  Deeply embedded and at distances of several kiloparsecs, massive young
stellar objects (MYSOs) present numerous challenges for observation and study.
In this work, we present spatially-resolved observations of one MYSO, AFGL
4176, together with survey and literature data, ranging from interferometric
observations with VLTI/MIDI in the mid-infrared, to single-dish Herschel
measurements in the far-infrared, and sub-millimeter data from APEX. We
consider this spatially-resolved, multi-wavelength data set in terms of both
radiative transfer and geometric models. We find that the observations are well
described by one-dimensional models overall, but there are also substantial
deviations from spherical symmetry at scales of tens to hundreds of
astronomical units, which are revealed by the mid-infrared interferometric
measurements. We use a multiple-component, geometric modeling approach to
explain the mid-infrared emission on scales of tens to hundreds of astronomical
units, and find the MIDI measurements are well described by a model consisting
of a one-dimensional Gaussian halo and an inclined (\theta=60 deg)
circumstellar disk extending out to several hundred astronomical units along a
position angle of 160 deg. Finally, we compare our results both with previous
models of this source, and with those of other MYSOs, and discuss the present
situation with mid-infrared interferometric observations of massive stars.
