“…The etiological mechanism behind hemorrhage into RCCs is obscure, but usually there is no identified antecedent traumatic or other inciting event. Also of note is the fact that, since the time of Paulus et al , numerous parallel examples of hemorrhage into other types of benign cysts such as arachnoid cysts , colloid cysts or even epidermoid or developmental cysts have been reported. Some of these bleeds have been linked to trauma, but many have been spontaneous events.…”

Xanthomatous lesions of the sellar region have traditionally been divided into two separate categories, xanthomatous hypophysitis (XH) and xanthogranuloma (XG) of the sellar region. The seminal article on XH, a condition typified by foamy histiocytes and lymphoplasmacytic infiltrates in the pituitary gland/sellar region, but usually little or no hemosiderin pigment, detailed three patients. However, most reports since that time have been single cases, making understanding of the entity difficult. In contrast, the seminal report on XG, characterized by sellar region cholesterol clefts, lymphoplasmacytic infiltrates, marked hemosiderin deposits, fibrosis, multinucleated giant cells around cholesterol clefts, eosinophilic granular necrotic debris, and accumulation of macrophages, included 37 patients, allowing more insights into etiology. Few examples could be linked to adamantinomatous craniopharyngioma, and although ciliated epithelium similar to that of Rathke cleft cyst (RCC) was identified up to 35% of the 37 cases, it could not be proven that XG was related to hemorrhage into RCC. Case reports since that time, however, occasionally linked XG to RCC when an etiology could be identified at all, and a few recognized that a spectrum exists in xanthomatous lesions of the sella. They review literature, adding 23 cases from our own experience, to confirm that overlap occurs between XH and XG, and that the majority-but not all-can be linked to RCC leakage/rupture/hemorrhage. It was suggested that progressive accumulation of hemosiderin pigment in the lesion, possibly caused by the multiple episodes of bleeding, could account for the transition of at least some cases of XH to XG.

“…[44] Reviewing the literature, we found 57 reports published during 1976-2019, with a total number of 183 cases of CSDH in association with AC with age ranging between 3 years and 58 years [Table 1]. [1,7,8,[11][12][13][14][15][16][17][20][21][22]25,26,29,30,33,34,36,39,40,42,45,46,48,[54][55][56][57][58][59][60]63,64,[66][67][68][69][70][71] ere were 31 single case reports, 12 publications reporting on 2-3 patients, and 14 case series reporting on 5-16 patients. ere are some data to support that the coexistence of CSDH and AC is not incidental, and two pathogenic mechanisms were proposed to explain such association.…”

Background: Arachnoid cysts (ACs) are benign, congenital, fluid-filled collection between two layers of the arachnoid membrane accounting for about 1% of all the intracranial space occupying lesions. These lesions are usually asymptomatic and detected incidentally by magnetic resonance imaging (MRI) or computed tomography scan imaging (CT). However, these lesions can present as spontaneous chronic subdural hematoma (CSDH) causing neurological deficits that require neurosurgical intervention. Case Description: We report a case of CSDH associated with AC in a 14-year-old Kuwaiti boy who presented with a 2 weeks history of headache, which was worsening over the time. Brain CT scan demonstrated a left frontotemporal large CSDH in contact with an underlying temporal AC that appeared isodense to the CSF. The patient underwent an emergency surgery to evacuate the CSDH through a burr hole, while the AC was left intact. During the postoperative period, the patient showed good recovery in terms of neurological symptoms. Follow-up MRI showed stable size of the AC with no recurrence of the CSDH. Conclusion: Literature’s review was done to determine the best surgical approach in treating spontaneous CSDH associated with AC. Burr hole evacuation of CSDH with irrigation only, leaving the AC intact, is a successful surgical approach for treatment and was associated with good outcome.
