“…The presence of 18 F-FDG uptake in inflammatory or infective diseases, other than malignant diseases, reduces the specificity of PET/CT ( 8 ). Low 18 F-FDG uptake can be observed in pulmonary hamartomas ( Figure 2 ) ( 9 , 10 ). Ergonul et al ( 9 ) reported 18 F-FDG PET/CT findings of 106 patients with benign lung lesions.…”

“…The SUV max of 19 hamartomas ranged from 0 to 4.5 ( 9 ). Jiang et al ( 10 ) reported the 18 F-FDG PET/CT findings of 14 pulmonary hamartomas with a mean diameter of 1.7±0.8 cm (range, 0.7-3.1 cm), and the mean SUV max of lesions was 1.5±0.6 (range, 0.7-2.6) ( 10 ). Similarly, in the present study, the mean SUV max was 1.65±0.9 (range, 0-3.38).…”

Objectives: This study aimed to evaluate 18 fluorine-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) findings in the differential diagnosis of pulmonary carcinoids and pulmonary hamartomas. Methods: 18 F-FDG PET/CT findings of 34 patients with pulmonary carcinoids (12 atypical, 22 typical) and 32 patients with pulmonary hamartomas were retrospectively evaluated. Both mean diameter and mean maximum standardized uptake value (SUV max ) of hamartomas and carcinoids were compared by Mann-Whitney U and Kruskall-Wallis H tests. Results: The mean longest diameter of atypical carcinoids (3.5±1.7 cm) was higher than that of hamartomas (2.1±1 cm) (p=0.038). No significant difference was found between the mean diameter of typical carcinoids and mean diameter of hamartomas (p=0.128). The mean SUV max of atypical carcinoids (5.97±3.7) and typical carcinoids (4.22±1.7) were higher than those of hamartomas (1.65±0.9) (p=0.002 and p=0.003, respectively). There were collapse/consolidation in 55.8%, bronchiectasis or mucoid impaction in 47%, and air trapping in 14.7% in the peripheral parenchyma of the 34 carcinoids. Collapse/consolidation was detected in a patient with endobronchial hamartoma, and other finding was not found in the parenchyma around hamartomas. Conclusion: The 18 F-FDG uptake of pulmonary carcinoids can vary from minimal to intense. 18 F-FDG uptake can be seen in pulmonary hamartomas. However, the mean SUV max of atypical carcinoids and typical carcinoids were higher compared to hamartomas. Pulmonary carcinoid must be suspected in cases with accompanying bronchial obstruction findings in the periphery of the mass.

“…They concluded that SUVmax value of hamartomas was lower when compared to the other benign conditions including granulomatous lung disease, reactive lymph nodes and interstitial lung disease. Jiang et al 14 analysed PET/CT images of 14 patients with hamartoma and found mean SUV max value as 1.5±0.6 (range between 0.7 and 2.6). In our study, mean SUVmax value of 22 lesions was 1.6±1.0 (range between 0 and 3.2).…”

Background: In this study, we aimed to examine the Computed Tomography (CT) and 18F-fluorodeoxyglucose positron emission tomography/computerized tomography (FDG PET/CT) findings of the pulmonary hamartomas Methods: Histopathologically (after surgical excisional, transbronchial, or transthoracic biopsy) proven pulmonary hamartomas in our institute between 2007 and 2013 were reviewed retrospectively. The CT and PET/CT images were interpreted regarding the lesion diameter, number, location, components and standardized uptake values (SUVmax). Results: A total of 22 (2 endobronchial and 20 parenchymal) hamartomas detected in 21 (11 males and 10 females) patients (an endobronchial and a parenchymal lesion in the same patient). Right lung (63,7%) involvement was common than left lung (36,4%) and upper lobes (50%) involvement than lower lobes (25%). 54,5% of the lesions has smooth margins while 40,9% have lobulated contour and 4.5% had irregular margins. Fat density was observed in 54,5% and calcification in 40.9%. In 18.2% of the lesions neither fat density nor calcification was seen. There was no FDG uptake in 5 lesions. Mean SUVmax value was 1.6±1.0 (range between 0 and 3,2). A SUVmax value > 2.5 was observed in 5 ones Conclusion: Our results were generally consistent with previous reports. But we found a higher female/male ratio and and more common upper lobes involvement of pulmonary hamartoma

“…Hamartomas, including endobronchial ones, incline to stay below-radar in F-18 FDG PET/CT [7,8]. Initial examination and evaluation of all findings, including CT scan and SUVmax value, directed the route towards low activity nodules of the lung: Typical carcinoid, pulmonary adenoma, bronchioloalveolar carcinoma and of course, endobronchial hamartoma [9][10][11].…”

A rare presentation of a rare disease: endobronchial hamartoma with lobar bronchiectasis

Benign lung tumors are very rare, endobronchial hamartomas-one of which-are even more rare. Endobronchial masses tend to represent themselves via obstruction related symptoms and endobronchial hamartomas are not an exception. It is important to diagnose endobronchial masses before they bring untreatable damage to the lung. It is also important to differentiate endobronchial hamartomas from endobronchial malignancies, such as carcinomas, for they also tend to act mildly symptomatic for a long period of time. In our case, the patient was admitted to our clinic with the symptoms of cough and mild hemoptysis. A computed chest tomography showed total bronchiectasis of right upper lobe along with an endobronchial mass in the right upper lobe bronchus. Bronchoscopic biopsy of the mass revealed no diagnosis. We performed a right upper lobectomy and the pathological examination resulted as endobronchial hamartoma. There are numerous cases about endobronchial hamartomas in the literature which represented with countless symptoms and diseases as persistent cough, recurrent pneumonia, local bronchiectasis and so forth. Our case of endobronchial hamartoma representing with total bronchiectasis of a whole lobe of the lung is the first and only case in the English literature to our knowledge.
