Abstract Objectives We present a patient with a prolactin-secreting adenoma with extensive secondary, noninfectious, xanthogranulomatous changes due to remote intratumoral bleeding and provide a literature review of xanthogranulomas (XGs) of the sellar region with emphasis on prolactinomas with xanthogranulomatous features. Design Case report, with PubMed search of cases of sellar XG, focusing on neuroimaging and surgical approach. Results A 35-year-old male was found to have a large sellar/suprasellar calcified/cystic mass. Endoscopic transsphenoidal approach for extradural resection was performed and diagnosis made. Review generated 31 patients with the diagnosis of sellar XG. In a minority (6 patients), the underlying lesion for the XG was a pituitary adenoma. Headache was the most common presenting symptom and panhypopituitarism the most common endocrinological abnormality. Examples of hyperprolactinemia associated with sellar XG are also uncommon and due to stalk effect. Neuroimaging of XG on T1-weighted magnetic resonance imaging (MRIs) showed 18 cases (56.3%) were hyperintense, 1 case (3.13%) was isointense, 4 (12.5%) had mixed-signal intensity, and 2 (6.25%) were hypointense. On T2-weighted MRIs, five lesions (15.6%) were hyperintense, three (9.38%) were isointense, nine (28.1%) were heterogeneous, and nine (28.1%) were hypointense. Only one case (3.1%) had calcifications on computed tomography scan similar to ours. In 14 cases (43.7%), the lesions enhanced with contrast administration on MRI. Conclusion Prolactinomas with secondary xanthogranulomatous change represent a rare cause of XG of the sella. With no radiological or clinical signs specific for XG of the sellar region, preoperative diagnosis can be challenging, if not impossible.

Abstract Gallbladder hernia through the foramen of Winslow is an uncommon condition and gallbladder hernia combined with volvulus is even rarer. A 70-year-old patient was hospitalized with the clinical signs of pain in the right hypochondriac region associated with fever. The computed tomography scan images showed some signs of gallbladder herniation through the foramen of Winslow. We decided to remove the gallbladder and found the gallbladder infundibulum twisted and necrotic. This was the first case of a male patient who suffered from gallbladder herniation with volvulus after three cases of female patients reported in the literature.

Transmission Computed Tomography

This case report describes a 38-year-old male who was hospitalized for further clarification of clinically mild hyperthyroidism. His increased total hormone levels, the elevated free thyroid hormones and the elevated basal TSH with blunted response to TRH strongly suggested a pituitary adenoma with inappropriate TSH incretion. Transmission computed tomography showed an intrasellar expansion, 16 mm in diameter. The neoplastic TSH production was confirmed by an elevated alpha-subunit and a raised molar alpha-sub/ATSH ratio. However, T4 distribution on prealbumin (PA, TTR), albumin (A) and thyroxine binding globulin (TBG) showed a clearly increased binding to PA (39%), indicating additional prealbumin-associated hyperthyroxinemia. The absolute values of PA, A and TBG were within the normal range. After removal of the TSH-producing adenoma, basal TSH, the free thyroid hormones and T4 binding to prealbumin returned to normal. Therefore, the prealbumin-associated hyperthyroxinemia had to be interpreted as a transitory phenomenon related to secondary hyperthyroidism (T4 shift from thyroxine binding globulin to prealbumin) rather than a genetically conditioned anomaly of protein binding.

Oesophageal disorders are relatively uncommon in large animals. Oesophageal obstruction is the most frequently encountered clinical presentation in bovine and it may be intraluminal or extra luminal (Haven, 1990). Intraluminal obstruction or “choke” is the most common abnormality that usually occurs when foreign objects, large feedstuff, medicated boluses, trichobezoars, or oesophageal granuloma lodge in the lumen of the oesophagus. Oesophageal obstructions in bovine commonly occur at the pharynx, the cranial aspect of the cervical oesophagus, the thoracic inlet, or the base of the heart (Choudhary et al., 2010). Diagnosis of such problem depends on the history of eating particular foodstuff and clinical signs as bloat, tenesmus, retching, and salivation

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.
