Subdural empyema complicating a concha bullosa pyocele
The differential diagnosis includes pyocele, hematocele, epididymal cyst, epididymal cystic lymphangioma, varicocele, and rhabdomyosarcoma.
6,8) In the case reported here, color Doppler showed vessels within the septae, a finding that would not be expected in an organized pyocele or hematocele, which may otherwise have a similar sonographic appearance.
Rarely, a pyocele
, meningitis, or brain abscess may develop.
Other complications of epididymitis include infarction, abscess, and pyocele formation.
Pyocele from untreated infection or rupture of abscess typically shows internal septations and loculations on US (Figure 8).
Obstruction of this ostium by a polyp from the frontoethmoid recess, as occurred in this case, could lead to the formation of a mucocele or pyocele
with potential orbital complications.
CT was performed before biopsy, and it revealed bilateral massive conchae bullosa with evidence of a pyocele
on the left one (figure).
in the anterior intracranial fossa--case report.
Magnetic resonance imaging (MRI) can help distinguish tumors (variable thickness with heterogeneous gadolinium enhancement) from pyoceles
(content looks like fluid in the thin side with homogeneous gadolinium enhancement).
