Foreign body (FB) aspiration occurs less frequently in adults than in children. Among the complications related to FB aspiration, pneumothorax is rarely reported in adults. Although the majority of FB aspiration cases can be diagnosed easily and accurately by using radiographs and bronchoscopy, some patients are misdiagnosed with endobronchial tumors. We describe a case of airway FB that mimicked an endobronchial tumor presenting with pneumothorax in an adult. A 77-year-old man was referred to our hospital due to pneumothorax and atelectasis of the right upper lobe caused by an endobronchial nodule. A chest tube was immediately inserted to decompress the pneumothorax. Chest computed tomography with contrast revealed an endobronchial nodule that was seen as contrast-enhanced. Flexible bronchoscopy was performed to biopsy the nodule. The bronchoscopy showed a yellow spherical nodule in the right upper lobar bronchus. Rat tooth forceps were used, because the lesion was too slippery to grasp with ellipsoid cup biopsy forceps. The whole nodule was extracted and was confirmed to be a FB, which was determined to be a green pea vegetable. After the procedure, the chest tube was removed, and the patient was discharged without any complications. This case highlights the importance of suspecting a FB as a cause of pneumothorax and presents the possibility of misdiagnosing an aspirated FB as an endobronchial tumor and selecting the appropriate instrument for removing an endobronchial FB.

Pericardial masses include cysts, pericardial tumours, and pericardial haematomas. Pericardial cysts are benign lesions commonly located in the right cardiophrenic angle that remain typically asymptomatic and are incidentally found in chest X-ray or chest computed tomography but might cause pressure symptoms or become infected, thus requiring surgical management. Hydatid cysts due to echinococcosis are the most common acquired pericardial cysts, characterized by wall calcification, and indicate surgery.

<b><i>Background:</i></b> Little is known about the damage to the respiratory system in asymptomatic patients with coronavirus disease (COVID-19). <b><i>Objective:</i></b> Herein, we evaluate the findings of chest computed tomography (CT) and radiography in patients with COVID-19 who were asymptomatic. <b><i>Methods:</i></b> We retrospectively investigated patients with a confirmed diagnosis of COVID-19 but who did not show any symptoms. Among the 139 patients with COVID-19 who were hospitalized in Yeungnam University Hopistal in Daegu, South Korea, 10 (7.2%) were asymptomatic. Their chest CT and radiographic findings were analyzed. <b><i>Results:</i></b> In the results, all patients (100%) had ground-glass opacity (GGO) on chest CT. Further, the GGO lesions were predominantly distributed peripherally and posteriorly in all patients. In 9 (90%) patients, the GGO lesions were combined with reticular opacity. Air bronchogram due to bronchiolectasis surrounded by GGO was observed in 8 patients (80%). Additionally, the lung lesions were dominant on the right side in all patients. <b><i>Conclusions:</i></b> In conclusion, considering our results that the lung is affected in asymptomatic patients, it will be necessary to extend the indications of COVID-19 testing for effective management of COVID-19 during the pandemic.

Foreign body aspiration (FBA) is a common incidence in young children. Leeches are rarely reported as FBA at any age. This study describes a 15-year-old female who presented with hemoptysis, hematemesis, coughs, melena, and anemia seven months prior to admission. Chest X-ray showed a round hyperdensity in the right lower lobe. A chest computed tomography (CT) demonstrated an area of consolidation and surrounding ground glass opacities in the right lower lobe. Hematological investigations revealed anemia. Finally, bronchoscopy was performed and a 5 cm leech was found within the rightB7-8bronchus and removed by forceps and a Dormia basket.

Pulmonary carcinoids originate from neuroendocrine cells of the lung and comprise 0.5%–5% of all lung malignancies. Endobronchial carcinoids are rare, low-grade malignant tumors that occasionally coexist with other infectious diseases, including tuberculosis and nontuberculous mycobacterial infection. We treated a 63-year-old woman who presented with a right middle lobe obstruction. A chest computed tomography scan demonstrated a mass-like lesion in the right middle lobe with mediastinal lymphadenopathy. She underwent an exploratory operation after 2 weeks of antibiotic treatment. The pathology revealed a right middle lobe bronchial carcinoid tumor and aspergillosis. Chest computed tomography scans have revealed no recurrence of the carcinoid or aspergillosis during the 5-year follow-up.

A 73-year-old woman was referred to the pulmonology department for abnormal findings on chest computed tomography. She had undergone a laparoscopic staging operation including a hysterectomy, bilateral salpingo-oophorectomy, bilateral pelvic node and para-aortic node dissection, and concurrent chemo-radiation therapy for endometrial serous carcinoma stage IIIc cancer 15 months earlier. A follow-up chest computed tomography after the chemotherapy showed that the right lower lobe bronchus was obstructed, and it was necessary to differentiate a primary lung malignancy from a metastasis and secretion. A positron emission tomography revealed an intense hypermetabolic nodule in the right lower lobe bronchus and diffuse hypometabolism of the right lower lobe lung. Bronchoscopy revealed a tumor mass obstructing the right lower lobe bronchus, and an endobronchial biopsy confirmed a metastatic serous carcinoma from the endometrium. We described an endobronchial metastasis from an endometrial carcinoma with various diagnostic images and histology. To the best of our knowledge, this is the first report of an endobronchial metastasis from an endometrial carcinoma in Korea.

Összefoglaló. Bevezetés: Congenitalis coronariaanomáliának tekintik azokat a coronariamorfológiai rendellenességeket, melyek 1%-nál kisebb gyakorisággal fordulnak elő. Többségük nem jár tünettel, olykor azonban okozhatnak mellkasi fájdalmat, eszméletvesztést, és hirtelen halálhoz is vezethetnek. A coronariaanomáliák gyakoriságáról Magyarországon eddig csak invazív koronarográfiás adatok alapján jelent meg közlemény. Célkitűzés: Jelen vizsgálatunkban a coronariák eredési rendellenességeinek gyakoriságát mértük fel intézetünk coronaria-komputertomográfiás angiográfián átesett betegeinél. Módszer: A coronaria-komputertomográfiás vizsgálatra került betegek felvételeinek értékelésekor rögzítettük a coronariaanomália jelenlétét. A vizsgálat indikációja általában mellkasi fájdalom volt. 128 szeletes berendezést használtunk, a vizsgálatok során részben retrospektív, részben prospektív EKG-kapuzást alkalmaztunk. Eredmények: 1751 beteg komputertomográfiás angiográfiás felvételeit elemeztük. A betegek között a férfiak aránya 38,4%, a vizsgálatra kerülők életkorának átlaga pedig 58,07 ± 11,07 év volt. Eredési anomáliát 1,83%-ban találtunk, ezen belül a leggyakoribb volt a körbefutó ág (ramus circumflexus) és az elülső leszálló ág különálló eredése a bal Valsalva-sinusból (1%). A további rendellenességek a következők voltak: a jobb coronaria eredése magasan az aortából (0,34%), ramus circumflexus a jobb sinusból vagy a jobb coronariából (0,34%), jobb coronaria a bal Valsalva-sinusból (0,057%), elülső leszálló ág részben a bal Valsalva-sinusból a circumflexustól külön, részben a jobb coronariából (kettős elülső leszálló ág, 0,057%). Következtetés: Mindössze 0,057%-ban fordult elő potenciálisan tünetet okozó coronariaeredési rendellenesség (a bal sinusból eredő jobb coronaria). A komputertomográfiás angiográfia segítségével a coronariaeredés helye pontosan megállapítható, tisztázható az ér lefutása és ennek során viszonya a környező struktúrákhoz. Orv Hetil. 2020; 161(47): 1995–1999. Summary. Introduction: Congenital coronary artery anomaly is defined as a coronary morphology which occurs in less than 1% of the cases. Usually these anomalies do not result in symptoms but sometimes they can cause chest pain, syncope and sudden death. In Hungary, the prevalence of these abnormalities was published only from data of invasive coronary angiography. Objective: In this study, we evaluated the prevalence of the anomalies of coronary origin in the patients of our institution undergoing coronary computed tomography. Method: While reading the computed tomography angiograms of our patients, we registered the presence of coronary anomalies. In most of the cases, the indication of the coronary computed tomography was chest pain. A scanner with 128 detectors was used, scans were performed partly with prospective, partly with retrospective ECG gating. Results: We assessed 1751 patients. The ratio of males was 38.4%, while the average age of patients 58.07 ± 11.07 years. Anomaly of coronary origin was present in 1.83% of our patients, with the separate origin of left anterior descending and left circumflex artery being the most frequent (1%) among them. Other anomalies were as follows: high take-off of the right coronary artery from the ascending aorta (0.34%), left circumflex arising from the right sinus of Valsalva or from the right coronary (0.34%), right coronary artery from the left sinus of Valsalva (0.057%), left anterior descending arising partly from the left sinus of Valsalva, apart from the left circumflex, partly from the right coronary (dual left anterior descending artery, 0.057%). Conclusion: The prevalence of potentially symptomatic coronary anomalies was only 0.057% in our series (right coronary from the left sinus of Valsalva). The computed tomography angiography can precisely define the origin of the coronary artery, depict its run-off and its relationship to the neighbouring structures.

Background: The middle ear cavity is ventilated through the aditus ad antrum. Aditus blockage contributes to the pathology of otitis media. Objective: To determine the normal values of the aditus ad antrum diameter on computed tomography and to investigate its relationship with chronic otitis media and related pathologies (tympanosclerosis and myringosclerosis). Methods: The temporal CT images of 162 individuals were evaluated retrospectively. In the axial sections, the inner diameter of the aditus was measured at the narrowest point at the cortex. The differences in diameter were compared between diseased and healthy ears. Results: In healthy individuals, the diameter was narrower in women. There was no difference between the right and left ears in healthy subjects. No correlation was found between age and diameter. In male patients with myringosclerosis, the diameter was slightly narrower on both sides but more marked on the left. In female patients with myringosclerosis, the diameter in both ears was slightly narrower. In cases of otitis media and tympanosclerosis, the diameter was less than that of healthy individuals, despite the lack of statistically significant result in all cases. Conclusion: The aditus ad antrum was narrower in diseased ears, indicating that a blocked aditus may contribute to the development of otitis media, as well as mucosal diseases.
