1 Felon: This bacterial infection of the finger pad, caused by the same organisms that cause paronychia, is usually the result of a puncture wound. 2  The wound allows the introduction of bacteria deep into the fingertip pad. 3  Because the fingertip has multiple compartments, the infection is contained in this area.
The interlobular septae are located between secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa.he interlobular septa are incomplete allowing for communication between adjacent secondary pulmonary lobules (canals of Lambert and pores of Kohn).
(A,B) Fine unilateral reticular pattern. (C) Soft tissue mass producing pulmonary artery obstruction. Thickening of the interlobular septa is a common and easily recognized high-resolution computed tomography feature of many diffuse lung diseases. In some cases, it is the predominant radiological finding. This article reviews the spectrum of entities that commonly present with thickening of the interlobular septa as the main radiological feature and establishes a practical approach for the differential diagnosis.
