Thin section CT shows bilateral tree-in-bud opacities and a cavitary masslike consolidation in the right upper lobe Conclusion The imaging findings in this viral pneumonia showed a broad spectrum which indicate a considerable overlap with various infectious and non-infectious etiologies.

It represents dilated and impacted mucus or pus-filled centrilobular bronchioles. Thus the bronchioles resemble a branching or budding tree and are usually somewhat nodular in appearance. The relative frequency of tree-in-bud opacities in the clinical setting has been evaluated by Miller and Panosian 27.

Frequency and significance on thin section CT.

When accompanied by acute or recent aspiration centrilobular ground-glass and tree-in-bud nodules are common in the bronchocentric areas of the lower lobes and the dependent upper lobes. However the most common process leading to this CT appearance is infection.

Tree-in-bud describes the appearance of an irregular and often nodular branching structure most easily identified in the lung periphery. Radiology scientific expert review panel. Multiple centrilobular nodules many with a tree in bud type configuration with minor ground glass opacity are identified involving primarily the lateral aspect of the left lower lobe.

Hrct plays a vital role in differentiating granulomatous processes from other dplds17although the features of tb such as centrilobular nodularity and tree in bud appearances are not pathognomonic they are distinctive enough to strongly suggest tb910presence of lymphadenopathy calcified or otherwise consolidation cavitation and the.
