The liver function test (LFT) is a commonly performed test in clinical practice in order to assess well-being of the liver; however, derangement in liver enzymes, however, may not necessarily imply an underlying liver pathology. The standard liver function test measures alanine aminotransferase (ALT), aspartate aminotransferase (AST), alanine phosphatase (ALP), bilirubin levels (total, direct, and indirect), proteins (total protein and albumin), and PT-INR (prothrombin time and international normalized ratio). In addition to common causes, liver enzyme levels can also be elevated due to extrahepatic causes, such as muscular injury can elevate transaminases levels. Here in, we present a case of an asymptomatic healthy male who was doing vigorous exercise and presented with reports of elevated transaminase levels. During evaluation of the case, most of his reports came to be within normal range. Additionally, when reevaluated after discontinuation of vigorous exercise, 3 weeks later and then a month later, his liver enzyme levels were observed to be within normal range. Hence, we suspect that muscle damage-induced transaminitis might not have been considered in the differential diagnosis during the evaluation of a patient with raised transaminases levels and also suggest that it should be kept as a differential in the given scenario.

Background Waldenström macroglobulinemia is a rare hematological malignancy and is the most common diagnosis in patients with hyperviscosity syndrome. Bilateral central retinal vein occlusion as an initial presentation of hyperviscosity syndrome in Waldenström macroglobulinemia is rare. Case presentation A 42-year-old Nepalese male presented with sudden-onset bilateral painless blurring of vision. Fundus examination revealed bilateral, diffusely dilated, tortuous retinal veins and intraretinal deep blot hemorrhages in all four quadrants of the retina in both eyes; features of bilateral central retinal vein occlusion. Serum electrophoresis showed hypoalbuminemia with an immunoglobulin M kappa monoclonal spike. Bone marrow picture and immunohistochemistry analysis were suggestive of lymphoplasmacytic lymphoma. The patient received systemic therapy for Waldenström macroglobulinemia, along with intravitreal bevacizumab. Conclusion Adequate hydration, plasmapheresis, and a combination of bortezomib, dexamethasone, and rituximab regimen as a systemic therapy may represent an ideal choice for patients with hyperviscosity in Waldenström macroglobulinemia.
