Based on the imaging findings of COVID-19 and pulmonary tuberculosis the main differentiating feature on imaging in active infective stages is presence or lack of mediastinal lymphadenopathy.We encountered a diagnostic dilemma when we received a patient for CT-Chest during the ongoing Novel-coronavirus pandemic.Chest radiographs showed patchy areas of consolidation in both lungs.CT-Chest revealed multiple necrotic mediastinal lymphnodes along with patchy areas of consolidation in both lungs.

Background: Phototherapy is a commonly used treatment for neonatal hyperbilirubinemia.Hypocalcemia is a known adverse effect of phototherapy.We conducted this study to measure the efficacy and safety of head covering in prevention of phototherapy-induced hypocalcemia.Material and Methods: A total 210 newborns of >35 wk gestation with neonatal jaundice were included in the study.They were randomized into two equal groups- group A underwent phototherapy without any head cover while the heads of newborns in group B was covered with a cap.In both the groups, ionized serum calcium was measured at the start of phototherapy and at 48 h.Results: The mean decline in ionized serum calcium in group A was 0.63mg/dL while in group B it was 0.34mg/dL.The incidence of hypocalcemia in the group A without head covering was 27.6 % (29 cases) while in group B with head cover was 10.5 % (11 cases).Conclusion: Phototherapy can cause hypocalcemia in a significant proportion of newborns.Monitoring of serum calcium during phototherapy is desirable to detect hypocalcemia.Use of a head cover during phototherapy appears to be a safe and effective intervention for prevention of phototherapy-induced hypocalcemia.
