Diagnosis of Primary Intestinal-Type Adenocarcinoma in the Nasal Cavity by 18F-FDG PET/CT

FDG PET/CT in Isolated Nasal Cavity Metastasis From Squamous Cell Lung Cancer

ABSTRACT

Nasal cavity metastasis is rare. We present FDG PET/CT findings in a case with isolated nasal cavity metastasis from squamous cell lung cancer. The nasal cavity tumor invaded the nasal septum and hard palate and showed intense inhomogeneous activity, mimicking a primary malignancy. Knowledge of the atypical manifestations of metastatic lung cancer will be helpful for correct diagnosis.

Increased 68Ga-FAPI Activity in Chondrosarcoma of Nasal Cavity

ABSTRACT

Chondrosarcoma is a rare entity tumor, which mainly appears in long bones and pelvic bones, but rarely in nasal cavity. Herein, we report the 68Ga-FAPI PET/CT findings in a 54-year-old man with chondrosarcoma of nasal cavity.

Diagnosis of Multiple Primary Intestinal-Type Adenocarcinoma in the Lung by 18F-FDG PET/CT

A 74-year-old man with multiple soft tissue lesions in the lung, which were suspected to be metastatic neoplasms, underwent F-FDG PET/CT scan to detect primary malignancy. The images demonstrated that the lung and 2 retroperitoneal lymph nodes were the only affected organ or tissues with suspected primary lung neoplasms. Multiple intestinal-type adenocarcinoma was eventually diagnosed by CT-guided transthoracic needle aspiration biopsy.
