Article Synopsis
- The study evaluates the microsurgical anatomy of the pericallosal artery, highlighting an unusual brain with three unique anatomical variations.
- Researchers meticulously prepared a brain from a deceased 45-year-old female by washing out arteries, injecting them with red latex, and then preserving the brain in formalin for detailed dissection.
- Three rare anatomical variants were discovered: a right accessory middle cerebral artery, a right bihemispheric anterior cerebral artery, and a median artery of the corpus callosum, illustrating the rarity of finding these combinations in one case.
Background: Hypothyroidism following total laryngectomy or radiotherapy treatment for laryngeal cancer is not a rare event, especially in advanced stages. There are no reports on the incidence of hypothyroidism in patients who received chemotherapy and radiotherapy. The objective of this study is to determine the incidence of thyroid dysfunction in a group of patients with laryngeal cancer who underwent surgery as sole treatment, total laryngectomy or radiotherapy alone, and patients with combined treatment: surgery plus radiotherapy, concomitant chemoradiation therapy and chemoradiation therapy plus salvage surgery.

Case Presentation: A 74 year-old woman with a tumor on the right side of the neck was treated by complete surgical resection.
Unlabelled: A 65 year-old male patient with a one year-duration tumoral growth located in the upper lip was diagnosed on incisional biopsy as epithelial-myoepithelial carcinoma. After wide surgical excision the histopathological analysis revealed the lesion was composed predominantly (>90%) of adenoid cystic carcinoma. In new sections it was found a very small and isolated area of adenoid cystic carcinoma at the bottom of the incisional biopsy.

Case Presentation: We present the case of a 24-year-old male who was diagnosed with a giant retroperitoneal liposarcoma. The patient received palliative treatment due to non-resectability on the basis of chemotherapy.
