“…86 Displacement or narrowing of the bronchial tree and major vessels and major athelectasis are also common features. 87,88 The routine imaging staging of SCLC should include CT scans of the chest and abdomen, a CT scan or magnetic resonance imaging (MRI) of the brain, and a bone scan. MRI is not a routine diagnostic modality for lung imaging and is usually utilized to resolve ambiguous CT findings.…”

SCLC is the most common BP-NET, while LCNEC is rare, %10% and 1%, respectively, of all lung cancers. Both SCLC and LCNEC progress rapidly, are aggressively metastatic, and exhibit a poor prognosis. The incidence of BP-carcinoids (TC and AC) in the US was 1.57 of 100,000 in 2003 (an unexplained and substantial increase over the last 30 years, %6% per year). No curative treatment except for radical surgery (almost never feasible) exists. The slow-growing TC exhibit a fairly good prognosis (%88%, 5-year survival), whereas AC demonstrate a 5-year survival of %50%, and the highly malignant LCNEC and SCLC 5-year survival of 15% to 57% and <5%, respectively. This review provides a broad overview on BPNETs and focuses on the evolution of the disease, general features, and current diagnostic and therapeutic options.

“…The role of MRI in the evaluation of lung neoplasms is increasing, particularly in the staging of lesions and in the clinical follow-up of the treatment. How-ever, little has been reported in the literature (15) about MRI in the evaluation of NTL, and its role, particularly regarding diagnostic accuracy in the different histological types of NTL, still requires further investigation.…”

OBJETIVO: Descrever os principais achados de imagem em uma série de casos de tumores neuroendócrinos primários do pulmão (TNPs), destacando as alterações na tomografia computadorizada. MATERIAIS E MÉTODOS: Exames de 22 pacientes (12 homens, idade média de 60 anos) avaliados nos últimos cinco anos em nosso serviço, com confirmação histopatológica, foram retrospectivamente revistos por dois médicos radiologistas e os achados foram descritos em consenso, focando as alterações tomográficas. RESULTADOS: Descrevemos 5 carcinoides típicos, 3 carcinoides atípicos, 3 carcinomas neuroendócrinos de grandes células (CNGCs) e 11 cânceres pulmonares de pequenas células (CPPCs). Apenas um carcinoide típico apresentou aspecto característico de nódulo endobrônquico central com atelectasia pulmonar distal, enquanto os demais foram nódulos ou massas pulmonares. Os carcinoides atípicos eram massas pulmonares periféricas e heterogêneas. Um CNGC era massa periférica delimitada e homogênea, enquanto os demais eram mal delimitados e heterogêneos. Os 11 CPPCs eram massas centrais, infiltrativas e heterogêneas, com alterações pleuropulmonares secundárias. Calcificações estavam ausentes nos CNGCs e CPPCs. Metástases foram vistas inicialmente ou no seguimento de todos os CNGCs e CPPCs. CONCLUSÃO: Apesar de alguns aspectos semelhantes nos exames de imagem, os achados radiológicos, quando integrados às informações clínicas, podem constituir critérios importantes na diferenciação dos tipos histológicos de TNPs.

“…lesions of high signal intensity on T2-weighted images and short T1-inversion-recovery images (Fig 26) (50). Although MR imaging does not allow carcinoids to be differentiated from other central neoplasms, it may be helpful in distinguishing these lesions from adjacent normal vascular structures (51).…”

Carcinoids are neuroendocrine neoplasms. Bronchial carcinoids are unusual, malignant primary neoplasms that characteristically involve the central airways and typically exhibit well-defined margins and bronchial-related growth. Bronchial carcinoids include low-grade typical carcinoids and the more aggressive atypical carcinoids. These tumors usually affect patients in the 3rd through 7th decades of life who are often symptomatic with cough, hemoptysis, or obstructive pneumonia. Bronchial carcinoids radiologically manifest as hilar or perihilar masses, with or without associated atelectasis, pneumonia, bronchiectasis, or mucoid impaction. At computed tomography, an anatomic relationship of these tumors to a bronchus is usually seen, and they may show contrast material enhancement or calcification. In rare cases, carcinoids occur in the thymus; when they do, they are aggressive tumors that affect adults who usually present with chest pain, cough, and dyspnea. Thymic carcinoids manifest radiologically as anterior mediastinal masses and may mimic thymomas. Thoracic carcinoids are treated by surgical excision. The prognosis for patients with typical bronchial carcinoids is excellent; patients with atypical bronchial or thymic carcinoids have a worse prognosis.
