Fig. 1A31-year-old woman with hidradenitis suppurativa. Axial
T1-weighted spin-echo MR image (TR/TE, 467/9) obtained through upper thigh
without fat saturation shows marked cutaneous thickening of medial thighs that
is of low signal intensity (arrows).
Fig. 1B31-year-old woman with hidradenitis suppurativa. Axial
T2-weighted fast spin-echo MR image (3,800/84) obtained through upper thigh
with fat saturation shows edema of subcutaneous tissues with skin thickening
of high signal intensity (arrows).
Fig. 1C31-year-old woman with hidradenitis suppurativa. Axial
T2-weighted fast spin-echo MR image (3,800/84) of labia majora obtained
through perineum with fat saturation shows ovoid area of high signal intensity
(long arrow) that is consistent with abscess and reveals skin
induration and thickening. Also, note enlarged lymph nodes (short
arrows).
Fig. 1D31-year-old woman with hidradenitis suppurativa. Axial
T1-weighted spoiled gradient-recalled echo MR image (250/3.1) obtained through
perineum with fat saturation after IV contrast administration at same level as
C also shows ovoid area of high signal intensity (long arrow)
after IV contrast administration consistent with abscess. Also, note enlarged
lymph nodes (short arrows).
Fig. 1E31-year-old woman with hidradenitis suppurativa. Axial
T1-weighted spoiled gradient-recalled echo MR image (250/3.1) of labia majora
obtained through perineum with fat saturation after IV contrast administration
shows marked enhancement of indurated and thickened skin and of subcutaneous
tissues (long arrows). Also, note enhancing enlarged lymph nodes
(short arrows).
Fig. 1F31-year-old woman with hidradenitis suppurativa. Axial
T2-weighted fast spin-echo MR image (3,800/84) obtained through mons pubis
with fat saturation shows several high-signal-intensity foci (arrows)
consistent with abscesses in cutaneous and subcutaneous tissues anterior to
symphysis pubis.
Fig. 1G31-year-old woman with hidradenitis suppurativa. Axial
T1-weighted spoiled gradient-recalled echo MR image (250/3.1) obtained through
mons pubis with fat saturation after IV contrast administration shows marked
enhancement of indurated and thickened skin and inflammatory stranding of
subcutaneous tissues (arrows).
Fig. 1H31-year-old woman with hidradenitis suppurativa. Coronal
T1-weighted spoiled gradient-recalled echo MR image (240/2.4) obtained through
mons pubis with fat saturation after IV contrast administration shows enlarged
lymph nodes (thin arrows). Also, note marked enhancement of indurated
and thickened skin and inflammatory stranding of subcutaneous tissues
(thick arrow).
Fig. 1I31-year-old woman with hidradenitis suppurativa. Coronal
T1-weighted spoiled gradient-recalled echo MR image (240/2.4) obtained with
fat saturation after IV contrast administration shows small rim-enhancing area
(thick arrow) within medial thigh that is compatible with abscess.
Also, note skin induration and thickening with inflammatory stranding of
subcutaneous tissues (thin arrows).
Fig. 1J31-year-old woman with hidradenitis suppurativa. Coronal
T1-weighted spoiled gradient-recalled echo MR image (240/2.4) obtained with
fat saturation after IV contrast administration shows normal appearance of
rectum.
