The case is reported of a woman with a mucin producing lobular carcinoma of the breast with metastases to many bone sites, whose terminal neurological illness was the result, not of cerebral metastases, but of cerebral infarcts. These were caused by emboli of mucin and emulsified fat, originating in bone metastases. The pathogenesis of this embolism is compared with that of traumatic fat embolism. Attention is drawn to this process because emboli of this type have never been reported and because this distant nonmetastatic effect of carcinoma may have been overlooked in other cases. It is suggested that this mechanism should be considered in the diagnosis of otherwise obscure cerebral infarction.

A 41-year-old man was diagnosed with a solitary fibrous tumor (SFT) of the pleura in the posterior mediastinum. Despite two surgeries for excision, the SFT recurred and progressed with direct invasion of the chest wall and bone metastases. He was hospitalized because of cerebral infarction and presented with recurrent severe hypoglycemia fourteen years later. High-molecular-weight (HMW) insulin-like growth factor II (IGF-II) was identified in the serum and tumor using Western blotting and immunohistochemistry. These findings suggested that the cause of the recurrent severe hypoglycemia was SFT production of HMW IGF-II, a mediator of non-islet cell tumor-induced hypoglycemia (NICTH).

A 65-year-old man with disseminated bone metastases of prostate cancer was referred for Ga-PSMA-HBED-CC-PET/CT (short PSMA-PET/CT) to exclude visceral metastases before treatment of bone metastases with Ra-dichloride. Apart from disseminated bone metastases, PSMA-PET/CT revealed a focal cerebral tracer uptake in the right frontal lobe highly suspicious for cerebral spread. According to patient history, a cerebral infarction occurred 14 days before PSMA imaging in corresponding localization confirmed by MRI scanning. This case demonstrates the possibility of false-positive finding of cerebral metastases in PSMA-PET early after stroke.
