Acute compressive ulnar neuropathy in dengue fever
Dengue haemorrhagic fever is known for its haemorrhagic and neurologic complications. Neurologic complications are caused by three mechanism namely neurotropism, systemic complications causing encephalopathy and postinfectious immune-mediated mechanisms.

Published in the Journal of Orthopaedic Case Reports, the authors report a case of acute compressive ulnar neuropathy due to peri neural hematoma, following an attempt at intravenous cannulation in the cubital fossa in a patient of dengue haemorrhagic fever with thrombocytopenia. Immediate fasciotomy and removal of haematoma was performed to relieve the symptoms.

Key takeaway:-
Compression peripheral neuropathies may occur in dengue fever and should be distinguished from direct neurological involvement as the compression neuropathies will require urgent decompression while treatment of other neurological features is mostly supportive in dengue fever.
