Periodic radiological evaluation of the patient.

Status and duration of OAM→	Month/Year →	MRI Neck		CT Neck/PNS/Brain
Beginning of OAM and ongoing chemotherapy	2011	03-06-2011	Abnormally altered signal intensity is seen in the halt of the tongue involving the anterior, middle, and posterior parts measuring 4.5 × 6.0 × 3 cm (SI × AP × ML). This is hypointense on T1W and hyperintense on STIR sequence. Deviation of the tongue is seen	–
End of chemotherapy	2011	05-08-2011	An area of altered signal intensity involving the anterior third of the tongue on the left side 2.7 × 4.0 cms suggestive of residual disease. As compared to previous MRI scan dated June 03, 2011, the lesion has significantly regressed in size and extent.	–
1 Y	2012	–		20-12-2012	No residual/recurrent lesion, a 2.5 × 1.9 cm low soft tissue lesion with tiny calcific foci within is seen in the occipital scalp without erosion of adjacent bone, represents a sebaceous cyst.
5 Y	2016	–		04-05-2016	Myocutaneous flap with fatty infiltration within is seen at the site of the tongue. Focal severe narrowing of the left ICA at the origin due to calcified plague.
11 Y	2022	–		07-07-2022	Multiple calcified hypodense lesions largest 5.6 × 4.7 × 7.6 cm in left occipital scalp region – likely benign etiology -? Calcified sebaceous cysts.
12 Y	2023			8-04-2023	PET CT- Three subcutaneous nodular lesions in the scalp- likely benign/ calcified nodular scalp. No abnormality detected elsewhere in the body.
