Background: Spontaneous intracranial hypotension (SIH) is a rare condition resulting from cerebrospinal fluid (CSF) volume depletion, nearly always from spontaneous CSF leaks. CSF pressure in SIH is usually normal; low CSF pressure is found in a substantial minority of patients. SIH is uncommonly described in pregnancy.
Case Series: Five women with SIH during pregnancy have been conservatively treated adopting bed rest and overhydration. After prolonged conservative treatment, only 1 patient showed complete symptoms resolution. A rare SIH complication as cerebral venous thrombosis has been reported in 1 case. All 4 remaining patients had lumbar epidural blood patch (EBP) with symptoms disappearance.
Conclusions: EBP might be proposed to SIH patients also during pregnancy and after a brief period (~10 days) of ineffective conservative treatment, because it could allow faster symptoms improvement and complete recovery. Furthermore, EBP would avoid prolonged bed rest with the risk of SIH severe complications.

BACKGROUND Ureaplasma urealyticum (UU) is a common microorganism that has been associated with a variety of obstetric and neonatal complications, such as infertility, stillbirth, histologic chorioamnionitis, neonatal sepsis, respiratory infections, and central nervous system infections. However, it is rare for it to cause severe neonatal asphyxia. This rarity is the focus of our case report, which aims to highlight the potential severity of UU infections in newborns.

Background: Cerebrospinal fluid (CSF) loss in spontaneous intracranial hypotension (SIH) is accompanied by volume shifts between the intracranial compartments. This study investigated tricompartimental and longitudinal volume shifts after closure of a CSF leak.
Methods: Patients with SIH and suitable pre-therapeutic and post-therapeutic imaging for volumetric analysis were identified from our tertiary care center between 2020 and 2023.

A potential two-way passage of cells and substances between the brain and skull bone marrow may open for new insights into neurological disease. The arachnoid membrane was traditionally considered to restrict cells and larger molecules in CSF from entering the dura and bone marrow directly. However, new data on exchange between brain and skull bone marrow have recently emerged.

Hypoxic-ischemic brain injury (HIBI) is a feared complication post-cardiac arrest (CA). The timing of brain imaging remains a topic of ongoing debate. Early computed tomography (CT) scans can reveal acute intracranial pathologies but may have limited predictive value due to delayed manifestation of HIBI-related changes.

Background And Purpose: Symptoms indistinguishable from behavioral-variant frontotemporal dementia (bvFTD) can develop in patients with spontaneous intracranial hypotension associated with severe brain sagging. An underlying spinal CSF leak can be identified in only a minority of these patients and the success rate of nondirected treatments, such as epidural blood patching and dural reduction surgery, is low. The disability associated with bvFTD sagging brain syndrome is high and, because of the importance of the venous system in the pathophysiology of CSF leaks in general, we have investigated the systemic venous circulation in those patients with recalcitrant symptoms.
