“…However, there is a lack of knowledge concerning the features of atypical or rare types of lung cancer, thus, these types of cancer are subject to misdiagnosis, missed diagnosis and treatment delay. Among these types of cancer, solitary thin-walled cavity lung cancer is particularly rare (8–11). Doctors often lack the understanding of this type of cancer and, therefore, misdiagnose it.…”

The aim of the present study was to analyze and improve the understanding of computed tomography (CT) and positron emission tomography (PET)/CT imaging and the pathological features of solitary thin-walled cavity lung cancer. A total of 16 patients with pathologically confirmed solitary thin-walled cavity lung cancer were included in the present study. All of the patients received CT scans. Among these, two patients underwent an additional PET/CT examination. The CT and PET/CT images were analyzed and a cross-check analysis of the pathological results was conducted. In total, 16 cases of lesions demonstrated thin-walled cavities on the CT images. Among these cases, three presented with an uneven thickening of the cavity walls, 10 cases exhibited wall nodules and three cases presented with compartments in the cavity. The standard uptake value (SUV) of the cavity wall increased in two patients who underwent PET/CT examinations. The 16 cases of lesions were pathologically confirmed as adenocarcinomas. Light microscopy revealed that the tumor cells, which were observed in 12 cases of lesions, had diffused along the inner cavity wall and the tumor cells of four cases had invaded the bronchial wall. Images of the chest that demonstrated a single thin-walled cavity accompanied by uneven thickening of the cavity wall or wall nodules, in addition to an increase in the SUV and compartments in the cavity, indicated potential lung cancer. Valves formed as a result of bronchial wall damage may have led to the cavity.

“…However, atypical lung cancer presenting as solitary thin-walled cavity is encountered on occasion [3][4][5][6]. It is usually misleading, giving a false sense of security, and delaying invasive examination and operation.…”

“…[ 21 ] Percutaneous needle washing and aspiration of cavitary lesions for cytological examination may be useful for diagnosis. [ 22 ] Radiological features including single thin-walled cavity accompanied by uneven thickening of the cavity wall or wall nodules, increased SUV by FDG-PET, and compartments in the cavity on CT images probably indicate lung cancer. [ 10 ] However, FDG-PET is useful for workup of lesions with a solid component >8 mm.…”

Rationale:Asymptomatic, isolated, and thin-walled cystic lung cancer with extensive extrapulmonary metastasis is rare, and the risk of pulmonary cyst developing into lung cancer is poorly understood. The efficacy of apatinib for end-stage pulmonary adenosquamous carcinoma has not been clarified yet.Patient concerns:We herein report a rare case of primary lung cancer that appeared as an isolated thin-walled cystic lesion on computed tomography (CT) image, who was initially misdiagnosed as having pulmonary cyst empirically.Diagnoses:Fluorine-18-fluorodeoxyglucose-positron emission tomography and CT-guided liver biopsy of the patient revealed extra-pulmonary metastasis of lung cancer.Interventions:Eight cycles of cisplatin-based chemotherapy were administered, followed by oral apatinib for 6 months. Thereafter, best supportive care was given for this patient.Outcomes:The pulmonary cystic lesion indicated stable disease through the therapy, but the hepatic tumors were progressed gradually after anticancer treatment. The patient died 16 months after the correct diagnosis.Lessons:Solitary thin-walled cystic lung cancer should be kept in mind during the differential diagnosis of pulmonary cavitary lesions. Chest CT alone is insufficient for surveillance of these cystic diseases. Timely biopsy and resection are essential to avoid delayed management. Besides, apatinib may play a role in the treatment of end-stage pulmonary adenosquamous carcinoma.

Percutaneous Needle Washing for the Diagnosis of Pulmonary Thin-walled Cavitary Lesions Filled with Air

Abstract: Objective It is difficult to obtain sufficient material from pulmonary thin-walled cavitary lesions filled with air by conventional percutaneous aspiration biopsy in order to make a diagnosis. In these cases, we performed percutaneous needle washing (PNW)
