Pancreatic dermoid cysts are a rare entity. Preoperative diagnosis is difficult. The diagnosis is generally taking intraoperative. A 20-year-old female presented with epigastric pain without nausea, vomiting, diarrhea, fever, jaundice, and weight loss of one-month duration. Ultrasonography and computed tomography showed a smooth borders, solid, hyperechoic tumor within midline abdomen, without any connection to the stomach or spleen. At surgery, the entire mass was excised off of the head and inferior part of pancreas. Histopathologic evaluation revealed the rare diagnosis of a dermoid cyst. The diagnosis is difficult preoperatively in evaluating cystic pancreatic lesions by imaging. Therefore, we want to summarize the literature on this rare entity knowledge.
BACKGROUND Ranulas are typical causes of sublingual cysts in children. However, our case was histopathologically confirmed to be a dermoid cyst. Epidermoid and dermoid cysts of the floor of the mouth account for <0.
Purpose: The O-RADS malignancy risk stratification of typical ovarian dermoid cysts by using a 10 cm threshold is based on expert consensus rather than analysis of objective clinical data. This comprehensive scoping review consolidated all currently available studies evaluating typical benign ovarian dermoid cyst size and risk for malignant transformation.
Methods: A systematic review of MEDLINE, Embase, Scopus and the Cochrane library was performed from inception to January 14, 2024, using PRISMA-ScR guidelines.
A 36-year-old woman referred to our hospital for treatment of a mediastinal tumor. Contrast computed tomography (CT) scan was revealed a 31×21×25 mm mass in the anterior mediastinum, with low contrast, clear border, and a tendency to increase. On magnetic resonance imaging( MRI) examination, the anterior mediastinal tumor showed homogeneous high signal intensity on T1-weighted images and a combination of high and low signal intensities on T2-weighted images.
This is the case of a 22-year-old female who arrived at our institution after experiencing refractory insomnia, disorganized behavior, inappropriate laughter, and anorexia. Upon admission, a physical examination revealed mutism, irritability, and visual hallucinations. Infectious, metabolic, and other, alternative, causes for the presenting symptoms were excluded.
Dermoid cysts originate from embryonic tissues trapped in the cranial fusion lines and typically manifest extra-axially. However, intradiploic dermoid cysts are rare among cranial tumors, and their rupture has been sparsely documented. We present a case showcasing a remarkable phenomenon-the spontaneous rupture of an intradiploic dermoid cyst into the subarachnoid space, displaying a distinct "volcano-like" appearance on CT and MRI scans.
