The presence of lymphocytic pleocytosis is generally detected through a lumbar puncture followed by clinical analysis of cerebrospinal fluid. When combined with analysis of the appearance and pressure of the tested CSF, along with measurements for the amount of glucose and proteins present, white blood cell counts can be used to detect or ...

Ultrasound-guided lumbar puncture is a medical procedure used in some emergency departments to obtain cerebrospinal fluid for diagnostic purposes. In contrast to standard lumbar puncture by palpation , the use of ultrasound imaging may reduce the number of failed punctures, needle insertions, and needle redirections. [ 1 ]
Intracranial hypertension (IH), also called increased ICP (IICP) or raised intracranial pressure (RICP), refers to elevated pressure in the cranium. 20–25 mmHg is the upper limit of normal at which treatment is necessary, though it is common to use 15 mmHg as the threshold for beginning treatment.
A lumbar puncture can give the symptom of a post-dural-puncture headache. A cerebrospinal fluid leak can be either cranial or spinal, and these are two different disorders. [5] A spinal CSF leak can be caused by one or more meningeal diverticula or CSF-venous fistulas not associated with an epidural leak.
There are no specific signs or symptoms that can indicate meningitis, and a lumbar puncture (spinal tap) to examine the cerebrospinal fluid is recommended for diagnosis. [47] Lumbar puncture is contraindicated if there is a mass in the brain (tumor or abscess) or the intracranial pressure (ICP) is elevated, as it may lead to brain herniation.
The procedure is most often used to relieve PDPH following an epidural injection or lumbar puncture. Diagram of epidural catheter placement. Post dural puncture headache (PDPH) is a side of effect of spinal anesthesia, where the clinician accidentally punctures the dura with the spinal needle and causes leakage of CSF. Factors such as pregnancy ...
