18FDG Uptake in Sinonasal Inverted Papilloma Detected by Positron Emission Tomography/Computed Tomography
Inverted papilloma (IP) is a benign but locally aggressive sinonasal tumour. Aggressive surgical treatment has thus been traditionally recommended because of the risk of transformation in squamous carcinoma. CT and MRI are used to evaluate bone destruction and soft-tissue extension before surgery but may be ineffective to differentiate an inverted papilloma from squamous cell carcinoma. In rece...
متن کاملTRANSNASAL ENDOSCOPIC APPROACH FOR SINONASAL INVERTED PAPILLOMA
Inverted papillomas of the nose and paranasal sinuses are uncommon neoplasms, characterized by their tendency to occur and by their association with malignancy. In the past decade there has been a trend toward the use of endoscopic surgical techniques in the management of these tumors. This article presents the results of a prospective study of24 patients with inverted papilloma resected by...
متن کاملUptake of 18FDG by a Hepatic Adenoma on Positron Emission Tomography
Fluorodeoxyglucose positron emission tomography ((18)FDG-PET) is currently the best noninvasive test to confirm hepatic metastases when diagnostic uncertainty exists after initial imaging with first-line modalities. However, we report the second case of "false-positive" uptake of (18)FDG on PET scanning from a histopathologically confirmed hepatic adenoma.
متن کاملCOX-(2) overexpression in sinonasal inverted papilloma.
BACKGROUND Inverted papilloma (IP) is a benign, but locally aggressive neoplasm of the nasal cavity and paranasal sinuses. The mainstay of treatment of IP is surgical resection, but high rates of tumor recurrence have been reported. Cyclo-oxygenase-2 (COX-2) has been found to be overexpressed in many tumors and has been used successfully as a therapeutic target. The goal of this study is to hig...
