“…1,11,31) MR imaging with gadolinium shows pituitary abscess with thin and smooth rim enhancement. 9,10,15,17) Occasionally, MR imaging demonstrates surrounding brain damage with evidence of encephalitis and meningeal enhancement. 2,5,15,29) The typical pituitary abscess has the same or a slightly lower signal intensity than the brain on T 1 -weighted imaging, and this could be mistaken for a solid mass or a pituitary adenoma.…”

“…Preoperative diagnosis of pituitary abscess is quite difficult and is usually based on an infectious episode or other abnormal radiological findings in addition to the pituitary cystic lesion. 9,12,20,22) Here we report a case of pituitary abscess that showed homogeneous high accumulation of thallium-201 ( 201 Tl) even though the lesion was a cyst, which allowed differentiation of the pituitary abscess from pituitary adenomas with 201 Tl single photon emission computed tomography (SPECT).…”

A 32-year-old female presented with a rare case of pituitary abscess manifesting as homonymous hemianopsia. Serum prolactin level was slightly high (40.8 ng/ml). Magnetic resonance (MR) imaging showed the content of the lesion as homogeneously isointense on the T 1 -weighted images and hyperintense on the T 2 -weighted images. The capsule of the lesion, which appeared thin and smooth, was enhanced by gadolinium. Dural enhancement around the sella turcica was also recognized. Thallium-201 single photon emission computed tomography ( 201 Tl SPECT) showed homogeneous high accumulation in the pituitary region on both the early and delayed images. The lesion was treated via a transnasaltranssphenoidal approach. The cystic lesion contained pus and the capsule consisted of normal pituitary gland with inflammatory changes. The patient was treated with antibiotics for 3 weeks and the pituitary abscess was cured completely. Pituitary abscess can be differentiated from pituitary adenoma as lesion with a homogeneous high uptake on 201 Tl SPECT on both the early and delayed images, and no enhancement of the central portion on MR images.

“…Pre-CT scan era, Donimgue and Wilson reviewed 29 patients, with 28% mortality, and this rate increased to 45% when meningitis was involved (2). The recommended management of pituitary abscess is surgical drainage by the transsphenoidal approach followed by antibiotic treatment (3)(4)(5). Furthermore, the standard empiric treatment of brain abscess is based on parenteral administration of cephalosporins or carbapenems.…”

Successful Treatment of Pituitary Abscess with Oral Administration of Sparfloxacin

Pituitary abscess is a rare infection and it is difficult to make the correct diagnosis. It is usually treated by a combination of surgical drainage and intravenous administration of antibiotics. We describe a 74-year-old woman with recurrent meningo-encephalitis due to pituitary abscess. The abscess increased in size in spite of the intravenous administration of panipenem/betamipron (PAPM/BP), clindamycin (CLDM) and chloramphenicol (CP). Finally she was successfully treated with oral administration of sparfloxacin (SPFX) without operation.

A 48-year-old woman was admitted to our institution complaining of headache and a 2-month history of blurred vision and increased urinary volume. T 1 -weighted magnetic resonance (MR) imaging with gadolinium showed a ring-enhanced mass lesion in the pituitary. Fluid-attenuated inversion recovery MR imaging showed high-intensity lesions in the optic nerves, hypothalamus, and thalamus. The histological diagnosis was pituitary abscess. The blurred vision was caused by inflammation, but not compression, of the optic nerves due to the pituitary abscess outside the hypophysis.
