. Infiltrative growth with expansion into the left orbita is noted. The mid- and caudal portion of the zygomatic arch as well as the temporomandibular joint are within normal limits.
The left medial retropharyngeal and sbmandibular lymph nodes present moderate enlargement with non-uniform contrast enhancement.
Mild enlargement of the left tonsil is noted. The arytenoid cartialges present mild generalized and symmetric swelling. A mild accumulation of fluid is seen within the ventral aspect oft he larynx.
Several teeth are absent. The axial skeleton presents the expected geriactric changes.
Differential diagnoses include fibrosarcoma, osteosarcoma, squamous cell carcinoma, osteochondrosarcoma, lymphosarcoma and other.
Consider full tumor staging including biopsy, FNA of the regional lymph nodes and 3 view chest radiographs as well as abdominal ultrasound prior to therapeutic measures.
Therapeutic options may be adjusted accordingly and include chemotherapy for possible lypmhoma or other as well as surgery and radiative treatment.
Surgical resection with safety margins would require partial leftsided hemimaxillectomy as well as exenteration of the left orbita.
