✓ A 53-year-old man, with a past history of a thoracotomy 7 years previously, developed seizures. A computerized tomography scan with contrast medium revealed a peripheral ring-like lesion in the anterolateral part of the right parietal lobe. Pathological evaluation of the resected lesion demonstrated it to be a histoplasmoma. Although rare, a histoplasmoma should be included in the differential diagnosis of a ring-shaped lesion in a patient with previous pulmonary disease.

✓ A middle-aged woman, with a previous history of medically suppressed absence attacks, presented with mild changes in mental status and a skull film demonstrating several areas of mottled, granular, intracranial calcifications. These lesions, although readily visible on computerized tomography, appeared avascular during the course of cerebral angiography. At the time of surgery the masses, which were densely calcified and generally circular, demonstrated numerous areas of superficial, white, verrucous excrescences. Microscopic, pathological evaluation confirmed the diagnosis of hemangioma calcificans. The literature describing this rare entity is briefly reviewed.

✓ This 10-year-old child suffered a hemorrhage into the right parietal lobe, the result of a ruptured arteriovenous angioma. From birth, the boy had a venous angioma of the mucous membrane of the cheek, lower lip, and hypoglossal area on the right side. The coexistence of these two vascular defects is most unusual, and venous angioma in early life may suggest the presence of cerebral angioma.

✓ In this report, the authors describe a case in which the patient began to experience a supernumerary phantom arm after she received motor cortex stimulation for central pain. The patient had a history of right thalamocapsular stroke. It is speculated that the motor cortex activation triggered a response in the patient's parietal lobe, precipitating perception of the phantom limb.To the authors' knowledge this is the first reported case of its kind.

✓ This 10-year-old girl presented with a 1-month history of progressive bulbar palsy and a solitary enhancing mass originating within the floor of the fourth ventricle. Results of initial imaging studies and presentation were suggestive of neoplasia. Subtotal resection was performed and pathological examination revealed the mass to be a histiocytic lesion, with no evidence of a glioma. The patient had no other stigmata of histiocytosis and was treated with steroid medications, resulting in prolonged resolution of the lesion. This case demonstrates that for discrete brainstem lesions the differential diagnosis includes entities other than glioma for which treatment is available. Biopsy sampling should be considered when technically feasible.

✓ The authors describe a case of glioblastoma multiforme (GBM) associated with previous gamma knife radiosurgery for a cerebral arteriovenous malformation (AVM). A 14-year-old boy had undergone radiosurgery for an AVM, which was performed using a 201-source 60Co gamma knife system at another institution. The maximum and margin radiation doses used in the procedure were 40 and 20 Gy, respectively. One year after radiosurgery, the patient noticed onset of mild left hemiparesis due to radiation necrosis. Six and one-half years after radiosurgery, at the age of 20 years, the patient experienced an attack of generalized tonic—clonic seizure. Magnetic resonance (MR) imaging revealed the existence of a brain tumor in the right parietal lobe. The patient underwent an operation and the histological diagnosis of the lesion was GBM. Ten months following the operation, that is, 99 months postradiosurgery, this patient died. To the best of the authors' knowledge, this is the first reported case of a neoplasm induced by radiosurgery for an AVM and the second case in which it occurred following radiosurgery for intracranial disease.

✓ The first case of intracranial sparganosis to be reported from the United States is presented. The patient, a 27-year-old woman, complained of focal seizures involving the right lower extremity. A left parietal parasagittal craniotomy was performed, and a granuloma containing a sparganum was excised from the parietal lobe. The clinical and pathological features of sparganosis are reviewed. Only five cases of intracranial sparganosis have previously been described.

✓ The authors present the case of a previously healthy 26-year-old man who presented with cerebrospinal acanthamebic granulomas, and they review the literature on acanthamebic granulomas of the central nervous system (CNS). The appearance of the lesion on imaging studies suggested the presence of tuberculous granulomas, which are common in India, and antituberculosis treatment was started. Despite surgical excision of a granuloma located in the right temporoparietal region and an intramedullary granuloma at T7–8, the disease progressed and resulted in death. Unlike other cases, this patient was not immunocompromised, had no history of engaging in water activities, and had no ulcers on his body, leaving in question the mode of entry used by the ameba. Acanthamebic granulomas can cause severe infections in healthy patients as well as in sick ones. This disease should be considered in the differential diagnosis when treating infective granulomas of the CNS.

✓ The benefits of radiosurgery for cavernous malformations are difficult to assess because of the unclear natural history of this vascular lesion, the inability to image malformation vessels, and the lack of an imaging technique that defines “cure.” The authors selected for radiosurgery 47 patients who harbored a hemorrhagic malformation in a critical intraparenchymal location remote from a pial or ependymal surface. Of these, 44 patients had experienced at least two hemorrhages before radiosurgery. The mean patient age was 39 years; six patients had previously undergone attempted surgical removal. The malformation was located in the pons/midbrain in 24 cases, the medulla in three, the thalamus in nine, the basal ganglia in three, deep in a parietal lobe in four, and deep in a temporal lobe in four. Patients had sustained initial hemorrhages from 0.5 to 12 years prior to radiosurgery (mean 4.12 years). In these patients, who were not typical of the majority of patients with cavernous malformations, there were 109 bleeds before radiosurgery in 193 prior observation-years, for a 56.5% annual hemorrhage rate (including the first hemorrhage), or an annual rate of 32% subsequent to the first hemorrhage. The mean follow-up period after radiosurgery was 3.6 years (range 0.33–6.4 years). The proportion of patients with hemorrhage after radiosurgery was significantly reduced (p < 0.0001), as was the mean number of hemorrhages per patient (p = 0.00004). In the first 2 years after radiosurgery, there were seven bleeds in 80 observation-years (8.8% annual hemorrhage rate). In the 2- to 6-year interval after radiosurgery, the annual rate decreased to 1.1% (one bleed). After radiosurgery, 12 patients (26%) sustained neurological worsening that correlated with imaging changes. In eight patients these deficits were temporary; two underwent surgical resection and died. Two patients had new permanent deficits (4%). A significant reduction was observed in the hemorrhage rate after radiosurgery in patients who had deep hemorrhagic cavernous malformations, especially after a 2-year latency interval. This evidence provides further support to the belief that radiosurgery is an effective strategy for cavernous malformations, especially when located within the parenchyma of the brainstem or diencephalon.
