Intravenous pyogenic granuloma in the internal jugular vein: A case report and literature review.

RATIONALE

Intravenous pyogenic granuloma (IVPG) is a special type of pyogenic granuloma, and its preoperative diagnosis is difficult. We report a rare case of IVPG that develops in the lumen of the internal jugular vein (IJV). Here, we analyze the imaging characteristics of present case and summarize the imaging characteristics of previous reported cases.

PATIENT CONCERNS

A 44-year-old man who presented with a growth in the IJV without any symptoms.

DIAGNOSES

A diagnosis of IVPG was made, based on the pathological examination after surgery.

INTERVENTIONS

The patient underwent surgery to excise the vein segment containing the neoplasm.

OUTCOMES

The patient did not present with any complications in the postoperative follow-up period.

LESSONS

For clinician, IVPG's preoperative diagnosis is difficult. Although histopathology remains the gold standard for diagnosis, the combination of multiple types of imaging examinations is necessary to rule out the differential diagnoses of IVPG.
