Summary:While schwannoma is one of the most common types of benign peripheral nerve tumors in adults, a very unique and specific variant of schwannoma, the intravascular variant, is exceedingly rare. There have only been three previously published cases of intravascular schwannomas. Here we describe a fourth case of an intravascular schwannoma in a 47‐year‐old man with an enlarging subcutaneous nodule on his posterior calf. This is the second case of an intravascular schwannoma contained within a vein. Also included is an overview of intravascular schwannomas, including a description and discussion of the histopathological diagnosis, differential diagnoses, and schwannoma variants.
