Giant Cell Arteritis Presenting with Bilateral Subdural Haematomas of Arterial Origin

Giant cell arteritis or temporal arteritis is an inflammatory condition affecting medium to large sized vessels, particularly the cranial arteries. A 76-year-old man with no significant past medical history presented to the emergency department with a 3-week history of diffuse headaches associated with fever, loss of appetite, weight loss and general malaise. A CT scan of the brain showed bilateral shallow chronic low density subdural haematomas. A complete laboratory panel was unremarkable except for a raised erythrocyte sedimentation rate and elevated C-reactive protein. A transthoracic echocardiogram and CT scan of the body were unremarkable. MRI of the brain confirmed bilateral old subdural collections and showed marked vessel wall enhancement in the frontal branches of the left superficial temporal artery. A left temporal artery biopsy confirmed giant cell temporal arteritis. We speculate that a vasculitic process in the small subdural arteries may have contributed to our patient’s spontaneous subdural haematomas.

Intravascular Lymphoma as an Uncommon Cause of Anasarca

Objectives: To report a case of intravascular lymphoma (IVL) in a Caucasian patient who presented with anasarca as his sole clinical sign. Material and Methods: A man presented with anasarca-type oedema and fatigue. After excluding heart failure, hepatic cirrhosis, nephrotic syndrome, hypothyroidism, AL-amyloidosis and adverse drug reaction which can all cause oedema, we turned our attention to capillary permeability disorders. Results: Closer review of the bone marrow aspirate demonstrated haemophagocytic histiocytosis, while core, renal and duodenal biopsies showed a B-cell IVL. Conclusion: The differential diagnosis of anasarca, a relatively common clinical sign, should include IVL although the diagnosis may still be challenging.
