A possible and rare cause of hemiparkinsonism is mechanical compression of the basal ganglia and its connecting white matter tracts. The authors present a case of hemiparkinsonism caused by a lateral sphenoid wing meningioma, discuss the underlying pathophysiology based on tractography, and systematically review the existing literature.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>OBSERVATIONS<\/jats:title>\n                    <jats:p>A 59-year-old female was referred for a left-sided tremor of the hand, accompanied by a cogwheel rigidity of the left arm. Symptomatology appeared 1 year earlier and worsened in the previous 6 months, finally also showing involvement of the left leg. Magnetic resonance imaging (MRI) showed a space-occupying suspected meningioma originating from the right lateral sphenoid wing and compressing the ipsilateral striatum. Tractography studies contributed to elucidate the underlying pathophysiology. Resection of the meningioma could be performed without complications. At the 4-month follow-up, the patient\u2019s hemiparkinsonism had completely recovered.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>An intracranial space-occupying lesion may be a rare cause of hemiparkinsonism. In new-onset parkinsonism, especially if a secondary form is suspected, brain MRI should be performed promptly to avoid misdiagnosis and treatment. Tractography studies help understand the underlying pathophysiology. After surgical decompression of the affected structures, symptoms can recover completely.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case22398","type":"journal-article","created":{"date-parts":[[2023,2,6]],"date-time":"2023-02-06T07:35:24Z","timestamp":1675668924000},"source":"Crossref","is-referenced-by-count":1,"title":["Hemiparkinsonism caused by a lateral sphenoid wing meningioma, with tractography analysis: illustrative case"],"prefix":"10.3171","volume":"5","author":[{"given":"Attill","family":"Saemann","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefan","family":"Busch","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ethan","family":"Taub","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Birgit","family":"Westermann","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cristina","family":"Granziera","sequence":"additional","affiliation":[{"name":"Neurology, University Hospital of Basel, Basel, Switzerland; and"},{"name":"Faculty of Medicine, University of Basel, Basel, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Raphael","family":"Guzman","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Faculty of Medicine, University of Basel, Basel, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Mariani","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Faculty of Medicine, University of Basel, Basel, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jehuda","family":"Soleman","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"},{"name":"Faculty of Medicine, University of Basel, Basel, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonathan","family":"Rychen","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"8","key":"b1","series-title":"Cold Spring Harb Perspect Med","first-page":"a009258","article-title":"Parkinson\u2019s disease and parkinsonism: neuropathology","volume":"2","author":"Dickson DW","year":"2012","unstructured":"Dickson DW.
