✓ The authors present a case of an ossified lipoma located at the tuber cinereum. Intracranial osteolipomas are rare lesions that occur in the region of the tuber cinereum. Almost all reported cases have been incidental autopsy findings. This report, however, involves a young girl who presented with an ovarian cyst and signs of precocious puberty, in whom a typical osteolipoma was surgically removed. This is the first case of hypothalamic osteolipoma presenting with endocrinological disturbances that has been published to date.

✓ The authors report two cases of treatment by intraarterial papaverine of cerebral vasospasm complicating the resection of an arteriovenous malformation (AVM). Both cases had successful reversal of vasospasm documented on angiography. In the first case sustained neurological improvement occurred, resulting in a normal outcome by the time of discharge. In the second case, neurological deterioration occurred with the development of cerebral edema. This complication was thought to be due to normal perfusion pressure breakthrough, on the basis of angiographic arterial vasodilation and increased cerebral blood flow. These two cases illustrate an unusual complication of surgery for AVMs and demonstrate that vasospasm (along with intracranial hemorrhage, venous occlusion, and normal perfusion pressure breakthrough) should be considered in the differential diagnosis of delayed neurological deterioration following resection of these lesions. Although intraarterial papaverine may be successful in dilating spastic arteries, it may also result in pathologically high flows following AVM resection. However, this complication has not been seen in our experience of treating aneurysmal subarachnoid hemorrhage by this technique.

✓ Mutism is defined as a state in which a patient is conscious but unwilling or unable to speak. It has been reported to occur in association with a multitude of conditions, including trauma, epilepsy, tumors, stroke, psychoses, and brain surgery. The cases of two patients who became mute in the immediate postoperative period are presented. The first patient developed mutism following removal of a parasagittal meningioma, and the second following removal of a posterior fossa medulloblastoma. It is believed that transient injury may have occurred to the supplementary motor cortex in the first case and to the dentate nuclei in the second case. It is interesting that these two areas are connected via pathways involving the ventrolateral nucleus of the thalamus, and that lesions of this thalamic nucleus can also lead to mutism. It therefore appears plausible that interruption of these pathways may be involved in the pathogenesis of mutism. Although mutism is an infrequent complication of brain surgery, neurosurgeons should be aware that it may occur following removal of lesions in these areas and that it is generally a transient condition.

✓ Spinal subdural hematomas (SDHs) are a rare cause of cord compression and typically occur in the setting of spinal instrumentation or coagulopathy. The authors report the first case of a spontaneous spinal SDH occurring in conjunction with low-molecular-weight heparin use in a patient with a history of spinal radiotherapy.

✓ Although precocious puberty is common in boys with human chorionic gonadotropin (hCG)-secreting brain tumors, it is extremely rare in girls. The authors describe a 6-year-old girl with an hCG-secreting suprasellar immature teratoma who presented with diabetes insipidus, increased intracranial pressure, and precocious puberty. On admission, breast budding was observed. The serum hCG level was 1230 mIU/ml. Both luteinizing hormone (LH) and follicle-stimulating hormone (FSH) remained below detectable levels, even after gonadotropin-releasing hormone stimulation. Serum estrogen and androgen were moderately elevated. After chemotherapy, breast budding disappeared with normalization of serum hCG. It has been believed that hCG does not produce precocious puberty in girls in the absence of FSH, and this has been used as an explanation for the rarity of precocious puberty in girls with hCG-secreting brain tumors. However, it has also been reported that hCG has not only LH activity but also intrinsic, although weak, FSH-like activity. In the present case, this FSH-like activity was considered to have played a role in the development of precocious puberty. It is speculated that a very high level of serum hCG can produce precocious puberty in girls. The rarity of intracranial germ-cell tumors with a high potential of hCG secretion may be one of the reasons why hCG-induced precocious puberty is uncommon in girls.

✓ The authors report a case of infra- and supratentorial intracerebral hemorrhage complicating the postoperative course of a patient who had undergone surgical removal of a cervical schwannoma with an hourglass configuration. To their knowledge, this is the first case in which this neurosurgical procedure was followed by such a complication. Possible mechanisms are discussed; however, pathological events leading to this complication are unclear. The development of new neurological deficits not attributable to the surgical procedure should suggest this possibility.

✓ A case of a cavernous hemangioma located within Meckel's cave and involving the gasserian ganglion is described in a patient presenting with facial pain and a trigeminal nerve deficit. Although these lesions have been reported to occur in the middle fossa, this is believed to be the first case of such a vascular malformation arising solely from within Meckel's cave.

✓ Lymphangiomas, benign hamartomatous lesions involving lymphatic tissue, result from a failure of lymphatic channels to communicate with the venous system or normal lymphatic channels. The authors describe a case in which a lymphangioma arising within the ulnar nerve developed after trauma to the same area. This is the second reported case of a lymphangioma that originated from a peripheral nerve and the first case in which the lesion was associated with trauma. The authors propose that a lymphangioma involving the peripheral nerve may be the result of trauma.

✓ Two cases of carotid-cavernous fistulas were successfully treated by standard interventional radiology techniques after otherwise inaccessible vessels were surgically exposed. In the first case, an internal carotid artery (ICA), which had previously been ligated as part of an attempted surgical “entrapment” procedure, was recanalized to permit passage of a detachable balloon catheter to the fistula, resulting in its obliteration. In the second case, an enlarged superior ophthalmic vein was exposed and isolated to facilitate retrograde catheterization of the cavernous sinus and obliteration of a dural fistula between the ICA and the cavernous sinus by steel Gianturco coils. The methods and complications of both procedures are discussed.

✓ A case of lymphomatoid granulomatosis with multiple intracranial lesions is reported. Important aspects of this vasculitis are discussed, including its propensity for lymphomatous transformation, its similarity to Wegener's granulomatosis, its predilection for certain sites, and its resistance to treatment. A correlation is described between the computerized tomography scan and the autopsy findings.

✓ A case of intrasellar teratoma with a germinal structure in a 10-year-old girl is described. A few months after intracranial surgery the tumor differentiated into a choriocarcinoma and finally spread to multiple cerebral, pulmonary, and renal metastases. In the course of choriocarcinomatous evolution, very high urinary levels of luteinizing gonadotropin (HCG) developed, but there was no clinical or anatomical evidence of precocious puberty.
