[ 4 ] In our case, the patient had no history of trauma neither was in any exertional activity during the event of headache. There was a spontaneous severe bursting headache in lying posture while resting.…”

Ghost aneurysm in atraumatic acute subdural hematoma: A sign of caution or a mere finding – A case report

Atraumatic subdural bleed often presents with diagnostic and management dilemma. This is a case of a 36-year male who presented with acute onset headache while at rest without any focal neurodeficit. Computed Tomographic Scan of brain revealed subdural hematoma. Cerebral Digital Subtraction Angiography showed a same sided focal dye extravasation which corresponded exactly to the inner margin of the subdural bleed. Though the patient opted out for surgical management this imaging and DSA finding correlated with the “Ghost Aneurysm” concept in acute atraumatic subdural bleeds and its early recognition is an important imaging marker for caution for hematoma expansion.

“…In the human literature, one‐third of patients with polycythaemia vera were reported to experience a cerebral thrombotic event before the diagnosis 11,12,32 . Haemorrhage secondary to erythrocytosis was reported in a low number of human cases diagnosed with primary erythrocytosis; cerebral, subdural, spinal cord and/or mucocutaneous bleeding have been observed 13–15,33,34 . The exact mechanism of the haemorrhagic event remains unclear; however, it was speculated that an increase of circulating platelets might result in an increased absorption of von Willebrand factor multimers in the platelet membranes 34,35 .…”

“…9 Interestingly, in humans with primary erythrocytosis, ischaemic stroke is the only presenting complaint in up to 15% of cases. 11,12 In contrast, central nervous system (CNS) haemorrhage has been infrequently reported in humans, [13][14][15] and to date, there are no reports describing CNS haemorrhage in dogs due to erythrocytosis. This case report describes the clinical presentation, diagnostic investigations and outcome of two dogs with multifocal cerebral haemorrhage due to erythrocytosis.…”

An 8‐month‐old, female toy poodle and a 5‐year‐3‐month‐old, male, neutered Bernese Mountain dog presented with acute onset, progressive neurological deficits. Neurological examination findings were consistent with multifocal forebrain, brainstem and potential C1–C5 spinal cord segment involvement in both dogs. The toy poodle had a packed cell volume of 85% on presentation, and rapidly deteriorated to cardiopulmonary arrest. Postmortem examination revealed multifocal leptomeningeal, white and grey matter haemorrhage. Femoral bone marrow analysis revealed 95%:5% haematopoietic:fat ratio (reference value: 80%:20%). The Bernese Mountain dog had an initial packed cell volume of 81%. Magnetic resonance imaging of the head identified multifocal cerebral haemorrhage. The erythrocytosis was believed to be secondary to marked bilateral nephropathy. Following two phlebotomies, the packed cell volume decreased to 78%. However, the dog deteriorated and had a cardiopulmonary arrest. We report two clinical cases in which erythrocytosis was the cause of rapid and severe neurological deterioration.

Background: There is sparsity of data on outcomes following joint arthroplasty among polycythemia vera (PV) patients. The aim of this study is to evaluate postoperative outcomes following primary total knee (TKA) and hip (THA) arthroplasty among PV patients. Methods: A retrospective Medicare database review identified 6932 PV patients who underwent a primary total joint arthroplasty (4643 TKAs and 2289 THAs) from 2006 to 2013. A comparison of hospital length of stay, mortality, and the diagnosis of surgical site infections (SSIs), stroke, myocardial infarction, acute pulmonary embolism (PE), deep vein thrombosis (DVT), and other postoperative complications was made between PV patients undergoing TKA and THA and their respective matched control groups. Results: PV was significantly associated with increased rates of acute PE (2.3% vs 1.6%; odds ratio [OR] 1.44, 95% confidence interval [
