<s>[INST] I have multiple pulmonary embolisms in right upper and lower lobes, only symptom prior to diagnosis SOB. Hemoglobin 10.5, eosinophils low, otherwise CBC within normal ranges. 53 years old. No DVTs, no history of PEs, facotr V leiden negative. Im trying to figure out cause. Some physicial changes point towards Cushings. Have history of parathyroid adenoma. Worried about malignancy. [/INST] Thanks for your question on Chat Doctor. Pulmonary embolism without DVT (Deep venous thrombosis) is less likely due to malignancy. So no need to worry much for malignancy as a cause. There are other causes like1. Connective tissue diseases2. Storage diseases3. Primary pulmonary hypertension. 4. Protein C deficiency. 5. Protein S deficiency. 6. Hypervitaminosis k.7. HIV infection etc. So better to rule out these causes first. </s>
