Jugular foramen fibromatosis in a 3-month-old male.

A 3-month-old male with a chief complaint of episodic choking with feeds and a hoarse cry is presented. Left eye ptosis and asymmetric soft palate elevation were detected on physical examination. Fiberoptic examination showed a left vocal fold paresis and pooling of secretions in the pyriform sinuses. MRI demonstrated an ill-defined lesion at the left jugular foramen extending into the left carotid sheath. A fine needle biopsy revealed spindle shaped cells consistent with fibromatosis. The histopathology of fibromatosis and the differential diagnosis of jugular foramen masses in children will be described. To our knowledge, this represents the earliest reported case of fibromatosis in the jugular foramen.
