Occipital Post-Traumatic Intradiploic Arachnoid Cyst Converted to Pseudomeningocele after Re-Trauma: A Rare Complication of Rare Pathology

Abstract Intradiploic arachnoid cysts have scarcely been reported in the literature, most reported cases being secondary to trauma. Nontraumatic arachnoid cysts are quite rare and have been reported mostly in adults. Here, we report the case of a 16-year-old male presenting with a slowly growing mass in the occipital region and intermittent headaches. On the basis of the findings of X-rays, computed tomography scans, and magnetic resonance imaging scans of the head, the mass was diagnosed as a giant intradiploic arachnoid cyst.

Thoracic Spinal

Abstract Arachnoid cysts of the spinal canal are relatively common lesions that may be either intra- or extradural. These cysts are usually asymptomatic but may produce symptoms by compressing the spinal cord or nerve roots. We report a case in which an intradural thoracic arachnoid cyst became symptomatic after a routine decompressive lumbar laminectomy for spinal stenosis. Myelography revealed no abnormality, although magnetic resonance imaging and computed tomography after myelography demonstrated a mass within the posterior aspect of the thoracic spinal canal associated with anterior displacement and compression of the spinal cord. A change in the flow dynamics of the cerebrospinal fluid probably allowed the development of spinal cord compression due to one of the following: expansion of the cyst, decreased cerebrospinal fluid buffer between the cord and the cyst, or epidural venous engorgement. A concomitant and more cephalad lesion such as an arachnoid cyst should be considered when myelopathic complications arise after lumbar surgery. Magnetic resonance imaging and computed tomography after myelography are useful to demonstrate the additional pathological processes.

Post Traumatic

AbstractOver the past few decades, it has been recognized that traumatic brain injury (TBI) may result in various movement disorders. However, moderate or mild TBI only rarely causes persistent post-traumatic movement disorders. In the present report, we describe a case of secondary tremor due to a mild head injury with a transitory loss of consciousness. A 26-year-old man developed an isolated rest tremor of the hands and legs without other neurologic signs. The interval between the head trauma and the onset of the symptoms was 4 months. Neuroimaging studies reveled gliosis in the lentiform nucleus. Haloperidol administration resulted in tremor reduction. A rest tremor, similar to essential tremor, can be a rare complication of head trauma. Haloperidol may be an effective and safe treatment modality for post-traumatic tremor. Further studies are needed to clarify the optimal drug for the treatment of post-traumatic tremor.
