Primary pulmonary primitive neuroectodermal tumor: CT and skeletal scintigraphic image features with pathologic...

Area of Science:

• Oncology
• Pulmonary Medicine
• Pathology

Background:

• Primitive neuroectodermal tumors (PNETs) are rare, aggressive neoplasms.
• Primary pulmonary PNETs are exceptionally uncommon, posing diagnostic challenges.

Observation:

• A 28-year-old woman presented with an incidentally discovered right lower lobe lung mass on chest X-ray prior to delivery.
• Imaging revealed a large, heterogeneous mass with calcifications and a small pleural effusion.
• The mass was surgically resected one month postpartum.

Findings:

• Pathology confirmed a primary pulmonary PNET with focal visceral pleural invasion.
• The resected tumor measured approximately 9.2 x 8.4 x 6.3 cm.

Implications:

• This case highlights the importance of considering rare diagnoses in pulmonary masses.
• Understanding PNET presentation and management is crucial for effective treatment strategies.
• Further research into primary pulmonary PNETs may improve diagnostic accuracy and patient outcomes.
