RESUMEN
ABSTRACT: An 81-year-old man with known metastatic prostate cancer with recent biochemical progression underwent a PSMA PET/CT ( 18 F-piflufolastat) for restaging. Review of the images demonstrated an acute or chronic left cerebral convexity subdural hematoma on CT with corresponding radiotracer activity throughout the collection on PET. Analysis of the patient's prior imaging showed that this subdural hematoma had significantly increased in size when compared with a head CT obtained 2 months prior. The patient was referred to a nearby emergency department and underwent repeat imaging and subdural drain placement. Unfortunately, the patient died secondary to rapid reaccumulation of subdural blood products after intervention.

Hepatic arterial infusion (HAI) pumps are a specialized therapeutic modality designed to deliver high dose local chemotherapy to hepatic metastases in carefully selected patients resulting in improved survival, with patients living an average of 2 years longer than those who did not receive HAI pumps. While beneficial, these chemoinfusion pumps require a multidisciplinary approach to ensure safe and effective treatment for the patient. Here, we present a case where scintigraphic evaluation by the nuclear medicine department directly affected management of a patient with a hepatic arterial infusion pump. Variant vascular anatomy was initially discovered on the postoperative Tc-99m MAA SPECT/CT and was ultimately embolized by interventional radiology prior to initiation of chemoinfusion. This case report demonstrates the utility of obtaining nuclear medicine scintigraphy prior to chemoinfusion in patients with hepatic arterial infusion pumps.
