Key Clinical Message: Systemic Lupus Erythematosus (SLE) can have an insidious onset and a fatal prognosis in children. Patients presenting without typical signs of SLE should undergo further evaluation if they are not responding to the initial diagnosis and treatment. This is especially true for patients with rapidly progressing symptoms and deterioration in spite of treatment. Pediatric Systemic Lupus Erythematosus is a chronic autoimmune disorder with various organ involvement pulmonary involvement in the course of this disorder is a rare yet potentially life‐threatening complication. In this case report we highlight the findings of a 16‐year‐old girl acutely and initially presenting with cough and fever, eventually complicating to diffuse alveolar hemorrhage and gradual loss of consciousness. Although the patient was started on immunosuppressive treatment after the diagnosis of lupus, based on renal and hematological impairment, was made and initially responded, she eventually deteriorated.

Purpose: Idiopathic intracranial hypertension (IIH) is a clinical syndrome that mimics brain tumors with increased intracranial pressure. The present study is designed to investigate the diagnostic criteria of magnetic resonance imaging (MRI) and the severity of cerebrospinal fluid (CSF) pressure to understand the relationship and frequency of these criteria with the level of CSF pressure. Methods: The present cross-sectional study was conducted on children diagnosed with IIH between the years 2011 and 2020, who were admitted to the pediatric neurology department of Ghaem Hospital, Mashhad, Iran. Clinical manifestations and imaging findings of the patients were recorded through a checklist. Results: Forty-nine patients were included in the study; 27 (55.1%) were male, and 22 (44.9%) were female. The average CSF pressure was 40.64±20.63 cmH2O. The mean diameter distension of the perioptic subarachnoid space was 6.02±1.21 mm. Six (10.8%) patients had unilateral transverse sinus stenosis with an average CSF pressure of 20.47±36.80 cmH2O and 11 (21.4%) patients had bilateral transverse sinus stenosis with an average pressure of 48.22±21.04 cmH2O. In 22 (44.89%) patients, flattening of the posterior globe with the CSF pressure of 48.80±17.94 cmH2O was reported. Twenty-four (49%) patients had optic nerve tortuosity, with an average CSF pressure of 46.52±20.33 cmH2O. Among the diagnostic criteria, the pressure had a significant relationship with the flattening of the posterior globe (P<0.022). Conclusion: Since MRI is a non-invasive method for examining IIH, the findings of this study may aid in diagnosing and monitoring these patients. [ABSTRACT FROM AUTHOR]
