Introduction

A 17mm pulmonary nodule with spiculated margins may be caused by fibrous tissue proliferation, tuberculoma, malignant tumors, or other conditions. Treatment should be tailored according to the underlying cause. Additionally, if spiculated margins are observed in the lung, it is recommended to perform a percutaneous lung biopsy for pathological examination, and actively undergo surgical intervention in cooperation with the physician.

A 17mm lung nodule with spiculated margins may be caused by fibrous tissue hyperplasia, tuberculoma, or malignant tumors. Treatment should be based on the underlying cause.

1. Fibrous Tissue Hyperplasia

Fibrous tissue hyperplasia in the lungs is usually benign and may present with spiculated margins. If the nodule is small—less than 5 mm—regular follow-up imaging is recommended. For nodules larger than 5 mm, surgical removal is advised, such as thoracoscopic minimally invasive resection or lobectomy.

2. Tuberculoma

This condition results from tuberculosis infection in the lung and leads to a benign type of pulmonary nodule. Under medical supervision, anti-tuberculosis medications such as rifampicin capsules or ethambutol hydrochloride tablets may be prescribed.

3. Malignant Tumor

Malignant lung tumors can present with spiculated margins, along with other signs such as air bubble sign (vacuole sign) and perinodular vascular convergence. Prompt surgical intervention under medical guidance is recommended, including procedures like lobectomy and lymph node dissection. Chemotherapy may also be necessary to control disease progression.

In addition, if a lung nodule presents with spiculated margins, a percutaneous lung biopsy is recommended to obtain pathological confirmation. Patients should actively cooperate with their physicians and receive timely surgical or other appropriate interventions as directed.

What is the difference between a lung nodule and a tumor?

The core differences between pulmonary nodules and tumors are reflected in aspects such as definition, nature, imaging characteristics, clinical significance, and management principles. If an abnormal lung shadow is detected, it is recommended to seek timely evaluation and examination at a respiratory or thoracic surgery department. A pulmonary nodule is an imaging term referring to a round or nearly round space-occupying lesion in the lung with a diameter ≤3 cm.

What does it mean when the maximum CT value of a pulmonary nodule is 105 HU?

A lung nodule with a maximum CT value of 105 Hounsfield units (Hu) indicates relatively high density, close to calcification or containing substantial dense components. Such nodules are mostly benign, such as old tuberculosis lesions, inflammatory scars, or calcified nodules. However, further evaluation is still needed to rule out rare malignant possibilities. It is recommended to visit a pulmonologist or thoracic surgeon promptly. CT value is a measure of tissue density.

What Chinese herbal medicines should patients with lung nodules take?

In general, patients with pulmonary nodules may use traditional Chinese herbs for regulation under the guidance of a physician. Commonly used herbs include Prunella vulgaris (Xia Ku Cao), Zhe Bei Mu, dandelion, Hedyotis diffusa (Bai Hua She She Cao), and Salvia miltiorrhiza (Dan Shen). In addition, other suitable Chinese herbal medicines may also be combined under medical supervision. During treatment, patients should undergo regular follow-up examinations, maintain a light diet, avoid smoking and alcohol consumption, and minimize irritation to the lungs.

Is Maytenus effective for lung nodules?

Maytenus is a plant, and some traditional practices have mentioned its potential anti-inflammatory and mass-dispersing effects. However, these claims lack sufficient clinical evidence. Currently, there is no authoritative evidence indicating that Maytenus can directly reduce or eliminate pulmonary nodules, and it has not been included in standard treatment guidelines for pulmonary nodules. Its effects on nodules remain largely theoretical.

Will lung nodules grow larger after receiving a COVID-19 vaccine?

If the pulmonary nodule is benign and there are no contraindications such as vaccine allergy or acute infection, vaccination will not stimulate the nodule to grow. COVID-19 vaccines primarily work by stimulating the immune system to produce antibodies; they do not directly affect lung nodules nor alter their nature or growth trend. Standard vaccination is considered safe.

Which is more serious: kidney cysts or lung nodules?

The severity of renal cysts and pulmonary nodules cannot be generalized. Overall, malignant pulmonary nodules are more serious. Benign renal cysts and benign pulmonary nodules are both mild conditions, whereas malignant lesions carry a significantly higher risk of progression compared to benign ones. If either condition is detected, or if symptoms such as coughing, hemoptysis, or abdominal pain occur, prompt medical evaluation is recommended to determine the nature of the lesions.

What does "old pulmonary nodule" mean?

Old pulmonary nodules are scar tissues left behind after the healing of previous lung conditions such as infections, inflammation, or tuberculosis. They are mostly benign and asymptomatic, posing no direct threat to health. However, regular imaging follow-ups are still necessary to monitor any changes. If abnormal symptoms such as chest pain, hemoptysis (coughing up blood), or shortness of breath occur, prompt medical evaluation at a hospital's respiratory medicine department is recommended.

Can a person with lung nodules and mild asthma receive the pneumonia vaccine?

Individuals with pulmonary nodules and mild asthma can receive the pneumonia vaccine when their condition is stable. However, if asthma is in an acute exacerbation phase accompanied by symptoms such as wheezing, coughing, or chest tightness, or if the nature of the pulmonary nodule is undetermined or there are signs of infection, vaccination may trigger worsening asthma or impair vaccine response. In such cases, underlying diseases should be treated first, and vaccination should be reconsidered only after the condition has stabilized.
