Intravascular fasciitis of the scalp as a complication of ICP monitor placement: a case report and review of the literature

Background/Importance: There are only 56 documented cases of intravascular fasciitis, a rare variant of nodular fasciitis. Of these cases, only 2 involved the scalp. This lesion is amenable to surgical resection, making it important to differentiate it from soft tissue malignancies of the scalp. Clinical presentation: We report an unusual case of intravascular fasciitis involving the scalp at the site of an intracranial pressure (ICP) monitor of a 13-year-old male patient. The lesion was surgically excised with no recurrence upon 1-month follow-up. Conclusion: Intravascular fasciitis is a benign, reactive proliferation of soft tissue that may arise at sites of prior trauma. It appears as a soft, painless, mobile lesion, and immunohistochemical studies are required to differentiate it from malignant lesions. The standard of care is surgical resection of the lesion.
