Inflammatory pseudotumor is a benign lesion of unknown etiology, which mimics neoplasms clinically and radiographically. It most commonly involves the lungs and orbits and is rarely reported in the central nervous system. We report a rare case of inflammatory pseudotumor located in the ventral junction of the medulla oblangta and cervical cistern, which has not been reported before as far as we know. A 61-year-old male presented with right arm weakness. MRI showed a mass located in the ventral junction of the medulla oblongata and cervical cisten. The patient was diagnosed as inflammatory pseudotumor(IPT) after surgical excision and histopathology. This tumor-like lesion was surrounding the bilateral intracranial segment of the vertebral arteries. No evidence of vascular invasion was observed. Complete surgical resection was achieved.
