“…12,21,22 Low signal on T1-weighted MRI, similar to CSF, occurs if protein concentration is low, whereas high signal is associated with a high protein concentration. 4,24 The most common MRI signal patterns were hypointensity on T1-weighted and hyperintensity on T2-weighted images, isointensity on T1-weighted and hyperintensity on T2-weighted images, and hyperintensity on both T1-weighted and T2-weighted images, similar to other reports. 14,25 The cyst wall, rather than the cyst contents, was patchy or showed enhancement, reflecting pericystic inflammation, residual pituitary gland or squamous epithelium.…”

“…On MRI, they usually appear as iso-or hypointense on T1 and T2-weighted images and tend to have homogeneous enhancement following radio-contrast administration. 14 To our knowledge, only two previous reports have described the simultaneous existence of a pituitary adenoma with a primary pituitary lymphoma. 6,7 Kuhn et al have reported a patient harbouring a mixed T-cell lymphoblastic lymphoma and a pituitary adenoma with immunoreactivity to FSH, diagnosed 25 years after the initial resection of the adenoma.…”

OBJEcTIVE: Primary central nervous system (cNs) non-Hodgkin's lymphoma is a rarely encountered clinical entity. Here we present a case of a primary cNs diffuse large B-cell nonHodgkin's lymphoma developed on a previously operated and irradiated pituitary macroadenoma. DEsIGN-rEsULTs: A 60-year-old woman presented with muscle weakness and eye lid ptosis. Thirty years ago, she was diagnosed with a non-functioning pituitary macroadenoma requiring repeated incomplete operations and conventional radiotherapy and accompanied by partial anterior pituitary deficiency. On admission, the magnetic resonance imaging (MrI) identified a pituitary sellar mass extending into the suprasellar region, compressing the optic chiasm and invading the left cavernous sinus. Following transsphenoidal surgery, the histological investigation revealed the presence of a diffuse large B-cell non-Hodgkin's lymphoma without other loci from the systemic staging. Following chemotherapy and despite a marked resolution of the neoplastic pituitary mass in the post-chemotherapy MrI scan, the patient's course was complicated with consciousness deterioration attributed to epileptic seizures and she died of a hospital acquired infection. cONcLUsIONs: clinicians should include primary cNs lymphoma in the differential diagnosis of an isolated invasive sellar mass. The possible association of primary cNs lymphoma development with the history of operated and irradiated pituitary adenoma is herein discussed.

“…Our patient presented a partial hypopituitarism with a suprasellar mass in brain MRI. Pituitary adenoma is the most common cause of hypopituitarism [1]. Suprasellar masses are varied in aetiology; craniopharyngioma, Rathke cleft cyst, germ cell tumour and granulomatous processes are others common differential diagnosis [1].…”

“…The most common etiology of hypopituitarism is the pituitary adenoma, accounting for 10 to 15% of intracranial neoplasms [1]. Differentiation among various etiologies may not always be easy, since many of these lesions may mimic the clinical, endocrinologic and radiologic presentations of pituitary adenomas.…”

Symptomatic hypopituitarism revealing primary suprasellar lymphoma

BackgroundThe most common cause of hypopituitarism is pituitary adenoma. However, in the case of suprasellar masses different etiologies are possible. We report an unusual case of primary suprasellar lymphoma presented with hypopituitarism.Case presentationA 26 year old woman presented with amenorrhea, galactorrhea and neurological disorders. Also, the laboratory work-up revealed partial hypopituitarism. The magnetic resonance imaging of the head showed a suprasellar mass. A presumptive diagnosis of granulomatous processes was made and the patient was given steroid therapy. Repeated brain MRI detected new lesions in the brain with regression of the suprasellar mass. Stereotactic biopsy of the paraventricular lesion revealed the diagnosis of B-cell lymphoma.ConclusionThis case presentation reports a rare cause of hypopituitarism. Primary suprasellar lymphoma is extremely rare and represented a real diagnostic challenge. Besides, suprasellar masses are varied in aetiology and can present diagnostic problems for a radiologist. Also, because of the increased incidence of PCNSL, lymphoma must be kept in mind in the differential diagnosis of lesions in the suprasellar region.
