Tumors of the parapharyngeal space
, in Myers EN, Suen JY (eds): Cancer of the Head and Neck.
Computed tomography, magnetic resonance imaging, and magnetic resonance angiography scans revealed a nonvascular mass positioned in the prestyloid parapharyngeal space
The parapharyngeal space
is located lateral to the pharynx.
Imaging revealed the presence of two large neurofibromas--a 60 x 50 x 35-mm tumor in the left parapharyngeal space
and an intradural tumor measuring 25 mm in diameter.
Giant deep lobe parotid gland pleomorphic adenoma involving the parapharyngeal space
Computed tomography identified a mass with radiologic features suggestive of a malignancy of the maxillary sinus and orbit; the mass extended into the infratemporal fossa, parapharyngeal space
, anterior antral wall, and surrounding soft tissue.
tumors account for less than 1% of all head and neck neoplasms.
Hemangiopericytomas of the head and neck are rarely found in the parapharyngeal space
In 1999, Guinto et al described their use of the zygomatic-transmandibular approach in the treatment of 10 patients with massive tumors that were localized in the infratemporal fossa and parapharyngeal space
Necrotizing fasciitis of the parapharyngeal space
with carotid artery occlusion and acute hemiplegia.
Magnetic resonance imaging (MRI) demonstrated a well-marginated mass in the left parapharyngeal space
The presence of a connection between the parapharyngeal space
and the oral cavity may lead to a deep neck infection, carotid injury/ blowout from salivary enzymes, or subcutaneous/intrathoracic emphysema, which can lead to infections or respiratory distress.
On physical examination, an enlarged left-sided neck mass was observed, with erythema extending into the parapharyngeal space
On head and neck computed tomographic imaging, a left parotid mass with internal low densities and many enlarged lymph nodes in left parotid, carotid, and parapharyngeal spaces
were noted, suggesting WT associated with tuberculous or suppurative lymphadenitis (Figure 2).
Deep neck infections include those involving the retropharyngeal and parapharyngeal spaces
