Enlarged cerebrospinal fluid spaces in infants with subdural hematomas.

Computed tomography in 16 infants with subdural hematomas showed enlarged basal cisterns, a wide interhemispheric fissure, prominent cortical sulci, and varying degrees of ventricular enlargement. Radionuclide cisternography in eight of the 16 patients showed findings consistent with enlargement of the subarachnoid space rather than those of communicating hydrocephalus. Clinical findings and brief follow-up showed no convincing evidence for cerebral atrophy in 13 patients. These findings suggest that the enlarged subarachnoid space, which is encountered in some infants and may be a developmental variant, predisposes such infants to subdural hematomas.

Terson's syndrome--significance of ocular findings.

Ocular findings of three patients with Terson's syndrome are presented. Two patients had a ruptured intracranial aneurysm, and one had a subdural hematoma. Ocular findings included retinal, preretinal, and vitreous hemorrhages. Vitreous hemorrhage may be delayed in onset and may require vitrectomy if persistent. The eye findings are characteristic but not pathognomonic of this syndrome. The authors emphasize the diagnostic and prognostic importance of ocular findings in patients with spontaneous intracranial hemorrhages. Some of the primary theories of the syndrome are reviewed.

[Clinical study on intracranial air in the severe head injury].

Intracranial air tends to be neglected in severe head injury, because other lesions are more life threatening. We retrospectively studied patients of severe head injury with pneumocephalus. We studied 250 patients' (Glasgow Coma Scale score < or = 8 on admission) computed tomography (CT) scans and found 77 patients with pneumocephalus. These patients' medical records and neuroimagings were studied. The air was most frequently located in the subarachnoid spaces followed by subdural and epidural spaces. Intraparenchymal and intraventricular location were rare. Sphenoid or petrous bone fracture was common. In the cases with petrous or paranasal sinus bone fracture, opacification of these structures were statistically significant. In conclusion, pneumocephalus is common in the severe head injury and most frequently located in the subarachnoid spaces, however, the precise location of air is unclear in many cases. Bone CT scan is useful and opacification of air containing structures suggests the possibility of skull base fractures.

Subdural anesthesia as a complication of an interscalene brachial plexus block. Case report.

BACKGROUND AND OBJECTIVES: Interscalene brachial plexus block is performed in the groove between the anterior and middle scalene muscles at the level of C6, just over the transverse process. Injection occurs within 1-2 cm of the dural sleeve and could be misdirected into the epidural, subdural, or subarachnoid spaces. METHODS: Interscalene block was performed by elicitation of paresthesia with 40 mL 1.4% mepivacaine, 1/200,000 epinephrine. RESULTS: Initially, complete interscalene block was achieved that evolved into apnea, high motor, and sensory block; requiring induction of general anesthesia. CONCLUSIONS: The case represents a partial injection of local anesthetic intended for the interscalene brachial plexus into the subdural space. The diagnosis is based on the normal evolution of the block into full motor and sensory anesthesia of the ipsilateral brachial plexus that evolved into a patchy, sensory, and motor block involving many dermatomes outside the brachial plexus, with minimal sympathetic block, and evidence of a normal interscalene block on emergence from general anesthesia. Subdural injection must be considered when unusual motor and sensory block occurs after interscalene block, especially after a time interval too long for epidural or subarachnoid injection, or with minimal evidence of sympathetic block, after suspected high central block injection.

Imaging characteristics of the subdural evacuating port system, a new bedside therapy for subacute/chronic subdural hematoma.

The Subdural Evacuating Port System is a new device intended to simplify the treatment of subacute/chronic subdural hematomas. The appearance of the winged canula positioned with its tip in the diploic space overlying the subdural space should allow the radiologist to identify it correctly. Its radiographic features are described here to help the radiologist comment on appropriate placement, and avoid mistaking it for a misplaced subdural drain.
