[|AI|]  Hello and welcome to Chat Doctor, Lumps at the base of skull need to be investigated. First an X-ray and/or CT scan of the head and neck region need to be done. Neck lesions can be due to soft tissue swelling or bony swelling. Imaging study will determine the site and origin of he lumps. After determining the site and origin of the lesions, the nature of the lump needs to be known, and thus an aspiration cytology can be planned. In this investigation, cells are aspirated from the lump, spread on glass slide and stained with appropriate stains. After determining the nature of the lump, appropriate management can be done. Consult your primary healthcare provider for further work up. Thanks and take care Chat Doctor.
