Wedge Shaped Infarct in the Spleen |
The CTscan with contrast shows a wedge shaped defect in the spleen (overlaid in pink in middle image) characteristic of an acute infarction most commonly caused by emboli. The pathology image from a different patient shows the same wedge shaped process.

![]() Breast Carcinoma and Pulmonary Emboli |
This CT is from an elderly lady wih breast carcinoma, who presents with SOB . Noted are filling defects in the pulmonary arteries (white arrow). The left sided pulmonary arteries also have filling defects. (see next set of images) She has had a left mastectomy, (green arrow) and has lytic metastases of the left ribs with destruction of the bone which remain as two white calcific specks (teal blue arrow). A small pleural effusion on the left may be due to the malignancy (likely) or due to the pulmonary embolus.

![]() Pulmonary Emboli Before and After Treatment |
The patient has breast carcinoma and was shown in the set of images above. She presented with shortness of breath and pulmonary emboli were diagnosed as filling defects (overlay in royal blue c), in all the visualized vessels. After 2 weeks of anticiacougulant therapy the emboli were lysed and the vessels were completely patent (overlaid in red in d)

![]() PE from Upper Limb Thrombosis |
This elderly woman presented with acute respiratory difficulty with swelling of her left upper limb. CT shows extensive pulmonary embolic disease to the lower lobes from second order branches to the tertiary branches (1-4 with green overlay) and evidence of thrombosis of the left subclavian vein. (5,6). Swelling over the anterior chest including the pectoralis muscles is evident in 7. Courtesy Priscilla Slanetz MD. 32538cLW |
![]() Football Player with a Comminuted Fracture and Fat Embolism |
21 year old college student and football player who sustained a compound fracture of his right tibia and fibula. While awaiting surgery he became short of breasth, tachpneic and tachycardic and his saturations dropped to 70’s from 90’s on room air. He had a fever to 103, heart rate of 100, respiratory rate of 30, and a systolic pressure of 140. He required intubation for 5 days but did recover thereafter.
