RESUMEN
We report a case of retroperitoneal hematoma during prophylactic heparin therapy for coronavirus disease 2019 (COVID-19). A 79-year-old man was diagnosed with COVID-19 pneumonia with possible exacerbation of fibrotic hypersensitivity pneumonia. He received a prophylactic dose of subcutaneous heparin therapy, methylprednisolone pulse therapy and Intravenous remdesivir but developed a spontaneous iliopsoas muscle hematoma, and transcatheter arterial embolization was performed. Even with a prophylactic dose of subcutaneous heparin therapy, the course should be carefully monitored, especially in patients with preexisting risk factors for hemorrhagic complications. Once retroperitoneal hematoma develops, aggressive procedures, such as transcatheter arterial embolization, should be considered to avoid fatal outcomes.

A 44-year-old man developed coronavirus disease 2019 (COVID-19) pneumonia during immunochemotherapy consisting of carboplatin, paclitaxel, and pembrolizumab for non-small cell lung cancer. Low-grade fever, followed by mild hypoxemia, and febrile neutropenia, were observed, and granulocyte colony-stimulating factor (G-CSF) was administered until the recovery of neutropenia, when he developed a high fever, severe hypoxemia, and hypotension accompanied by consolidation in the bilateral lungs. His conditions promptly improved after treatment including hydrocortisone and the primary and metastatic tumors remained regressed for 10 months without further treatment. Post-COVID-19 organizing pneumonia during cancer immunochemotherapy can be aggravated by immune-checkpoint inhibitors and G-CSF.

We report the first case of organizing pneumonia (OP) associated with a new coronavirus disease (COVID-19) vaccination. A 78-year-old woman developed cough and dyspnoea 10 days after receiving BNT162b2. Chest computed tomography (CT) revealed consolidation in the bilateral lower lobes of the lungs. Although antibiotic treatment did not improve her symptoms, she received a second vaccination as scheduled. She was referred to our hospital because of worsening dyspnoea on day 9 after the second vaccination, with reversed halo signs in the bilateral lower pulmonary lobes and new consolidation in the left lingual region on chest CT on day 15. She was diagnosed with OP based on bronchoalveolar lavage and transbronchial lung biopsy findings. Treatment with oral prednisolone 0.5 mg/kg/day immediately improved the symptoms and chest imaging findings. In the absence of other triggering factors, we considered this case as being COVID-19 vaccine-associated following the first and second vaccinations.
