    A single institution series of cavernomas of the brainstem
    (JOURNAL OF CLINICAL NEUROSCIENCE, 2011)
    We retrospectively analyzed a series of patients with brainstem cavernomas of the medulla, pons, or midbrain to attempt to define the natural history, indications for surgery, and outcome after surgical resection. Between 1993 and 2008, 52 patients with cavernomas of the brainstem presented to our institute and were managed either surgically or conservatively. Twenty-three patients underwent surgical excision using standard skull base approaches. Outcomes were correlated to the number of preoperative hemorrhages, location of the cavernoma, timing of surgery in relation to the hemorrhage and the preoperative neurological status. Nine patients improved after surgery, 12 deteriorated and two died. In the conservatively managed group, 15 patients had a good outcome, 11 deteriorated and one died. Multiple hemorrhages, poor preoperative neurological status and surgery during the acute phase were predictive of the surgical outcome. Excision of brainstem cavernomas should be considered in patients with symptomatic hemorrhages whose lesions approach the pial surface. Patients with minimal stable neurologic deficits without recurrent bleeds should be managed conservatively. (C) 2011 Elsevier Ltd. All rights reserved.

    Case Report: Floating fat globule within an arachnoid cyst.
    (The Indian journal of radiology & imaging, 2011)
    Intralesional floating fat globules have been reported in cystic lesions such as teratoma of the ovary and dermoid of the head and neck but not within intracranial lesions. Fat globules dispersed within the subarachnoid space are a known imaging finding of ruptured intracranial dermoid. We report a unique case of an intralesional solitary floating fat globule within a multicompartmental arachnoid cyst, with varying locations on serial imaging. We also put forward a hypothesis for the pathogenesis of fat within an arachnoid cyst. To the best of our knowledge, this is the first such report in the literature.
