Welcome to health care magic.
1.The report suggest there are postoperative features, and
soft tissue seen involving the tympanic cavity and mastoid antrum.
2.The suspicion in this case is in could be the regrowth of the previous pathology.
3.Non visualisation of the uncudo-malleolar articulation - which need to correlate with the previous scan - weather new findings or post operative change.
4.Comming to neck scan - the
lymph nodal enlargement - this can be seen in any infective / inflammatory and presence of any malignancy.
5.In this case an FNAC - fine needle aspiration cytology to assess the causative cells involving the growth for confirmation and treatment.
Good luck.
