1/285. craniopharyngioma invading the nasal and paranasal spaces, and presenting as nasal obstruction.

    A case of craniopharyngioma invading the nasal and paranasal sinuses and presenting as nasal obstruction is reported. Imaging showed a destructive mass of the skull base with involvement of the nose and paranasal sinuses. In the excised mass mitoses were frequent and the proliferation index was high. Invasion of the nasopharynx and presentation as a nasopharyngeal mass is uncommon for a craniopharyngioma. ( info)

2/285. Chondroid hamartoma presenting as a neonatal nasal mass.

    We present a case of a 3-month-old female with a right nasal mass. Upon evaluation with computed tomography, magnetic resonance imaging and angiography, a large right intranasal mass extending through the cribiform plate, displacing the dura, was noted. The patient underwent a combined midfacial degloving and bifrontal craniotomy for complete resection of the tumor mass. Pathologic evaluation demonstrated a mesenchymal tumor with spindle and stellate cells from which islands of immature cartilage emerged. The spectrum of histologic features closely resembled a mesenchymal chondroid hamartoma typically located in the chest wall. It is the first reported case of a chondroid hamartoma of the head and neck in the literature to date. We examine the characteristics and treatment of this unusual tumor. ( info)

3/285. Polyvinylsiloxane dental bite registration material used to splint a composite graft of the nasal rim.

    We describe the construction of a nostril splint made from heavy body silicone-based dental impression material. This bio-compatible material supported a large chondrocutaneous auricular graft during early healing. The splint immobilized and maintained the shape of the alar rim and was further used nightly during the expected period of wound contraction. ( info)

4/285. Single central maxillary incisor with nasal pyriform aperture stenosis--CT diagnosis prior to tooth eruption.

    Two children with nasal pyriform aperture stenosis had the diagnosis of single central maxillary incisor made with CT scanning prior to tooth eruption and the clinical appreciation of this finding. The surgical and clinical implications of this diagnosis will be presented. ( info)

5/285. Primary amyloidosis presenting as a nasopharyngeal mass.

    Amyloid is defined as a pathologic proteinaceous substance which, when deposited between the cells of tissues and organs, leads to various clinical conditions. immunohistochemistry has allowed for better classification and understanding of the pathophysiology of amyloidosis. In the upper aerodigestive tract, amyloidosis is a rare condition occurring most frequently in the larynx. We present the case of a 42-year-old woman with complete nasal obstruction due to primary nasopharyngeal amyloidosis. This represents the first reported case of primary nasopharyngeal amyloidosis containing both the lambda and kappa immunoglobulin light chains. The clinical and radiologic findings, as well as the management of primary amyloidosis of the upper aerodigestive tract, will be discussed. A review of the literature pertaining to nasal and nasopharyngeal amyloidosis will be presented. ( info)

6/285. Aplasia of right internal carotid artery and hypopituitarism.

    BACKGROUND: The pathogenesis of congenital hypopituitarism is unknown in many cases. OBJECTIVE: We report a case of congenital pan-anterior hypopituitarism in association with a complex vascular abnormality involving the central nervous system, nasal pyriform aperture stenosis, and a single central maxillary incisor. MATERIALS AND methods: MRI and MRA were used to define this patient's complex vascular anomaly. RESULTS: The vascular abnormality consists of absence of the right common carotid artery, the right internal carotid artery, the A1 segment of the right anterior cerebral artery, the anterior communicating artery, and partial absence of the M1 segment of the right middle cerebral artery. CONCLUSION: This unusual vascular anomaly may contribute to the pathogenesis of some cases of congenital hypopituitarism and related midline abnormalities, or may result from a common defect that causes pituitary insufficiency.

7/285. Concha bullosa pyocele--undiagnosed for 3 years.

    We report a rare case of post-traumatic concha bullosa pyocele in a diabetic teenager that has gone undiagnosed for 3 years. The clinical findings, radiological features and management are discussed. The literature is reviewed. ( info)

8/285. Acquired immune deficiency syndrome (AIDS) presenting as a nasal septal perforation.

    patients infected with the Human Immunodeficiency Virus (hiv) and those with AIDS may present with many head and neck manifestations. We report a case of an undiagnosed hiv positive male who presented with symptoms due to a nasal septal perforation, and rapidly developed AIDS. The histopathology of the perforation margins revealed active chronic inflammation with no evidence of neoplasia or granuloma. No viral or fungal infection was demonstrable on immunological testing and fungal stain. This is the first reported case of a patient developing AIDS presenting with a nasal septal perforation.

9/285. CT of intranasal pleomorphic adenoma.

    Intranasal pleomorphic adenoma is rare. We report the CT features this tumor in a 41-year-old woman who presented to us with right nasal obstruction and a 2-day history of epistaxis. ( info)

10/285. Suboccipital meningocele presenting as a huge retropharyngeal mass in a patient with neurofibromatosis Type 1. Case report.

    The authors report an extremely rare case of neurofibromatosis Type 1 (NF1) with a suboccipital meningocele presenting as a huge retropharyngeal mass. A 73-year-old woman with typical cutaneous manifestations of NF1 presented with nasal obstruction and dysphagia due to a retropharyngeal mass. magnetic resonance imaging revealed a huge mass lesion extending from the right occipital bone defect to the retropharynx through the right paravertebral region. Computerized tomography scanning after intrathecal administration of contrast material confirmed that the mass was a meningocele protruding through a right occipital bone defect. The authors attempted to ligate this meningocele, most of which was excised via a suboccipital approach, but a second transcervical operation was required. Finally, the meningocele resolved and the patient was discharged without symptoms. ( info)
