INTRODUCTION: Sclerotherapy is a widely used as a lifesaving therapeutic option in cases of upper gastrointestinal bleeding (UGB) due to ruptured gastro-esophageal varices (GOV) in cirrhotic patients, especially when there exists a portosystemic shunt. This endoscopic technique can entail many complications, including systemic and non-thrombotic pulmonary embolism (PE). While multiple pulmonary parenchymal manifestations have been described following sclerotherapy of GOV, to our knowledge no solitary suspicious pulmonary nodule has been described.
CASE PRESENTATION: We report the case of 55-year-old man with heavy smoking history who was referred to our pulmonary clinic for work-up of a solitary pulmonary nodule. He was known to have liver cirrhosis with history of massive UGB due to rupture of GOV two months before. He was treated with sclerotherapy by injecting a 3 cc of Histoacryl/lipiodole solution. The post- endoscopic phase was unremarkable. An enhanced CT scan of chest and abdomen performed two months later showed a right upper lobe nodule, even though at that point, the patient was completely asymptomatic. This was ascribed to non-thrombotic PE secondary to sclerotherapy due to complete resolution of the nodule on a CT scan carried out at 2-month follow-up. At that point, his condition did not require any further treatment.
CONCLUSION: Solitary pulmonary nodule is one of the radiologic manifestations of PE subsequent to sclerotherapy of GOV. Awareness and radiologic follow-up of this unusual radiologic presentation may prevent unnecessary biopsies.
