This is a rare case of metastatic small cell lung cancer with initial clinical presentation of bitemporal hemianopsia related to pituitary metastasis.
Physical examination demonstrated bitemporal hemianopsia; the neurological examination was otherwise unremarkable.
A 42-year-old man presented with
bitemporal hemianopsia and decreased visual acuity.
A 44-year-old woman presented with dizziness, headache, and progressive
bitemporal hemianopsia for about 1 month.
The most common visual field disturbance is
bitemporal hemianopsia, and contiguous spread of the tumor to the adjacent cavernous sinus most commonly produces cranial nerve III and IV dysfunction (1).
Bitemporal hemianopsia and superior temporal visual field defect are found most frequently.
He could only finger count in the right eye and had an additional
bitemporal hemianopsia on visual field testing.
Most of the patients with LHON reported in the literature had central or centrocecal scotoma, [6, 22]; however, VF defects mimicking
bitemporal hemianopsia have also been described in LHON patients [23].
Neuro-ophthalmological evaluation revealed that the patient had slight
bitemporal hemianopsia. Hormone levels and biomarkers of gonioma were with normal ranges.
