Abstract The purpose of this report is to call attention to the clinical, myelographic, and computed tomographic appearance of a very rare type of dural cyst within the lumbosacral spinal canal. We report this condition in three unrelated boys who presented with symptoms of cauda equina compression. Our experience suggests that these cysts are congenital in origin. Anatomically, the cyst wall consisted of a dura-like layer without arachnoid. There was a small ventral defect allowing incomplete communication with the compressed subarachnoid space. Cerebrospinal fluid-like fluid accumulated within the interdural cyst as a result of this communication. Treatment consisted of obliteration of the point of entry between cyst and subarachnoid space in all cases and partial cyst wall excision in one case. After operation, the two patients who had presented with long-standing sphincter disturbance had partial improvement in function and the child with a pain syndrome was completely relieved of symptoms.

Abstract Most reports regarding synovial cysts of the spinal canal have been presentations identifying an unusual pathological entity that is to be included in the differential diagnosis of cauda equina compression syndromes. Most of the 26 cases reported represent isolated examples of this pathological process. We present five cases of lumbar synovial cysts encountered in our practice in the past 8 years. Patients with lumbar synovial cysts do not demonstrate any predictable clinical picture. They may present with a unilateral sciatica or neurogenic claudication. Lumbar extension is usually restricted, whereas flexion is full. Mechanical signs of nerve root entrapment or lumbosacral plexus irritation are unimpressive. Neurological deficits are usually mild, if present. Radiological findings include degenerative spondylosis, spondylolisthesis, and a rounded posterolateral extradural mass of low attenuation value adjacent to a facet shown on computed tomographic scan. The etiology of lumbar synovial cysts is not known. Histological findings of myxoid degeneration, microcystic change, calcification, and hemosiderin deposits suggest that chronic microtrauma with occasional focal hemorrhage may play a major role in the etiology of the cysts. With resection of the cyst, the postoperative course is usually uneventful. Recurrences have not yet been encountered in our patients.

✓ An elderly man presented with signs of normotensive hydrocephalus. Elevated protein content in the spinal fluid led to the diagnosis of an “asymptomatic” cauda equina neurilemoma and its removal. Within 6 weeks the patient's mental status had dramatically improved. Chronic transudation of plasma proteins including fibrinogen into the subarachnoid space had probably impeded spinal fluid reabsorption. It is suggested that the leakage of fibrinogen into the cerebrospinal fluid may be the cause of hydrocephalus in other clinical settings in which there is an elevation of the spinal fluid protein.

Do So

Lymph from the jugular lymph trunks of anesthetized rabbits has been continuously collected and radioiodinated albumin (RISA) therein estimated after microinjection of 1 microliter of 131I-albumin into the caudate nucleus, after single intraventricular injections, and during intraventricular infusions. Comparison of lymph at 7 and 25 h after intracerebral microinjection with efflux of radioactivity from whole brain suggests that about 50% of cleared radioactivity goes through lymph. Concentrations, normalized to cerebrospinal fluid (CSF), were much higher in lymph and retropharyngeal nodes after brain injection than after CSF injection or infusion. Also after brain injection, lymph and nodes contained more activity on injected side in contrast to lack of laterality after CSF administration. Calculation suggests that less than 30% of RISA cleared from brain can do so via a pool of well-mixed CSF. Analysis of tissues is compatible with much RISA draining by bulk flow via cerebral perivascular spaces plus passage from subarachnoid space of olfactory lobes into submucous spaces of nose and thus to lymph.

Abstract OBJECTIVE AND IMPORTANCE Penetrating injuries of the cranium and spine are frequent to the civilian neurosurgical practice. Although a variety of unusual objects have been reported, to our knowledge, there has never been a craniocerebral or spinal injury caused by a fish. An unusual case of transoral penetration of the foramen magnum by a billed fish is described. The history, radiographic studies, and treatment are presented. CLINICAL PRESENTATION A fisherman struck by a jumping fish initially presented with severe neck pain and stiffness, bleeding from the mouth, and a laceration in the right posterior pharynx. A computed tomographic scan of the cervical spine revealed a wedge-shaped, hyperdense object extending from the posterior pharynx into the spinal canal between the atlas and the occiput. Because of the time factor involved, the fisherman was brought directly to surgery for transoral removal of the object. INTERVENTION The patient was placed under general anesthesia, and with a tonsillar retractor, a kipner, and hand-held retractors, the object was visualized and identified as a fish bill. Further dissection above the anterior aspect of the atlas permitted removal of the object by means of a grabber from an arthroscopic set. No expression of cerebrospinal fluid was noted, and a Penrose drain was placed. CONCLUSION The patient was treated under the assumption that penetrating foreign objects in continuity with the cerebrospinal fluid space and the outside environment should be removed as soon as possible. The patient was provided appropriate antibiotics to treat potential infection of normal pharyngeal flora and organisms unique to the marine environment. The patient recovered and did not experience any residual neurological deficit.

Abstract Background Cerebrospinal fluid (CSF) abdominal pseudocyst (APC) is an uncommon complication following ventriculoperitoneal (VP) shunt. Aim To study the clinical features and management of this entity. The authors present their experience with cases of CSF pseudocyst in children. Materials and Methods Retrospective analysis of four cases diagnosed to have APC following VP shunt between 2005 and 2015. Results Clinical presentation was with progressive abdominal distension, highlights of intestinal obstruction, and signs of raised intracranial pressure (ICP). Diagnosis is readily made with ultrasonography and computed tomographic (CT) scan of the abdomen. The duration between insertion of the shunt and the presentation ranged from 4.11 to 12 years. In three patients, the cyst was unilocular and of varying size. The fourth one had a multilocular cyst. In three patients, the treatment involved was surgical removal of the catheter with excision of the pseudocyst wall and placement of a new catheter intraperitoneally in a different quadrant. Ultrasound-guided aspiration of the cyst and relocation of the distal end was done in one patient. Conclusion Initial suspicion with appropriate investigation and early treatment can avert morbidity and mortality.
