Nasal and paranasal sinus carcinoma: are we making progress? A series of 220 patients and a systematic review.

Surgical management of giant intracranial aneurysms

Sixty-two cats with sinonasal disease were evaluated with computed tomography. Findings that may lead to a computed tomographic diagnosis of nasal neoplasia versus rhinitis included osteolysis of the paranasal bones, moderate to severe turbinate destruction, lysis of the nasal septum, the presence of a homogenous space occupying mass, and extension of the disease process into the orbit or facial soft tissues. These findings were not pathognomonic for neoplasia and may be associated with severe rhinitis; therefore, nasal biopsy was recommended. When compared with parallel radiographic studies, computed tomography was not more sensitive than radiographs at detecting the presence of nasal cavity abnormalities in cats with referable clinical signs but was more sensitive at localizing these changes and determining the extent of disease.

Magnetic resonance imaging of sinonasal malignancies.

Background

Endoscopic resection followed by radiotherapy as primary treatment for adenocarcinoma of the sinuses is emerging as an alternative to open resection



Methods

A total of 44 patients primarily treated by an endoscopic approach followed by radiotherapy from 1992 to 2004 seen at our ENT-Department were analyzed for outcome and prognostic factors



Results

Median follow-up was 61 months Median follow-up of the patients alive at the end of the follow-up period was 100 months For the 5-year follow-up, the overall survival, disease-specific survival, and recurrence-free survival were 63% (±7% SE), 82% (±6), and 60% (±8%), respectively The overall survival, disease-specific survival, and recurrence-free survival after 100 months of follow-up were 53% (±8%), 72% (±9%), and 54% (±9%), respectively Four factors significantly influenced the disease-specific survival



Conclusion

This study of a homogeneous cohort of patients with sinonasal adenocarcinoma treated by endoscopic resection and radiotherapy confirms that endoscopic resection is a valid alternative to open resection © 2010 Wiley Periodicals, Inc Head Neck, 2011

The Radiographic Evaluation Of Sinonasal Tumors: An Overview

Objective To present the CT and MR findings of three patients with giant intracranial aneurysms (GIAs), each of which eroded the skull base and had an extracranial mass component. A literature review of GIAs was also performed. Materials and methods In the past year the imaging studies of three patients with these unusual GIAs were collected at our institutions. All three patients had had CT, and one patient had had MR on a 1.5 T GE unit. Results One patient had a 5 cm GIA in the left petrocavernous region, filling the middle cranial fossa and extending into the left sphenoid sinus and the left posterior ethmoid complex. The aneurysm had heterogeneous high attenuation and extensive rim calcification. The second patient had a 5 cm GIA that filled most of the left middle cranial fossa, eroding the floor and lateral wall and extending into the infratemporal fossa and parapharyngeal space. The aneurysm was partially thrombosed and had minimal rim calcification. The third patient had a 4 cm left cavernous GIA that eroded the floor of the middle cranial fossa and extended into the subjacent parapharyngeal space. The lesion was partially thrombosed and had an enhancing lumen. The rim had low signal intensity on MR. None of these patients had a history of trauma. Conclusion Giant intracranial aneurysms can cause significant skull base erosion and extend into the paranasal sinuses, parapharyngeal space, and infratemporal fossa. The CT and MR findings can lead to an accurate diagnosis.

Giant intracranial aneurysms with skull base erosion and extracranial masses: CT and MR findings.

A patient is presented in whom iophendylate (Pantopaque) within the basal cisterns closely resembled the appearance on MRI of thrombosed aneurysms of the middle cerebral arteries. The sometimes subtle differences between the appearances on MRI of Pantopaque and aneurysmal clot are discussed to permit accurate diagnosis without resorting to more invasive diagnostic tests, such as cerebral angiography.
