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.

“…Controversy exists concerning the confirmation of PA in sterile lesions. Some authors consider sterile abscesses as sequelae of the aseptic necrosis of pituitary tumors [17]. The management recommended for PA is surgical drainage by the transsphenoidal approach and antibiotic treatment.…”

Pituitary abscess: a report of two cases

et al. 2007

Pituitary abscess (PA) is an infrequent disease, which consists of an infection within the sella turcica that might be life-threatening. We present here two cases of this rare entity. Case 1: A 53-year-old woman was followed for an incidentally found pituitary cyst. Six years later the cyst enlarged and transsphenoidal surgery was performed. Two years later, the patient developed sudden onset of intense headache and nausea. The MRI showed a 2 by 2.5 cm sellar and suprasellar mass, that enhanced peripherally with gadolinium contrast and became hyperintense in T2-weighted images, suggesting a new-onset cystic lesion. During transsphenoidal surgery, large amounts of purulent material were drained from the sella. The cultures were positive for Klebsiella Ozaenae. Case 2: A 63-year-old woman, 4 years after transsphenoidal resection of a GH-secreting macroadenoma, developed a new sellar 2.6 cm cystic mass. On re-operation, purulent material was drained from the sella. The lesion persisted on the MRI and visual acuity worsened so a repeat pituitary decompression was carried out 6 months later, obtaining the same pathological results. Three years later, the MRI still shows the same mass. She feels well and her physical examination and clinical history are unremarkable. These cases illustrate the difficulties in the diagnosis and management of this rare entity.

Blurred Vision Caused by Inflammation of the Optic Nerves Due to a Pituitary Abscess-Case Report-

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.
