Stroke as an unusual initial presentation of 'malignant' middle cerebral artery infarction involvement in systemic lupus erythematosus.

Introduction and importance: SLE, or systemic lupus erythematosus, is a chronic autoimmune condition of uncertain origin characterized by the presence of autoantibodies that target the body's own antigens. Case presentation: A 16-year-old female presented at the emergency room with a right-sided lip droop and subsequently developed symptoms consistent with a malignant hemispheric infarction, including altered consciousness, hemiplegia, and forced gaze deviation. Her laboratory results were within the normal range. However, a brain MRI revealed cerebral edema and a massive infarction in the middle cerebral artery (MCA) region. Subsequently, her serologic profile was indicative of SLE, leading to a later diagnosis. Clinical discussion: The patient in this case presented with symptoms suggestive of a stroke. A CT scan showed MCA occlusion, leading to a diagnosis of malignant MCA syndrome. The patient was also diagnosed with systemic lupus erythematosus, which is associated with an increased risk of stroke. Inflammation-induced thrombosis and CNS vasculitis are potential mechanisms linking SLE and stroke. Conclusion: This case serves as an example of a sudden and potentially life-threatening presentation of SLE, underscoring the importance of early detection and targeted treatment that can influence the course of the disease.

Unusual initial presentation of childhood acute lymphoblastic leukemia as massive ascites and pleural effusion in post-COVID-19 setting: a case report.

Acute lymphoblastic leukemia (ALL) in children typically presents with nonspecific manifestations such as fever, fatigue, lethargy, joint and bone pain, and bleeding diathesis. Ascites and pleural effusion as an initial presentation of ALL, although described, is exceedingly rare. However, this unusual initial presentation becomes much rarer in the post-coronavirus disease 2019 (COVID-19) setting. Herein, we aim to highlight such a rare initial presentation of childhood ALL that warrants clinical attention. Case Presentation: Two months following a COVID-19 infection, a 3-year-old male patient presented to the hospital with severe abdominal distention associated with occasional dyspnea. Physical assessment revealed a critically ill and pale patient with a distended abdomen and decreased air entry on the right side of the chest. Laboratory testing showed pancytopenia. Imaging studies confirmed the presence of massive ascites and pleural effusion. Bone marrow aspiration revealed CD10-positive pre-B-cell ALL. The patient was treated with chemotherapy and achieved complete remission. Conclusion: Rare manifestations of relatively common diseases create a barrier to prompt and effective detection and medical intervention. Although ascites and pleural effusion are rare conditions in ALL children patients, the occurrence of these pathologies in this particular patient, especially following COVID-19 infection, is an exceedingly rare event.
