“…In reply: We agree with Morgan that the symptoms, signs and laboratory investigations in our case report, although non‐specific, supported a diagnosis of infection 1 . The C‐reactive protein level was not available for 24 hours.…”

“…Eleven patients with pSAH related to infectious etiologies were discovered across 10 manuscripts [ Table 3 ]. [ 12 , 13 , 16 , 18 , 20 , 23 , 25 , 32 , 44 , 65 ] The most common infectious etiologies included pneumococcal meningitis in three patients, cryptococcal meningitis in two patients, and viral meningoencephalitis in two patients. Radiographic investigations besides CT included CTA, CT perfusion, MRI, MR angiography, and MR venography, as well as one case in which a diagnostic cerebral angiogram was utilized.…”

Background: Patients with computed tomography (CT) findings consistent with subarachnoid hemorrhage without evidence of hemorrhage following autopsy or cerebrospinal fluid testing are termed to have pseudosubarachnoid hemorrhage (pSAH). Methods: A systematic review of literature was conducted based on the preferred reporting items for systematic reviews and meta-analysis statement. Studies were evaluated for associated cause of pSAH, imaging modality used in assessment, method of confirmatory testing, and clinical outcome. Results: Fifty studies were included in qualitative analysis including 197 cases of pSAH. Systematic review revealed 23 studies including 110 patients with pSAH attributed to hypoxic-ischemic brain injury following cardiac arrest. Three studies were included in meta-analysis that quantitatively analyzed differences in CT densities in patients with pSAH and true subarachnoid hemorrhage (true SAH). A random effects model meta-analysis showed a statistically significant decrease in densities in the Sylvian fissure in patients with pSAH compared to true SAH and a statistically significant decrease in densities in adjacent parenchyma in patients with pSAH compared to true SAH. Systematic review further revealed 32 patients with pSAH associated with spontaneous intracranial hypotension, 11 patients with pSAH related to infectious etiologies, 15 patients with pSAH associated with subdural hemorrhage, 20 cases of pSAH related to hyperhemoglobinemia, 2 cases related to valproate toxicity, and individual cases related to hyponatremia, diabetic ketoacidosis, sudden infant death syndrome, cerebellar infarction, and dialysis disequilibrium syndrome. Conclusion: This study is the first systematic review of causes, diagnostic modalities, and outcomes in patients who present with pSAH. A diagnosis of pSAH may be considered following assessment of CT densities following cardiac arrest.

“…La pseudo HSA también ha sido descrita en otras patologías: hematoma subdural, edema cerebral en insuficiencia hepática fulminante, trombosis de seno venoso, post angiografía y en meningitis bacteriana (13) . En este último caso, el alto contenido proteico del LCR purulento determina el aspecto hiperdenso del espacio subaracnoídeo (11) .…”

“…Se han descrito algunas patologías neurológicas en las cuales la TC de encéfalo muestra patrones tomográficos similares a los de la HSA, sin que exista evidencia clínica ni anatomopatológica de hemorragia, esta condición ha sido denominado pseudo hemorragia subaracnoidea (pseudo HSA) (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) .…”

Some catastrophic diseases of the central nervous system can simulate the tomographic pattern of the subarachnoid hemorrhage; the most frequent is the hypoxic-ischemic encephalopathy. The recognition of this entity by the physicians can prevent an aggressive study and treatment of this group of patients. We present a case with clinical and tomographic probably diagnosis but without final confirmation by cerebrospinal fluid analysis or autopsy. A patient who developed a hypoxic-ischemic encephalopathy, three days after, his brain computed tomography showed a pseudo subarachnoid hemorrhage imaging.
