Mass Lesions

Seven cases of lymphocytic hypophysitis in women have been reported previously in association with various degrees of hypopituitarism. We report two pregnant patients who presented with mass lesions of the sella turcica, clinically mimicking pituitary adenoma. However, pathologic examination revealed extensive infiltration of the anterior pituitary by lymphocytes and plasma cells with destruction of the gland. To our knowledge, the ultrastructural features of lymphocytic hypophysitis have not been studied so far.For transmission electron microscopy, tissue from surgical specimens was fixed in glutaraldehyde, postfixed in OsO4, dehydrated and embedded in epoxy-resin. Ultrathin sections were stained with uranyl acetate and lead citrate and examined with a Philips 300 electron microscope.Electron microscopy revealed adenohypophysial cells of all types exhibiting varying degrees of injury. In the areas of most dense inflammatory cell infiltration pituitary cells contained large lysosomal bodies fusing with secretory granules (Fig. 1), as well as increased numbers of swollen mitochondria, indicating oncocytic transformation (Fig. 2).

Transsphenoidal Resection

Abstract Background Functional gonadotroph adenomas (FGAs) are rare adenomas that most commonly secrete FSH. However, solitary LH-secreting pituitary adenomas are unusual. Case presentation A 30-year-old woman with elevated LH and normal FSH presented with inability to conceive. An MRI revealed an enlarged sella turcica and an intrasellar mass. Treatment with transsphenoidal resection led to normalization of LH and estradiol, as well as successful pregnancy. And we reviewed 6 cases of LH-secreting pituitary adenomas from 1981 to 2020. Conclusions Our case is unique because of the LH-secreting pituitary adenoma without FSH hypersecretion. This case indicates that pituitary adenoma should be considered when other diseases causing infertility have been excluded.

AbstractLesions of the oculomotor nerve as the first sign of pituitary adenoma are rare. The cause of such lesions without other clinical symptoms is discussed in this study. A small cohort of 4 patients (3.1%) with oculomotor nerve palsy (third nerve palsy) as the only neurologic deficit, from 129 patients who got operated upon for pituitary adenomas, is presented. In this group (mean age: 55 years, range: 36–65 years), all patients (two women and two men) underwent surgery. In two cases, there was arrested pneumatization and thickened bone. In the remaining two cases, a macroscopically visible, very solid opaque diaphragm was present, after the removal of the tumor and thickened bone. Complete adjustment was observed in all patients within 1 week after the surgery. Two factors that seem to increase the high risk for the development of oculomotor nerve palsy are that the cavernous sinus may be the only weak structure surrounding the sella turcica when the diaphragm and bone are thickened; and the rapid development of increased pressure in this region. The increased pressure on the cavernous sinus during the anatomical variations is the primary cause for lesions on the oculomotor nerve. However, this conjecture cannot be statistically demonstrated because of the small number of cases. Future research should be conducted on larger samples to increase statistical inference and generalizability.

✓ Seven cases of pituitary abscess are presented and the relevant world literature is reviewed. An enlarged sella co-existing with bacterial meningitis, or bacterial meningitis coinciding with a known or suspected pituitary tumor should suggest the diagnosis of pituitary abscess. Visual field defects should evoke similar suspicion when present in a patient with meningitis. This reasoning enabled us to make the first reported preoperative diagnosis of pituitary abscess. Therefore, in the management of purulent meningitis, we recommend the following: first, skull films are mandatory; second, if the sella turcica is abnormal, the correct presumptive diagnosis is pituitary abscess; and third, if prompt improvement does not follow appropriate antibiotic therapy, the suspected abscess should be explored and drained via the transsphenoidal approach.

Fluid Leak

The detailed surgical procedure of the transsphenoidal surgery for pituitary abscess has scarcely been described previously because it is a very rare clinical entity. The authors reported two cases of primary pituitary abscess. In case 1, the anterior wall of the sella turcica was reconstructed with the vomer bone after irrigating the abscess cavity, but the sella was not packed by fat for fear of the persistent infection by devascularized tissues. This led to the postoperative meningocele, the cerebrospinal fluid leak, and bacterial meningitis despite the successful abscess drainage. In case 2, tight sellar packing and reconstruction of the sellar wall were performed to avoid these postoperative complications, which resulted in complete drainage and uneventful postoperative course. Although accumulation of more cases is obviously needed to establish the definitive surgical technique in pituitary abscess surgery, our experience might suggest that packing of the sella is not impeditive for postoperative sufficient drainage.
