Hypophysitis is a rare inflammatory disorder that can mimic a pituitary tumor clinically or radiologically. Furthermore, immunoglobulin G4 (IgG4)-related systemic disease is only a just recently characterized disorder. It can manifest as a systemic disease involving multiple organs, including the
OBJECTIVE
Lymphocytic hypophysitis (LH) is a rare chronic inflammatory disorder characterized by lymphocytic infiltration of the pituitary gland commonly affecting women during pregnancy or post-partum period. The pathogenesis remains uncertain, however an autoimmune process is frequently
Recent findings revealed that the clinical features of lymphocytic hypophysitis are more complicated than previously thought. It is rarely described in the first trimester of pregnancy and signs of meningeal irritation are infrequently reported. In this study, a pregnant woman in her first trimester
Sheehan's syndrome and lymphocytic hypophysitis often occur in relation to pregnancy, making their differentiation difficult. We describe a 52-yr-old woman with hypopituitarism, Hashimoto's thyroiditis and candidiasis. She was admitted to our hospital because of nausea, vomiting and constipation.
Autoimmune hypophysitis is an immune-related adverse event of immune checkpoint inhibitors. In this article, we present the case of a 58-year-old female patient who presented to the emergency room with gradually worsening nonspecific symptoms of headache, nausea, vomiting and decreased oral intake
A 32-year-old woman presented with severe headache, photophobia, fever, nausea, vomiting, and worsening vision. She had also noted several months of amenorrhea. She was febrile to 38.9 degrees C. Laboratory evaluation revealed a markedly elevated erythrocyte sedimentation rate. Lumbar puncture
Background: Hypophysitis is primary or idiopathic or secondary to another disease process. The histologic subtypes of hypophysitis are lymphocytic, granulomatous, xanthomatous, xanthogranulomatous, or IgG4-related. Granulomatous hypophysitis is the second most common form and is characterized
A case of lymphocytic hypophysitis in a patient with systemic lupus erythematosus is described. A 20-year-old woman was admitted to our hospital with generalized myalgia and facial rash in May 1998. The patient had a medical history, physical examination, and laboratory findings compatible with
Compression of the internal carotid artery (ICA) in the cavernous sinus area is a rare event and is mostly associated with pituitary adenomas and meningiomas. Other causes of ICA compression are less well known. We present a rare case of granulomatous hypophysitis causing compression Idiopathic granulomatous hypophysitis (IGH) is a rare inflammatory disease of the pituitary. There is debate in the scientific literature as to whether IGH represents a continuum of disease with lymphocytic hypophysitis or has a distinct pathogenesis. Due to the rare nature of the disease, previous
Tumor-like hypophysitis is an uncommon sellar condition that presents as inflammatory lesions on the structures of the pituitary gland. The diagnosis and management of hypophysitis poses a significant challenge, as its clinical manifestation and appearance in imaging studies are difficult to
Inflammatory lesions of the hypophysis include lymphocytic hypophysitis, pituitary abscess, and granulomatous inflammation, with or without specific infections (i.e., sarcoidosis, mycobacteria). These lesions are known to mimic pituitary neoplasms. We report the clinical and pathologic findings in
The misdiagnosis of hypopituitarism is common due to its rarity and its nonspecific clinical manifestations. Our case report highlights the importance of critical evaluation regarding hypopituitarism as a cause of recurrent hypoglycemia, hyponatremia, and gastrointestinal symptoms in A 40-year-old man with stage III melanoma arising from his left shoulder underwent wide local excision, sentinel lymph node biopsy, and lymph node dissection. Nine months after receiving adjuvant biochemotherapy with cisplatin, vinblastine, dacarbazine, interleukin-2 (IL-2), and interferon alfa as
Acute renal impairment is a relatively rare complication of anti-tumour immunotherapy. The incidence of renal toxicity due to immuno-oncological therapy is relatively low, approximately 2% in patients treated with PD-1/PD-L1 inhibitors and 4.5% with combination treatments with
