    III-defined focal low attenuation in the posterior internal capsule: a normal CT finding (1996)

    Notes: Abstract Although many pathological changes in the internal capsule may lead to neurological deficits, we often encounter ill-defined focal low attenuation in the posterior limb of the internal capsule (PIC) on CT in patients with no neurological disturbance. Brain CT studies of 141 patients without neurological deficites were reviewed to investigate the position of the focal low attenuation by analysis of a profile density curve. Nine patients with lacunar infarcts only within the posterior internal capsule were also studied. The focal low attenuation areas were ill-defined and bilaterally symmetrical, without mass effect. They were seen consistently within the posterior limb of the posterior internal capsule. Correlation between the distribution of these foci and the position of lacunar infarcts in the posterior internal capsule in nine patients with neurological deficits suggests that they may be related to the corticospinal tract.

    Ultrastructural findings of the macula utriculi in a case of a petrous apex cholesteatoma: a comparison with findings in a patient with an acoustic neuroma (1997)
    Springer
    European archives of oto-rhino-laryngology and head & neck 254 (1997), S. 255-258

    Notes: Abstract The morphological characteristics of the vestibular sensory cells of the macula utriculi obtained during surgery in a patient with a petrous apex cholesteatoma were examined using scanning and transmission electron microscopy. Findings were compared to cells studied in a patient with acoustic neuroma. Scanning electron microscopy showed that compared to the apparently normal cells in the acoustic neuroma case, most sensory cells in the cholesteatoma case had large cuticular plates, irregular locations of cilia and no clear polarizations. Supporting cells showed profuse short microvilli on the whole surface. With transmission electron photomicrographs, type I hair cells were not seen and certain morphological changes were observed in type-1I-like cells and supporting cells. We presume that the degenerative changes in the vestibular epithelia were due to circulatory disturbances and/or direct pressure applied to the vestibular nerve at the internal auditory canal, with subsequent involvement of the macula utriculi.
