Intracranial collision metastases of prostate and esophageal carcinoma
Collision tumors are found when two pathologic tumor types are intermingled into a single location. Although these lesions have been reported in cases of metastases to primary intracranial tumors, there are very few case reports indentifying collision of primary malignancies outside of the central nervous system (CNS). We report a case of intracranial collision metastases to the brain with prostate and esophageal malignancies as the primary non-CNS tumors.
