It can be many tings : fibrosis calcified nodule (to the local old lesion - tuberculosis, dust intake to the workplace ), cancer, active tuberculosis, autoimmune disease, and more.
The differentiation can be made on radiography, MRI, microscopic examination from biopsy fragment.
A pulmonary embolism is also characterized as central or peripheral, depending on the location or the arterial branch involved. Central vascular zones include the main pulmonary artery, the left and right main pulmonary arteries, the anterior trunk, the right and left interlobar arteries, the left upper lobe trunk, the right middle lobe artery, and the right and left lower lobe arteries.

From the Femoral vein, you would go to the inferior vena cava, which then leads to the right atrium of the heart. From there, you'd go tothe right AV valve to the right ventricle and then to the pulmonary SL valve. Then, you'd go to the pulmonary artery and then the lungs. Once in the lungs, go to the lower lobe of the right lung. There are three lobes within the rght lung, unlike the left lung, wich has two. The three lobes are the Superior lobe, at the top, the Middle lobe, in the middle, and lastly, the Inferior lobe at the bottom
The pulmonary veins running from the upper lobes seem more prominent than those running from the lower lobes.
An upper lobe nodule is a small, abnormal growth or mass located in the upper lobe of the lung, often detected through imaging studies like chest X-rays or CT scans. These nodules can vary in size and may represent a range of conditions, from benign (like infections or scars) to malignant (such as lung cancer). The significance of an upper lobe nodule typically depends on factors like its size, appearance, and the patient's risk factors for lung disease. Further evaluation, including follow-up imaging or biopsy, may be necessary to determine the nature of the nodule.

lobectomy is the removal of a lobe, or section, of the lung
An FDG avid pulmonary nodule with a maximum standardized uptake value (SUV) of 3.2 indicates that the nodule has increased metabolic activity, as measured by positron emission tomography (PET) using fluorodeoxyglucose (FDG). An SUV of 3.2 suggests that the nodule is likely to be malignant, although not definitively, as benign lesions can also exhibit increased uptake. Further evaluation, such as biopsy or imaging follow-up, is usually recommended to determine the nature of the nodule.
The ear has a lower part called a lobe.
It is a mistake. The isthmus of the thyroid gland is a thin bridge across the trachea, linking the right and left lobes. It occasionally also gives rise to the pyramidal lobe, a normal variant of thyroid anatomy. The adjectival form of isthmus is isthmic, so a nodule in the thyroid isthmus is an isthmic nodule, not an isthmal nodule.
