2.Three Dimensional Dose Planning Using 6MV X-ay and Multiaxial Computed Tomography for Pituitary Adenoma.
Journal of the Korean Society for Therapeutic Radiology 1985;3(1):59-64
Computation of three dimensional dose distribution using CT image and RT plan was applied to a case of pituitary adenoma. Algorithm was based on two dimensional Tissue Maximum Ratio model extended to the third dimension. The resulting isodose curve of transeverse, coronal and sagittal section was demonstrated. This RT plan allows computation of dose distribution in any arbitarily defined plane in addition to conventional cross sectional view.

A collision tumor involving metastasis to a pituitary adenoma is rare. We describe a case of a 68-year-old Bidayuh woman with underlying treatment-responsive lung adenocarcinoma, who presented with mass effect, panhypopituitarism and polyuria. Her initial imaging study reported pituitary macroadenoma, and she was treated with hormone replacement therapy. She then underwent transsphenoidal tumor debulking surgery with subsequent histopathological findings of a collision tumor of an adenocarcinoma with metastasis to a non-functioning pituitary adenoma.

Intracranial lipomas are benign tumors that may occasionally be found in the suprasellar cistern while pituitary adenomas are far more common brain tumors. Pituitary adenomas may rarely coexist with other intracranial tumors in the sellar-suprasellar region. We share a unique case of a patient with coexisting non-functioning pituitary adenoma and sellar-suprasellar lipoma presenting with blurring of vision. We report a 55-year-old male presenting with a two-year history of blurring of vision with findings of a 2.7 x 3.0 x 3.2 cm homogeneously enhancing lobulated isointense mass on the sellar-suprasellar region. Hormonal workups revealed low cortisol and mildly elevated prolactin. He initially underwent endonasal transsphenoidal excision of the tumor which revealed to be a lipoma on histopathology. Due to minimal improvement of vision from the subtotal excision, he underwent repeat surgery through the transcranial approach which in turn showed a pituitary adenoma.
The co-occurrence of two sellar-suprasellar tumors with different histology is rare, as most of the evidence is based on only a handful of case series. Intracranial lipomas result from persistence and abnormal differentiation of the meninx primitiva during the development of the subarachnoid cisterns. On the other hand, pituitary tumorigenesis is still largely unclear but appears to involve multiple tumor suppressor genes, oncogenes, cell cycle deregulation factors, and miRNAs. Given the differing pathogenesis of each tumor type, the coexistence may only be coincidental. The best surgical approach in this situation is unknown but the focus is on complete excision of the adenoma.

TSH-secreting pituitary adenomas are rare, but have been diagnosed more frequently as radiographic techniques and biochemical assays have improved. These tumors are less easily cured by surgery than are other types of pituitary adenoma because of the large size and invasive features that many attain during the delay to diagnosis. We report a case of TSH-secreting giant pituitary adenoma in which biochemical remission was achieved with surgery.

Two cases of calcified pituitary adenoma are reported, which comprise 2.44% among a surgical series of 82 pituitary adenomas. Both patients had very high serum prolactin level, which suggested the possibility of hormonal influence in formation of the calcification. The tumors were removed by a subfrontal approach to prevent and reduce possible damage to the surrounding structures.
