The lymphocyte subsets present in the infiltrate were characterized by immunohistochemical methods to establish the contribution of different elements of the cellular immune response. [ncbi.nlm.nih.gov]

  • Swelling

    In obtaining a differential diagnosis of lymphocytic adenohypophysitis preoperatively, it is useful to note swelling of the anterior hypophyseal tissue and the existence of a posterior pituitary lobe on sagittal sections of magnetic resonance imaging [ncbi.nlm.nih.gov]

    The axons run from the supraoptic and paraventricular hypothalamic nuclei and have swellings called neurosecretory (Herring) bodies (NB) from which either oxytocin or vasopressin is released upon neural stimulation. [de.slideshare.net]

    One case showed swelling of the posterior pituitary gland. Among all patients ( n 22), an abnormally thickened infundibular stalk was found in 17 patients, and loss of T1 hyperintensity in the posterior lobe was seen in 18 patients. [e-enm.org]

    There are some reported cases presenting with swelling of the whole pituitary gland and stalk with no appreciable anterior pituitary dysfunction. [asean-endocrinejournal.org]

  • Cold Intolerance

    A 47-year-old woman complaining of cold intolerance, general weakness and amenorrhea of 10 months duration was diagnosed, by endocrine examinations, as having panhypopituitarism. [ncbi.nlm.nih.gov]

  • Unconsciousness

    An unconscious, 29-year-old woman was taken to hospital where, 28 hours after admission, she succumbed to an intractable shock. Autopsy disclosed a lymphocytic adenohypophysitis (LAH). [ncbi.nlm.nih.gov]

    Compression of the pituitary gland itself may cause hypopituitarism, and compression of the optic chiasm results in bitemporal hemianopsia. Headache is also a common symptom of pituitary tumors. [emedicine.medscape.com]

    Bitemporal hemianopsia accounts for the majority of visual symptoms, with impaired acuity and diplopia being relatively uncommon. Endocrine dysfunction has been reported in up to 80% of cases. [surgicalneurologyint.com]

  • Visual Impairment

    Repeated CT performed three months after delivery showed that the pituitary mass had undergone a spontaneous regression in size, and her visual impairment improved. [unboundmedicine.com]

    With mass effect and dural irritation, headache, and visual impairment have been reported in up to 50–70% of cases. Bitemporal hemianopsia accounts for the majority of visual symptoms, with impaired acuity and diplopia being relatively uncommon. [surgicalneurologyint.com]

  • Blurred Vision

    A 45-year-old female presented with blurred vision, headache, and abnormal thirstiness. She was not pregnant nor postpartum. She had diabetes insipidus and bitemporal hemianopsia. [ncbi.nlm.nih.gov]

  • Suggestibility

    None of the other known causes of galactorrhea was present suggesting that this may be a new addition to the differential diagnosis of galactorrhea. [ncbi.nlm.nih.gov]

    This case suggests that some patients with postpartum hypopituitarism suggestive of lymphocytic adenohypophysitis, and with pituitary mass need not have early surgical intervention but may be closely observed and treated by hormone replacement alone. [unboundmedicine.com]

  • Oligomenorrhea

    Oligomenorrhea newly appeared during the study in three patients, although no other symptoms appeared. Serum fT3 and fT4 levels were within the reference ranges, and serum TSH level and its response to TRH stimulation remained low in all patients. [ncbi.nlm.nih.gov]

Autoimmune workup did not reveal any abnormality with CRP - 1.2 mg/l (normal 7 mg/l); antinuclear antibodies ( 1:40), and antineutrophilic cytoplasmic antibodies ( 1:16), anti-TPO Ab - 4 IU/l ( 9), RA factor 4 IU/l ( 20), and anti-TTG Ab- 3.54 IU/ ml [ijem.in]

Abstract Autoimmune hypophysitis, often referred to as lymphocytic hypophysitis, is defined as an inflammatory condition of the pituitary gland of autoimmune etiology that leads to pituitary dysfunction. [scititles.com]

Conclusion: Infundibuloneurohypophysitis should be taken into account in the etiological diagnosis of hypopituitarism, particularly if it is associated with diabetes insipidus and in cases of growth hormone deficit, secondary hypogonadism, or multiple [karger.com]

It was reasonably assumed, therefore, that this disease has an auto immune etiology. [pituitaryadenomas.com]

Lymphocytic hypophysitis is a primary inflammatory disorder that typically presents during or shortly after pregnancy. [30] Although of unknown etiology, lymphocytic hypophysitis is believed to be caused by an autoimmune process. [emedicine.medscape.com]

The early observation suggested the possibility of a spectrum of progression starting with LYH and progressing to GH.[ 25 ] In contrast, other authors cited key epidemiological factors of LYH that were not found in GH including female bias, association [surgicalneurologyint.com]

Pathophysiology: The occurrence of pituitary inflammation associated with pregnancy is felt to be secondary to the involution of the pituitary gland that takes place during this time (4,7). [medschool.lsuhsc.edu]

The pathophysiologic process apparently begins as an acute inflammatory response with enlargement of the gland, as noted in 95% tissue-documented cases. [pituitaryadenomas.com]

Cortisol inhibits the release of CRH and ACTH from the hypothalamus and pituitary gland respectively, preventing further cortisol release. Cortisol is inactivated in the liver to inactive cortisone. [endocrinesurgeon.co.uk]
