Perifissural lung nodules

Perifissural lung nodules (PFNs) are a type of intrapulmonary nodules. They commonly represent intrapulmonary lymph nodes 1. There is some overlap with the term perilymphatic pulmonary nodules since the latter can be perifissural.

Radiographic features

CT chest

PFNs are typically seen as well-circumscribed, smoothly marginated nodules in contact with or closely related to a pulmonary fissure. Most show a triangular, oval, round, rectangular, or dumbbell shape. They may often show a septal attachment to the pleural surface 3.

Treatment prognosis

If they have typical morphology they are favoured to be benign despite some nodules having tendency to grow over serial scans 2.
