Major aortopulmonary collateral arteries (MAPCAs) develop early in embryonic life but regress as the normal pulmonary arteries (vessels that will supply deoxygenated blood to the lungs) develop. [2] In certain heart conditions the pulmonary arteries do not develop. The collaterals continue to grow, and can become the main supply of blood to the ...
Pulmonary capillary hemangiomatosis (PCH) is a disease affecting the blood vessels of the lungs, where abnormal capillary proliferation and venous fibrous intimal thickening result in progressive increase in vascular resistance. [1] It is a rare cause of pulmonary hypertension, and occurs predominantly in young adults.
Chronic pulmonary aspergillosis is a long-term fungal infection caused by members of the genus Aspergillus—most commonly Aspergillus fumigatus. [8] The term describes several disease presentations with considerable overlap, ranging from an aspergilloma [12] —a clump of Aspergillus mold in the lungs—through to a subacute, invasive form known as chronic necrotizing pulmonary aspergillosis ...

Histopathology of aspergilloma, H&E staining. The most common organ affected by aspergilloma is the lung. Aspergilloma mainly affects people with underlying cavitary lung disease such as tuberculosis, sarcoidosis, bronchiectasis, cystic fibrosis and systemic immunodeficiency.
Low magnification micrograph of pneumatosis intestinalis in bowel wall.. Pneumoperitoneum (or peritoneal emphysema), air or gas in the abdominal cavity.The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma.
They can be either relatively slow-growing or malignant. However, aggressive fibromatosis is locally aggressive and invasive, with spindle-like growths. The tumors can lead to pain, life-threatening problems, or, rarely, death when they invade other soft tissue or compress vital organs such as intestines, kidneys, lungs, blood vessels, or nerves.
The diagnosis of microvascular angina (previously known as cardiac syndrome X – the rare coronary artery disease that is more common in females, as mentioned, is a diagnosis of exclusion. Therefore, usually, the same tests are used as in any person suspected of having coronary artery disease: [77] Intravascular ultrasound
