Cavities are a very rare feature of emboli/infarcts and their presence in a case of suspected pulmonary infarct
indicates septic embolization .
immitis dirofilariasis is not a cardiac infection, but a vascular infection in animals and man, and the pathognomonic "coin lesion" in HPD is an organized granuloma and not a pulmonary infarct
Once haemodynamic stability had been achieved with ECMO, a repeat CTPA was performed, showing bilateral large pulmonary emboli involving the left and right pulmonary arteries and a pulmonary infarct
of the left lower lobe (Figure 3).
With no treatment, children face an ever-looming risk of acute pain crises, stroke, or pulmonary infarct
. Without treatment, children with sickle cell disease cannot play competitive sports.
The contrast-enhanced CT evaluation of a pulmonary mass after Swan-Ganz catheter placement helps differentiate IPAP from pulmonary infarct
and limited parenchymal hemorrhages of other origins.
Additionally, nearly one quarter of the cases (13 of 55) were also found to have PTE, often adjacent to areas of pulmonary infarct
. In the Brazilian paper by Mauad et al, all 21 patients were found to have renal acute tubular necrosis with four demonstrating renal deposition of myoglobin pigment.

Causes of false-positive diagnoses in lung FNA include granulomatous inflammation, thermal/irradiation/chemotherapy effects, lung abscess, pulmonary infarct
, diffuse alveolar damage, organizing pneumonia, and pulmonary fibrosis.
: an unusual manifestation of fibrosing mediastinitis.
Microscopic examination of the nodule revealed an oval-shaped, well-circumscribed pulmonary infarct
(Figure 1, A) containing several sections of thrombosed pulmonary artery best illustrated by Movat stain (Figure 1, C).
 In the context of RSIE, inclusion of septic pulmonary infarcts
as a minor criterion in the modified Dukes criteria may therefore be inappropriate and these should rather form part of the major criteria.
