Chronological timeline of clinical events in the present case.
| Time point | Clinical events |
|---|---|
| 4 years before surgery | CT-guided biopsy diagnosed a solitary fibrous tumor (SFT) of the left lower lobe; surgery was initially deferred. |
| Follow-up period | Progressive tumor growth observed on imaging. |
| Preoperative evaluation | Progressive exertional dyspnea; CT revealed a large pulmonary mass measuring approximately 15 × 14.5 × 12.5 cm. The multidisciplinary tumor board recommended surgical resection. |
| Preoperative workup | Pulmonary function testing, bronchoscopy, echocardiography, and abdominal imaging were performed; pancreatic cystic lesions consistent with side-branch IPMN were detected without worrisome features. |
| Day of surgery | Open left lower lobectomy with mediastinal lymphadenectomy performed. |
| Postoperative day 0 | Initial extubation following surgery. |
| Early postoperative period | Cardiopulmonary instability requiring re-intubation and cardiopulmonary resuscitation. |
| Postoperative day 5 | Successful extubation following stabilization. |
| Postoperative imaging | CT revealed a small peripheral pulmonary embolism; anticoagulation therapy was initiated. |
| Postoperative day 12 | Transfer from intensive care to the surgical ward. |
| Postoperative day 16 | Patient discharged in stable condition. |
| 3-month follow-up | Clinical improvement with no evidence of recurrence or metastasis on CT imaging. |
CT: computed tomography; IPMN: intraductal papillary mucinous neoplasm.
