Masquerading as Pneumonia: A Lung Neuroendocrine Tumor Case Report.

The presentation of recurrent pneumonia, particularly in the same lobe, should raise suspicion for possible neuroendocrine tumors of the lung within that respective lobe. Commonly, these types of tumors will have a gastrointestinal origin with a larger incidence of carcinoid syndrome, but they may also originate in the pancreas or lungs. This case illustrates the potential for a masked lung tumor in an otherwise young and healthy 31-year-old patient, with a short history of tobacco dependence and unremarkable family history, who presents with recurrent pneumonia and dyspnea. Although rare in itself, this case was even more unique due to the partial calcification of the neuroendocrine tumor mass along with causing a collapse in the entire right middle lobe.

A Unique Case of Spontaneous Pneumomediastinum in a Patient With COVID-19 and Influenza Coinfection.

Spontaneous pneumomediastinum is reported in patients with coronavirus disease-2019 (COVID-19) and influenza infection independently, usually associated with noninvasive and mechanical ventilation. We report a case of spontaneous pneumomediastinum in a patient with COVID-19 and influenza coinfection. A 58-year-old male admitted with shortness of breath, diagnosed with COVID-19 and influenza infection. A computed tomography angiogram showed pneumomediastinum. He was treated conservatively with 15 L of oxygen, remdesivir, convalescent plasma, and oseltamivir. The case is being reported for its uniqueness since this is the first documented case of spontaneous pneumomediastinum in COVID-19 and influenza coinfection.

Isolated Radial Vein Thrombosis: Upper Extremity Deep Vein Thrombosis in a Patient With COVID-19 Infection.

In general, upper extremity deep vein thrombosis (DVT) is less common than lower extremity DVT. Among upper extremity DVT cases, most of them are due to secondary causes like indwelling catheters, cancer, surgery, trauma or immobilization by plaster casts, pregnancy, oral contraceptives, and estrogen. Patients with coronavirus disease 2019 (COVID-19) infection are known to have coagulation dysfunction and a high incidence of DVT, mostly in the lower extremities; however, upper extremity DVT has been rarely reported. We present a rare case of upper extremity DVT in COVID-19 infection. A 56-year-old male with no significant past medical history was admitted with acute respiratory failure due to COVID-19 pneumonia. During hospitalization, he developed right upper extremity swelling, and an ultrasonogram showed right radial vein thrombosis. He was initially started on low molecular weight heparin (LMWH) and was discharged on apixaban. Patients with COVID-19 infection who develop DVT are recommended treatment with a direct oral anticoagulant (DOAC) for three months.
