A rare syndrome of hypertension, seizures and intracranial bleed has been reported among patients with congenital hemolytic anemia who underwent multiple blood transfusions. We report this syndrome in a 12-year-old Malay girl with hemoglobin E-beta-thalassemia, who underwent intensive transfusion and subsequently had headache, visual loss, severe hypertension and seizures. A comprehensive literature review revealed 30 patients with this syndrome, of whom 15 had intracranial bleed and 12 among these 15 died. A less-intensive transfusion regimen among patients with chronic hemolytic anemia and prompt detection and management of hypertension may prevent this potentially fatal syndrome.
BACKGROUND: Hypercalcemia is common in primary hyperparathyroidism malignancies and even in tuberculosis. Interestingly, systemic lupus erythematosus (SLE) rarely presents with hypercalcemia.
CASE REPORT: We describe an interesting case of SLE in a patient who was otherwise thought to have either tuberculosis or a malignancy. The patient initially presented with feeling unwell, with generalized lymphadenopathy, bilateral pleural effusion, and bilateral corneal calcium deposits secondary to severe hypercalcemia. The diagnosis of SLE was made based on positivity of antinuclear antibodies (ANA) and anti-dsDNA, the presence of serositis, lymphadenopathy, autoimmune hemolytic anemia, and constitutional symptoms. She was treated with steroids, with tremendous improvement in her general well-being, resolution of lymphadenopathy and pleural effusion, and normalization of her hemoglobin and serum calcium. The atypical presentation of SLE with hypercalcemia with pleural effusion is discussed.
CONCLUSIONS: SLE should be one of the differential diagnoses in patients presenting with severe hypercalcemia.

Idiopathic hypereosinophilic syndrome (HES) is an uncommon disorder which usually presents with prolonged and significant primary eosinophilia with end-organ dysfunction. Damaging proteins released by the eosinophilic granules are responsible for the tissues and organ system damage. Here we report two cases of idiopathic HES. Both the patients were young lady presented with high grade fever and concomitant symptoms. Laboratory findings showed leucocytosis with predominant neutrophilia and marked eosinophilia. A diagnosis of idiopathic HES was made after excluding secondary causes of eosinophilia. However, the first patient was complicated with multiple venous thrombosis and intravenous heparin was started which was later changed to subcutaneous low molecular weight heparin (LMWH). The patient developed pleural effusion and consolidation. Intravenous Tazoscin, tablet Prednisolone and tablet Hydroxyurea was started and the patient responded well. Despite treatment, two weeks later, suddenly the patient collapsed and unfortunately succumbed. On the other hand, the second patient was complicated with fever, thrombocytopenia, haemolytic anaemia, acute renal failure and neurological deficit which were part and parcel of thrombotic thrombocytopenic purpura (TTP). Plasma exchange was commenced and patient’s condition had slowly improved. Nevertheless, the hypoxia which she sustained during the multiple episodes of fits had resulted in permanent brain injury and thus requiring a tracheostomy for prolonged ventilatory support. Currently, there is no cure for HES. The main aim of treatment is to minimise the tissue damage caused by the hypereosinophilia. Early diagnosis and intervention are therefore crucial in preventing the spread of the disease and the end-organ damage.
Vitamin B12 deficiency and folate deficiency are common causes of macrocytic anaemia and both are important for many cellular processes. These deficiencies could be due to inadequate dietary intake, impaired absorption or drug ingestion. We present a case of a 47-year-old male with a history of diffuse large B-cell lymphoma (DLBCL) who was admitted for fatigue, persistent frontal headache and left upper-quadrant abdominal pain. Further investigation showed that he had pancytopenia with microangiopathic haemolytic anaemia (MAHA) and intracranial bleeding (ICB). Serum vitamin B12 and folate were later found to be low and a diagnosis of combined vitamin B12 and folate deficiency mimicking thrombotic thrombocytopenic purpura (TTP) was made. The patient responded well to vitamin B12 and folate replacement.
Extramedullary hematopoiesis (EH) is a rare but well-known compensatory mechanism of red blood cell production when the normal site of red bone marrow is unable to produce sufficient number of red blood cells. When the body demands for erythrocyte cells is high this lead to EH. This occurs mainly outside the bone marrow, usually paraspinally and sites which are normally observed in the fetus as in the liver, spleen, lymph nodes and less frequently at other sites such as adrenal, thymus, kidneys, pleura, breast, skin, gastrointestinal tract, dura mater and brain.This is more frequent in thalassaemia major (incidence up to 15% of cases), in myelofibrosis, myeloproliferative diseases (polycythemia rubra vera, chronic myeloid leukemia,), hemolytic anemias such as hereditary spherocytosis, pyruvate-kinase deficiency, medullary tuberculosis and in Paget’s disease of the bone. In some cases the cause of the EH are not identified [3]. We describe a case of EH in the presacral space that mimicked an ovarian mass on ultrasound in a patient with beta-thalassaemia intermedia.
Cerebral Venous Thrombosis in patients with Evan’s Syndrome of autoimmune hemolytic anemia is rare. The
common neurological symptoms are headaches, vision loss, dyslexia without agraphia, motor aphasia,
unilateral upper limb weakness and papilloedema. We present a case report of a lady with a known case of
Evan’s Syndrome whom presented with severe anemia and unilateral right sided hemiparesis with right facial
weakness. Plain and Contrast enhanced CT brain showed bilateral high parietal white matter edema with
venous thrombosis in the right transverse and superior sagittal venous sinuses. At the time of the diagnosis,
she was in hematological remission.
