Object. The cisternal portion of the trochlear nerve (fourth cranial nerve) can easily be injured during intracranial surgical operations. To help minimize the chance of such injury by promoting a thorough understanding of the anatomy of this nerve and its relationships to surrounding structures, the authors present this anatomical study.

Methods. In this study, in which 12 cadaveric heads (24 sides) were used, the authors describe exact distances between the trochlear nerve and various surrounding structures. Also described are relatively safe areas in which to manipulate or enter the tentorium, and these are referenced to external landmarks.

Conclusions. This information will prove useful in planning and executing surgical procedures in and around the free edge of the tentorium cerebelli.

✓Self-mutilation after deafferentation injuries has rarely been reported in humans. The authors report on a 16-year-old girl who was born with a myelomeningocele. In adolescence it was noted that concurrent with her spinal cord becoming symptomatically tethered she began to self-mutilate her digits. A rare manifestation of the tethered spinal cord may be dysesthesias that led to self-mutilation.

✓The authors present the case of a child diagnosed as having Beckwith—Wiedemann syndrome and Chiari I malformation. Hemihypertrophy is associated with Beckwith—Wiedemann syndrome and has been described in conjunction with Chiari I malformation. The authors hypothesize that the hemihypertrophy that may involve the skull base and Chiari I malformation found in their patient are not spurious findings but are pathologically related, perhaps by slight dysmorphologies of the posterior cranial fossa.

✓The authors present a case of an adolescent with achondroplasia and symptoms of neurogenic claudication who, interestingly, also presented with intermittent priapism. Both the neurogenic claudication and priapism were relieved following a thoracolumbar laminectomy. To our knowledge, this is the first report of a dwarf with thoracolumbar spinal canal stenosis presenting with priapism.

OBJECT

Additional distal sites for placement of CSF diversionary shunts may be necessary in some patients. The present study aimed to investigate the marrow space of the ilium as a potential receptacle for CSF in patients with hydrocephalus.

METHODS

Cannulation of the marrow space of the ilium was performed in 5 fresh human cadavers less than 4 hours from time of death. Tap water was infused via a metal trocar for approximately 60 minutes.

RESULTS

A total of 30 L of water was easily injected into all cadaveric specimens without overflow from the infusion site or noticeable edema of the body. Upon inspection of the thoracic and abdominal cavities, no fluid accumulation was identified, ensuring that all infused fluid had gone into the vascular system.

CONCLUSIONS

Based on this cadaveric study, the ilium appears to be an ideal location for placement of the distal end of a CSF diversionary shunt when other anatomical receptacles are not an option. In vivo human studies are now required to verify these findings.
