MR-guided Laser Induced Thermal Therapy (LITT) is a procedure for intracranial tumors. Minimal data exists regarding post-procedure lesion volume changes. ⋯ The response of intracranial lesions to LITT demonstrates a peak in volume at the IPA time point with decreased IPA inter-rater reliability. We recommend that conclusions about intracranial lesion size post-LITT be made at least 24 hours post-LITT rather than immediately after LITT.

Photodynamic therapy (PDT) is a minimally invasive treatment modality which has great clinical implications, especially in head and neck oncology. Post-operative swelling is a well-documented consequence of PDT. It is paramount the airway remains patent for these patients. A tracheostomy remains the gold standard treatment modality for base of tongue tumours susceptible to post operative PDT inflammation, which can lead to a compromised airway. We have carried out a retrospective study to outline the airway management strategies employed for head and neck cancer patients treated with PDT and suggest recommendations for future management. ⋯ Airway management is vital when planning PDT treatment for tongue based tumours. Consider a more conventional approach when the lesion being targeted is located at a higher risk site: Floor of mouth/posterior tongue/tongue base or when multiple oral sites are being treated.
