Modified BLUE protocol ultrasonography can diagnose thrombotic complications of COVID-19 with normal lung ultrasound.

The BLUE protocol provides an excellent step-by-step approach for diagnosis of acute dyspnea. Adding FECHO (Focused Echocardiography) to the BLUE protocol completes the picture and helps make solid diagnoses, especially in submassive and massive PE (Pulmonary embolism). COVID-19 infection can present with thrombotic manifestations like DVT (Deep vein thrombosis) and PE with no ultrasonographic evidence of lung parenchymal affection.

Carbamazepine-induced Stevens-Johnson syndrome in a patient with history of methotrexate-induced mast cell activation syndrome.

Stevens-Johnson syndrome (SJS) is serious conditions that happen as a result of infection, side effects to medications, or unknown etiology. Carbamazepine is one of the common medications that can cause SJS. Good history taking is crucial if treatment with carbamazepine is clinically indicated.

White lung with milky effusion.

Thoracic duct injury is a rare complication of dorsal spine operations. Ultrasound chest plays an important tool for rapid diagnosis of acute dyspnea, drainage of massive effusion, and daily follow-up. Conservative treatment of postoperative chylous with measures to decrease chylous formation can lead to a resolution of chylothorax.
