Trial Title: Safety and Feasibility Study of Methylene Blue Photodynamic Therapy to Sterilize Deep Tissue Abscess Cavities

Study Design Characteristics:
- Allocation: NON_RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1
- Number of Arms: 6.0

Eligibility Criteria:
Inclusion Criteria:~* Adults 18 years or older~* If female, patient must have negative pregnancy test~* All patients with clinical symptoms (ex: fever, chills, pain, tachycardia, hypotension), laboratory (leukocytosis) and radiologic findings (thick walled, rim-enhancing collection with gas bubbles or air-fluid levels) compatible with an abscess that requires image-guided percutaneous drainage~* Abscess cavity diameters will be less than or equal to 8 cm. However, abscess can be complex or loculated~* Approval by the primary care team to pursue PDT and discuss enrollment with the patient~Exclusion Criteria:~* Pregnancy~* Lactation~* Allergy to contrast media, narcotics, sedatives, atropine or eggs~* Necrotic tissue that requires surgical debridement~* Severely compromised cardiopulmonary function or hemodynamic instability~* Thrombocytopenia (\<50,000/mm3)~* Uncorrectable coagulopathy~* Poor kidney function (serum creatinine \>3mg/dl)~* Lack of a safe pathway to the abscess or fluid collection~* Unable or unwilling to understand or to provide informed consent~* Unable or unwilling to undergo study procedures~* Patient unable to cooperate with, or to be positioned for the procedure~* Unable to comply with necessary follow up~* Abscesses greater than 8 cm in diameter, multiple separate abscesses in different locations, and abscesses not amenable to safe percutaneous image-guided drainage.~* Patient is currently taking serotonergic psychiatric medication
