58-year-old man with a 12-month history of recurrent headaches diagnosed with PCLp associated with bilaterally symmetrical lateral ventricular CPLps without corpus callosal anomalies. Axial unenhanced CT scan of the head shows midline PCLp (white arrows) and left lateral ventricular CPLp (black arrow). The fat appears more hypodense than CSF.

The 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 1-4]. The fat appeared more hypodense than CSF on CT scans [Figure 1].
58-year-old man with a 12-month history of recurrent headaches diagnosed with PCLp associated with bilaterally symmetrical lateral ventricular CPLps without corpus callosal anomalies. (a and b) Axial unenhanced CT scans of the head show PCLp with peripheral calcifications (white arrows) and PCLp continuing as bilaterally symmetrical CPLps (black arrows).

The 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 1-4]. PCLp continued through the choroidal fissure as bilaterally symmetrical lateral ventricular CPLps [Figures 2 and 4]. Peripheral calcifications were noted within the PCLp [Figure 2], and the corpus callosum was unremarkable [Figure 3].
58-year-old man with a 12-month history of recurrent headaches diagnosed with PCLp associated with bilaterally symmetrical lateral ventricular CPLps without corpus callosal anomalies. Sagittal unenhanced FLAIR MRI scan shows PCLp (white arrows) and discrete areas of fatty tissue around the anterior interhemispheric fissure (black arrow). Also, evident is normal corpus callosum.

The 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 1-4]. PCLp continued through the choroidal fissure as bilaterally symmetrical lateral ventricular CPLps [Figures 2 and 4]. Peripheral calcifications were noted within the PCLp [Figure 2], and the corpus callosum was unremarkable [Figure 3]. Discrete areas of fatty tissue were noted in the subarachnoid space along the anterior interhemispheric fissure [Figure 3] and also in the medial sulcus of the right frontal lobe [Figure 5].
58-year-old man with a 12-month history of recurrent headaches diagnosed with PCLp associated with bilaterally symmetrical lateral ventricular CPLps without corpus callosal anomalies. (a and b) Coronal unenhanced T1 weighted MRI scans show PCLp (black arrows) continuing as bilaterally symmetrical lateral ventricular CPLps (white arrows).

Axial unenhanced T1 weighted MRI scan shows PCLp (white arrow) and bilaterally symmetrical lateral ventricular CPLps (black arrows). Also note discrete areas of fatty tissue in the medial sulcus of the right frontal lobe (dashed arrow).

58-year-old gentleman complaining of recurrent headaches since twelve months diagnosed with PCLp associated with bilaterally symmetrical lateral ventricular CPLps without corpus callosal anomalies. (a, b and c) Sagittal unenhanced T1 weighted MRI scans of a normal brain with superimposed black shading (black arrows) show morphological classification of PCLps (a: Anterior and b: Posterior) and c: Appearance as in our case.

Sagittal unenhanced T1 weighted MRI scans of a normal brain with superimposed black shading (black arrows) show morphological features that classify PCLps into anterior [Figure 6a] and posterior [Figure 6b] groups and is compared to features seen in our case [Figure 6c].
