A Rare Case of Pericallosal Lipoma Associated with Bilaterally Symmetrical Lateral Ventricular Choroid Plexus Lipomas without Corpus Callosal Anomalies
A 58-year-old Arab man presented to our hospital with a 12-month history of recurrent headache. Clinical and neurological examinations were unremarkable. Radiological evaluation included computed tomography (CT) and Magnetic resonance imaging (MRI) scanning.\nThe CT and MRI images revealed a PCLp cephalad to the entire antero-posterior extent of the corpus callosum; continuing as bilaterally symmetrical lateral ventricular CPLps [Figures –]. The PCLp continued through the choroidal fissure as bilaterally symmetrical lateral ventricular CPLps [Figures and ]. Peripheral calcifications were noted within the PCLp [], and the corpus callosum was unremarkable []. The fat appeared more hypodense than CSF on CT scans []. PCLp measured approximately 11.2 × 2.1 cm. CPLps measured approximately 1.3 cm in maximum diameter. Discrete areas of fatty tissue were noted in the subarachnoid space along the anterior interhemispheric fissure [] and also in the medial sulcus of the right frontal lobe []. Incidentally, unusually thick dural calcifications and cavum septum pellucidum were also noted with bilateral supraventricular white matter ischemic lesions. No other central nervous system abnormalities were noted. Sagittal unenhanced T1 weighted MRI scans of a normal brain with superimposed black shading (black arrows) show morphological features that classify PCLps into anterior [] and posterior [] groups and is compared to features seen in our case [].
