Patient: 74 year old |
History: 74 year old patient: Recurrent squamous cell carcinoma of the right pharynx, on chemotherapy. Monitoring treatment response. |
Image Size:[small][as-submitted]
|
Findings: Radiopharmaceutical: 14 mCi F-18 Fluorodeoxyglucose i.v. The current rotating MIP images (Fig. 1) demonstrate two areas of focal uptake in the neck, improved since the prior examination (Fig. 2). However, there is a new area of abnormal FDG activity in the right pelvis (Fig. 1). Axial PET-CT images confirm a metastatic lymph node in the left neck (Fig. 3), as well as uptake in the primary tumor in the right supraglottic larynx (Fig. 4). Additionally, the focal uptake in the pelvis corresponds to gas-containing inflammatory soft tissue and fluid in the right pelvis and presacral space (Fig. 5), abutting a thickened rectal wall (Fig. 6). |
Diagnosis: Right pelvic and presacral abscess, presumably due to a perforated anus or rectum. |
