Extramedullary hematopoiesis in ribs and severe pulmonary hypertension disease following intermediate beta-thalassemia: a case report.

BACKGROUND: Thalassemia is a type of congenital hemoglobinopathy that falls into the category of hemolytic anemias. Extramedullary hematopoiesis is a complication of this disease, which is a mechanism to compensate for chronic anemia in these patients, and imaging is the best diagnostic method. CASE REPORT: In this report, a 36-year-old Caucasian female patient with intermediate beta thalassemia is presented who, at the time of referral, complained of exacerbated shortness of breath. Imaging showed diffuse expansion masses with soft tissue components in the ribs of both hemithoraxes, leading to the diagnosis of extramedullary hematopoiesis. CONCLUSION: Extramedullary hematopoiesis in the ribs is an uncommon finding in patients with thalassemia and is a sign of the severity of the disease and a poor prognostic factor that might be preventable if blood transfusion begins at younger ages.

A Case of Acute Respiratory Distress Syndrome Following Pleurodesis With Talc.

Management of malignant pleural effusion is a medical challenge, and several methods have been proposed to deal with it including thoracentesis, indwelling pleural catheter placement, and chemical or mechanical pleurodesis. Each method, however, has its advantages and disadvantages. Talc pleurodesis is generally recognized as the most effective and safest method for the induction of chemical pleurodesis. However, in rare cases, it can lead to acute respiratory distress syndrome (ARDS). In this article, we report the case of a patient with metastatic adenocarcinoma to the pleura who presents with shortness of breath and malignant pleural effusion, develops ARDS after pleurodesis with talc, and expires despite the partial improvement of lung involvement. The symptoms and causes of this rare side effect as well as the methods that can be used to deal with it are reviewed in this article.
