Isolated Sphenoid Sinus Disease

The sphenoid sinus has often been referred to as the neglected sinus because of its isolated position and difficult accessibility. Disease restricted to the sphenoid sinus is rare and often manifests with nonspecific or subtle signs and symptoms. Typically, patients are referred to the otolaryngologist because of a finding of isolated sinus opacification on CT scans ordered by the patient’s primary care physician or neurologist to evaluate vague symptoms such as headache.

Classification Isolated sphenoid sinus disease can be broadly divided Inflammatory Neoplastic Miscellaneous categories

Inflammatory lesions Sinusitis Acute Chronic Fungal infections Invasive: Mucormycoses, disseminated Aspergillosis Noninvasive: Mycetoma, Aspergilloma Mucoceles Pyoceles

Neoplastic lesions Benign Malignant Intrinsic: 1. Inverting papillomas 2. Myofibroma 3. Schwannoma 4. Osteochondroma 5. Fibro-osseous disorders (fibrous dysplasia, ossifying fibroma) Extrinsic: 1. Meningioma 2. Paraganglioma 3. Pituitary macroadenomas Primary: 1. Squamous cell carcinoma 2. Adenocarcinoma 3. Adenoid cystic carcinoma 4. Mucoepidermoid carcinoma 5. Undifferentiated carcinoma 6. Transitional cell carcinoma Metastatic: 1. Renal cell carcinoma 2. Thyroid carcinoma 3. Prostate adenocarcinoma 4. Breast carcinoma 5. Lung carcinoma 6. Melanoma 7. Multiple myeloma and lymphoma

Miscellaneous Cerebrospinal leaks Traumatic Spontaneous Encephaloceles

Clinical signs and symptoms The most common symptom of sphenoid sinus disease is headache Visual disturbance is the second most frequently reported symptom Nasal obstruction Smell and taste Cranial nerve palsies Dizziness

Evaluation CT Scan: Air-fluid level Acute & Chronic sinusitis Polyp Aneurism Thining & Expansion Mucocel tumor Sclerosis Fungal Fibroossous Bone erosion Malignant Tumor

Chordomas Relatively rare tumors deriving from rests of embryonal notochord tissue located in the skull base, spine, and sacrococcygeal regions. Skull base chordomas are typically located in the midline, in the clival and basisphenoid regions

Symptoms Slow-growing tumors; therefore, most patients will relate a fairly long history of symptoms on initial presentation. Symptoms in a given patient will depend on the exact location of the tumor. Most commonly, the patient will report headaches and visual changes Diplopia secondary to cranial nerve (CN)VI paresis, Facial numbness, facial droop, Dysphagia, Hoarseness CN XII paresis

Evaluation CT Scan MRI Reveal destruction of bone in a lytic pattern T1: Isointense or hypointense lesion T2: bright signal that may appear heterogeneous. Gd: Enhancement is typically moderate to high

Management Current and historical management of skull base chordomas has involved : Surgical excision Radiation therapy Both
