Background: Cerebrospinal fluid (CSF) leaks and pneumocephalus commonly occur due to head trauma or surgical procedures. Spontaneous CSF (sCSF) leaks, however, occur without any clear etiology and are relatively uncommon. Case Description: An 84-year-old woman presented with the right-sided otorrhea. The patient had a history of a ventriculoperitoneal shunt placement following a subarachnoid hemorrhage treated by clip ligation of a left-sided ruptured cerebral aneurysm 7 years before presentation, with shunt catheter ligation after evidence of intraventricular pneumocephalus 6 years before presentation. At admission, computed tomography (CT) imaging of the head showed enlargement of the lateral ventricles, a right mastoid fluid collection, and a defect of the superior wall of the right petrous bone. We performed a right temporal craniotomy for the repair of the CSF leak. Intraoperatively, it was noted that temporal lobe parenchyma herniated into the mastoid air cells through lacerated dura and a partially defective tegmen mastoideum. The leak point was successfully obliterated with a pericranial graft and reinforced by a collagen sheet and fibrin glue. There was no recurrence of otorrhea postoperatively. Conclusion: This report presents a very unique case of a patient with a CSF leak and pneumocephalus occurring on the contralateral side of a previous cranial surgery. We accurately identified the defect site with CT imaging and repaired the CSF leak by temporal craniotomy. Awareness of the mechanisms by which sCSF leaks can be caused by aberrant arachnoid granulations is imperative for neurosurgeons.

A 27-year-old female with no history of trauma, surgery, infection, or neoplastic process was evaluated for the spontaneous onset of vomiting, headache, and loss of balance. Initial studies demonstrated extensive pneumocephalus. CT revealed a lytic, expansile defect of the right petrous bone, while intrathecal contrast images demonstrated flow of CSF that implied coincidental perforation of the tympanic membrane. MR imaging demonstrated a continuity of CSF signal. The patient underwent surgery to repair the CSF leak and a dural patch was applied. No symptoms of pneumocephalus were seen after surgery and the patient's condition improved.

Introduction. Spontaneous nontraumatic pneumocephalus (PNC) and cerebrospinal fluid (CSF) leaks are both very uncommon conditions. We report a rare case of spontaneous pneumocephalus associated with CSF leak secondary to right sphenoid sinus bony defect without history of trauma.Case Description. 51-year-old Hispanic female with past medical history of hypertension and idiopathic intracranial hypertension (Pseudotumor Cerebri) presented to the emergency room complaining of headache and clear discharge from the right nostril. Physical examination was significant for right frontal sinus tenderness and clear discharge from right nostril. Computed Tomography (CT) scan of the brain showed moderate amount of extra-axial air within the right cerebral hemisphere indicative of pneumocephalus. CT scan of facial bones showed bony defect along the right sphenoid sinus with abnormal CSF collection. The patient was started on intravenous antibiotics for meningitis prophylaxis and subsequently underwent transsphenoidal repair of cerebrospinal fluid leak with abdominal fat graft. CSF rhinorrhea stopped completely after the surgery with near complete resolution of pneumocephalus before discharge.Conclusions. Early identification of pneumocephalus and surgical intervention can help decrease the morbidity and avoid possible complications. Idiopathic intracranial hypertension, although rare, can lead to CSF leak and pneumocepahlus.

Abstract Background Cerebrospinal fluid (CSF) leakage is a common complication after neurosurgical intervention. It is associated with substantial morbidity and increased healthcare costs. The current systematic review and meta-analysis aim to quantify the incidence of cerebrospinal fluid leakage in the pediatric population and identify its risk factors. Methods The authors followed the PRISMA guidelines. The Embase, PubMed, and Cochrane database were searched for studies reporting CSF leakage after intradural cranial surgery in patients up to 18 years old. Meta-analysis of incidences was performed using a generalized linear mixed model. Results Twenty-six articles were included in this systematic review. Data were retrieved of 2929 patients who underwent a total of 3034 intradural cranial surgeries. Surprisingly, only four of the included articles reported their definition of CSF leakage. The overall CSF leakage rate was 4.4% (95% CI 2.6 to 7.3%). The odds of CSF leakage were significantly greater for craniectomy as opposed to craniotomy (OR 4.7, 95% CI 1.7 to 13.4) and infratentorial as opposed to supratentorial surgery (OR 5.9, 95% CI 1.7 to 20.6). The odds of CSF leakage were significantly lower for duraplasty use versus no duraplasty (OR 0.41 95% CI 0.2 to 0.9). Conclusion The overall CSF leakage rate after intradural cranial surgery in the pediatric population is 4.4%. Risk factors are craniectomy and infratentorial surgery. Duraplasty use is negatively associated with CSF leak. We suggest defining a CSF leak as “leakage of CSF through the skin,” as an unambiguous definition is fundamental for future research.

Introduction: Pneumocephalus is mainly associated with traumatic injuries, being a rare complication but with high mortality rates; it behaves like a space-occupying lesion and increases intracranial pressure. The symptoms are not specific, but in the event of trauma it is necessary to suspect this entity to carry out a timely diagnosis and treatment, since being the product of the skull base fracture it can cause communication with the outside, and the appearance of cerebrospinal fluid (CSF) leak. Clinical Case: a 38-year-old male patient who suffers trauma from a pyrotechnic explosion near his right ear, when handling a pyrotechnic object (whistle) during the New Year, presenting severe pain, slight bleeding in the right ear, feeling faint and holocranial headache that increased in a standing position; likewise, he presents high-flow aqueous secretion (CSF) from the right ear. Brain and skull base tomography (CT) showed air in the intracranial cavity, fracture of the skull base, and the ossicles of the right middle ear. Conservative management was performed using rest and lumbar drainage, presenting a satisfactory evolution. Conclusion: Pneumocephalus is a frequent and expected complication of trauma with a skull base fracture. Its early and timely diagnosis using skull base CT is essential to define therapeutic measures. Accidents due to the misuse of pyrotechnics continue to be a relevant problem in our country. Knowing and disseminating its consequences can help raise awareness in the population. Keywords: Pneumocephalus, Skull Base, Intracranial Pressure, Cerebrospinal Fluid Leak. (Source: MeSH NLM)

Uneventful Pregnancy

Dr. Silverman: I shall present the history of an infant who was admitted to our premature nursery on May 9, 1956. This Puerto Rican male infant was born during the thirty-sixth week of an uneventful pregnancy. An antenatal serologic test for syphilis was negative. Delivery was spontaneous. Birth weight was 1070 gm. Physical examination on admission to the nursery revealed the liver to be 1 cm below the right costal margin and the spleen was firm, 1 cm below the left costal margin. Nothing else worthy of comment was noted and the infant was managed in a routine manner. The immediate newborn period was entirely uneventful, specifically neither petechiae nor unusual degree of icterus were noted. The ocular fundi were examined, as a matter of routine, during the third and fifth weeks of life and they were described as normal. During the sixth week of life, when the infant weighed 2080 gm, it was suddenly noted that the abdomen was quite distended. Examination at this time disclosed marked hepatosplenomegaly, both organs were firm. Again neither icterus nor petechiae were noted. There appeared to be some difficulty in swallowing. Roentgenograms of the chest at this time were normal and of the skull revealed intracranial calcification which was displayed in a pattern that seemed to outline dilated lateral ventricles. Lumbar puncture yielded cerebrospinal fluid which was negative except for protein of 198 mg/100 ml. The urine and cerebrospinal fluid were examined for the cells characteristic of cytomegalic inclusion disease and none were found. Funduscopic examination at this time disclosed an area of chorioretinitis in the right eye. It was presumed at this time that the infant had toxoplasmosis.

Background Intrathecal fluorescein (IF) has become a common tool for localization of cerebrospinal fluid (CSF) leak, but despite frequent use, IF lacks Food and Drug Administration approval. The diagnostic ability of high-resolution computed tomography (HRCT) has increased over several decades. Subspecialized rhinology training within otolaryngology has, similarly, allowed for dedicated skull base surgeons to become more adept at CSF leak localization. Objectives To evaluate the utility of HRCT and IF in CSF leak localization. To identify certain patient populations in which IF has added utility. To analyze the ability of fellowship-trained neuroradiologist and rhinologist to localize CSF leak sites. Methods Data were collected from a single, tertiary care academic institution. Patients admitted for CSF leak between 2003 and 2016 were included. Diagnostic yield of preoperative imaging and IF for identification of leak site was analyzed. Fellowship-trained neuroradiologist and rhinologist performed retrospective review of CT imaging and identified CSF leak sites. Results One hundred and two patients underwent CSF leak repair. Skull base defects were preoperatively localized to exact sinus on imaging report in 67% of patients. Preoperative imaging stratified by CT slice thickness of 0.625 mm identified leak site in 88.9% of cases. Blinded retrospective review by a neuroradiologist and rhinologist was able to localize the CSF leak to the correct or adjacent sinus in >80% of cases. IF was useful for intraoperative localization in 73% of cases. When preoperative imaging failed at leak site localization, IF was able to correctly identify leak site in 75% of cases. Conclusions The diagnostic yield of IF and CT imaging was equivalent, with each modality localizing leak site approximately two-thirds of the time. CT imaging with 0.625 mm slice thickness proved more efficacious in identification of skull base defects. IF demonstrated increased utility in instances where preoperative imaging has failed at leak site identification.

We describe the case of a 26-year-old man with orthostatic headache. Cerebral angiography revealed thrombosis in the sagittal sinus. Spine MRI showed cerebrospinal fluid collection at the C1–2 level. We performed blood patch and the symptoms disappeared. We report a rare case of intracranial hypotension caused by CSF leak and describe our hypothesis that SIH can change the velocity of cerebral blood flow and cause thrombosis.

A 35-year-old man with history of schizophrenia presented 3 weeks after placing a screw in his right nostril. Initial imaging showed a screw in the right ethmoid sinus with the tip penetrating the right cribriform plate. On exam, the patient was hemodynamically stable with purulent drainage in the right nasal cavity but no visible foreign body. While most nasal foreign bodies occur in children and are generally removed at the bedside, intranasal foreign bodies in adults tend to require further assessment. The foreign body in this case was concerning for skull base involvement and the patient was brought to the operating room (OR) with neurosurgery for endoscopic sinus surgery (ESS) and removal of foreign body. The screw was removed and the patient recovered with no signs of cerebrospinal fluid (CSF) leak postoperatively. Any concern for skull base or intracranial involvement should call for a full evaluation of the mechanism of injury and intervention in a controlled environment.

A 28-year-old woman presented with a one day history of high fever and partial seizures with secondary generalization. This was preceded by a three week history of headache, ataxia, and fatigue. An initial computed tomogram head scan showed a low density mass lesion in the right frontal operculum without enhancement. On the next day, a repeat scan showed a new frontopolar, expansile, low density cortical lesion (Figure 1A) suggestive of encephalitis. Cerebrospinal fluid showed a pleocytosis of 311 mononuclear white blood cell count per μL and an elevated protein of 1.57 g/L. She received intravenous acyclovir and antibiotics. She remained febrile and became mute. A magnetic resonance (MR) scan under general anesthesia on her fourth hospital day showed frontal and perisylvian lesions with restricted diffusion (Figure 1B - D and Figure 2). A right frontal brain biopsy showed meningoencephalitis and immunohistochemical staining was positive for herpes simplex virus (HSV) antigen (Figure 3). Subsequently, HSV-1 DNA was demonstrated in both cerebrospinal fluid and brain tissue with polymerase chain amplification. She improved after a course of intravenous therapy with acyclovir with residual frontal lobe signs, including marked executive dysfunction, and her speech became normal.

We present a 25-year-old female with a history of multiple intracranial cavernous malformations complaining of vertigo. Imaging is significant for increasing size of a lesion in her left cerebellar peduncle. Given the proximity to the lateral border of the cerebellar peduncle, a retrosigmoid approach was chosen. After performing a craniotomy that exposed the transverse-sigmoid sinus junction, the dura was open and reflected. The arachnoid was sharply opened and cerebrospinal fluid was aspirated to allow the cerebellum to fall away from the petrous bone. The cerebellopontine fissure was then opened to visualize the lateral wall of the cerebellar peduncle. The cavernous malformation was entered and resected.The video can be found here: http://youtu.be/P7mpVbaCiJE.
