A 39 years old male patient was admitted with the right of facial abnormalities and gradually protruding in right eye more than 30 years. CT shows high mixed density, clear boundary, and the right eye was crowded to the right. Giant tumor had completely been excised, and the result was fine. The outline figure and function of patients were obviously improved. The pathological examination after resection showed ossifying fibroma.

Foreign bodies in the paranasal sinuses are rare. Foreign bodies in the ethmoid sinus are easily misdiagnosed as tumor. There is no typical display in CT and MRI tests. The described case showed the misdiagnosis of an ethmoid foreign body as tumour on the basis of CT and MRI results. It should be emphasised that the tumour diagnosis should be based on further physical and histopathological examinations and not only on the results of CT and MRI tests.

Female patients, 50 years old, have a recurrent unilateral aggravating headache for 5 years. Without runny nose, sneezing, nasal hemorrhage, smell or vision loss. Prefessional examination: there is a visible hoar neoplasm in the right middle nasal meatus With smooth surface and rich in vascular. The nasopharyngeal MRI shows that there is a occupancy lesion in the right nasal cavity and sinuses, well-demarcated, about 21. 5 mm x 25.5 mm x 37.0 mm. Angiofibroma is the most likely diagnosis. Postoperative pathological section shows that tumor are hypercellular, which contains big nucleus. Cells are spindle or short fusiform shape, there are stripes and nuclear division in some cells. There are vortex structures in partial region. Immunohistochemical examination shows: CD34(++), Ki-67 (< 5%), CD68(-), Des (-), NSE(+), S-100(++), SMA(-), EMA (+). Histopathologic diagnosis: atypical meningioma, some were differentiated to rhabdoid meningioma. The final diagnosis is malignant meningioma in nasal cavity and paranasal sinuses.

A patient diagnosed with myoepithelial carcinoma was recently treated in our department. The neoplasm was huge, located in the left maxillofacial region, blocking both eyes, impeding feeding. About one month before admission, the tumor began to bleed frequently, about 100 ml each time, causing headache, dizziness, fatigue, and cold sweats. CT showed the maximum diameter of the tumor was about 23 cm, with uneven density, and maxillofacial bone destruction. MRI revealed internal bleeding and necrosis inside the tumor. After admission, blood routine test showed erythrocyte count 3.64 x 10(12)/L(↓), hemoglobin 106 g/L(↓), hematocrit 0.320 (↓), serum iron 6.2 μmol/L(↓). After surgery, the patient recovered smoothly.

OBJECTIVE: To investigate the clinical characteristics, therapeutic efficacy and misdiagnosis status of sphenoid sinus malignant tumor in order to improve the diagnosis rate. METHOD: Analysing and summarizing 18 patients with sphenoid sinus malignant tumor in our department from 1996 to 2005. RESULT: The metastatic nasopharyngeal carcinoma is the most of sphenoid sinus malignant tumor,the second is chordocarcinoma and non-Hodgkin lymphoma, its clinical manifestation was headache (78%), sight alteration (50%), cranial nerve palsy (39%), nose bleed (11%); the clinical diagnosis rate was 56%. CONCLUSION The nasal endoscopy is the convention examination for these patients with sphenoid sinus malignant tumor whose imageology diagnosis is of limitation.

OBJECTIVE: To investigate the clinical features and treatment options of ossifying fibroma of paranasal sinuses. METHOD: A retrospective evaluation of twenty-three patients with ossifying fibroma of paranasal sinuses was presented. The choice of surgical operations on ossifying fibroma of paranasal sinuses was mainly decided by the location and area of ossifying fibroma. Radical operations were performed in twenty-one patients, ten of them through a lateral rhinotomy approach, eight through nasal endoscopic approach, four through Caldwell-Luc approach, one through coronal approach. RESULT: Two patients were performed partial resection by nasal endoscopic surgery. Diagnoses of all cases were confirmed by pathology. All patients outcomes were successful, no serious complication from the surgical technique occurred. Twenty cases were followed-up for six months to nineteen years. Two patients recurred. CONCLUSION Earlier diagnosis, CT scan, proper surgery, and radical resection are the keys to the treatment of ossifying fibroma of paranasal sinuses.

Teratomas represent 0.5% of all intracranial tumors. These benign tumors contain tissue representative of the three germinal layers. Most teratomas are midline tumors located predominantly in the sellar and pineal regions. The presence of a teratoma in the cavernous sinus is very rare. Congenital teratomas are also rare, especially those of a cystic nature. To our knowledge, this would be the first case report of a congenital, rapidly growing cystic teratoma within the cavernous sinus. A three-month-old boy presented with a past medical history of easy irritability and poor oral intake. A magnetic resonance image (MRI) scan of the head disclosed a large expanding cystic tumor filling the right cavernous sinus and extending into the pterygopalatine fossa through the foramen rotundum. These scans also demonstrated a small area of mixed signal intensity, the result of the different tissue types conforming to the tumor. Heterogeneous enhancement was seen after the infusion of contrast medium. However, this was a cystic tumor with a large cystic portion. Thus, a presumptive diagnosis of cystic glioma was made. With the use of a right frontotemporal approach, extradural dissection of the tumor was performed. The lesion entirely occupied the cavernous sinus, medially displacing the Gasserian ganglion and trigeminal branches (predominantly V1 and V2). The lesion was composed of different tissues, including fat, muscle and mature, brain-like tissue. The tumor was completely removed, and the pathological report confirmed the diagnosis of a mature teratoma. There was no evidence of recurrence. Despite the location of the lesion in the cavernous sinus, total removal can be achieved with the use of standard microsurgical techniques.
