“…At present, the clinical diagnostic means for primary tracheal tumors include physical examination, blood examination, X-ray, CT, magnetic resonance imaging (MRI), tracheography, and pathological biopsy, which often requires a combination of various results for diagnosis ( 10 , 11 ). The pathological biopsy is the gold standard for determining primary tracheal tumor, which is the most precise examination.…”

Objectiveit aimed to explore the value of multislice helical computed tomography (MSCT) in the diagnosis and surgical treatment of primary tracheal tumors.Methods64 patients with the primary tracheal tumor who were diagnosed in Wuxi Second People’s Hospital from March 2020 to March 2021 were selected as the research objects. MSCT imaging was performed on all patients, and suitable surgical methods. The pathological results were compared with original CT, CT virtual endoscopy (CTVE), and Comparisons were made using CT three-dimensional reconstruction images to evaluate the accuracy of MSCT diagnosis. Parameters such as postoperative complications and survival rates were observed to assess surgical effectiveness and safety.ResultsCompared with original CT images (70%, 72%, 70%), the diagnostic accuracy of VR images (80%, 80%, 80%), MPVR images (85%, 90%, 92%), and CTVE images (100%, 100%, 100%) was remarkably improved (P<0.05). The three-year survival rate of patients with smooth muscle tumors, malignant tumors, salivary gland adenoma, papillary tumors, and inflammatory polyp was markedly lower than that of the one-year survival rate, with a significant difference (P<0.05). The incidence of postoperative complications was 14.1%, with three cases resulting in complication-related deaths.Conclusionthe diagnostic accuracy of MSCT imaging of primary tracheal tumor was high. The diagnostic accuracy of CTVE was higher than that of VR and MPVR. Besides, surgical treatment of primary tracheal tumor had a substantial effect, with no serious postoperative complications.

“…3 Differential diagnoses for tracheal cartilage uptake include polychondritis, 10 polyangiitis with granulomatosis, 11 IgG-4-related disease, 12 tuberculosis, 13 postradiogenic necrosis, 14 or malignancies such as lymphoma, 15,16 lung cancer, 17 and adenoid cystic carcinoma. 18,19 In conclusion, owing to the widespread use of FDG PET/CT in the workup of inflammation of unknown origin, nuclear medicine physicians should be aware of possible FDG uptake patterns and commonly involved organs in the only recently established disease VEXAS syndrome. In the future, FDG PET/CT might also be used for monitoring therapy response in VEXAS syndrome.…”

VEXAS Syndrome With Tracheal Involvement but Absence of Vasculitis in FDG PET/CT

et al. 2023

In early 2022, a 77-year-old man presented with weight loss and recurrent subfebrile temperatures since 6 months. Workup with CT revealed a lung infiltrate. Despite antibiotic treatment, serum inflammation markers remained high. The patient further developed eczematous skin changes, uveitis (sequentially on both eyes), and macrocytic anemia. Finally, an autoinflammatory disease was suspected, and FDG PET/CT was performed. The examination revealed metabolically active foci in several tissues (tracheal cartilage, bone marrow, muscles). Bone marrow aspiration revealed an UBA1 mutation, which is pathognomonic for VEXAS syndrome.

Histological Validation of FDG and PSMA-Targeted PET/CT Imaging in a Rare Tracheal Adenoid Cystic Carcinoma

et al. 2022

Adenoid cystic carcinomas are the second most common entity of tracheal malignancies, which have an overall incidence as low as only 0.2 in 100,000 persons per year. We present the case of a 64-year-old man with a histologically confirmed adenoid cystic carcinoma who sequentially underwent 18 F-FDG PET/CT and 68 Ga-PSMA-11 PET/CTwithin 1 day for staging 3 days before surgical resection of the tumor. Immunohistochemistry revealed PSMA expression of the tumor corroborating the PSMA PET findings.
