A 29-year-old male patient with a functioning pituitary macroadenoma is discussed. The pituitary mass was detected by MRI after the patient presented with sudden onset of headache, suggestive of an apoplectic event. The headache resolved with analgesic medications. Within a follow-up period of one week, the pituitary mass had spontaneously regressed to nearly half its original size without any therapy. The patient never reported any visual complaints and displayed no signs of hypopituitarism. Elevated prolactin levels were present. Seven weeks after the initial event, the pituitary mass showed continued regression on MRI. Prolactin levels remained elevated. This case provides a unique look at the rapid spontaneous regression of mass effect that may occur following apoplexy of a pituitary adenoma.

Background This is a rare association of pituitary adenoma with apoplexy with arteriovenous malformation as only single case was reported prior to this case as per our knowledge. Case Description A 25-year-old man presented with chief complaints of headache of sudden onset, severe in intensity with sudden loss of vision. Imaging shows pituitary adenoma with apoplexy with right parietal arteriovenous malformation. The patient was managed with embolization for parietal arteriovenous malformation and medically for pituitary adenoma with apoplexy. Conclusion Pituitary apoplexy can be treated conservatively if no features of mass effect present. Follow-up of the patient must be done regularly to look for the size of pituitary adenoma and recurrence of arteriovenous malformation.

Object The benefits of treating intracranial aneurysms in the region of the anterior visual pathways are well understood. However, the adverse effects of endovascular stenting across the ophthalmic artery have received little attention. The authors reviewed their experience with patients who had stents deployed across the ophthalmic artery origin. Methods Patients' medical charts and imaging studies were reviewed to identify all patients with a non–flow diverting stent deployed over the ophthalmic artery origin for the treatment of intracranial aneurysms. All patients with neuro-ophthalmic complaints were referred for formal ophthalmological evaluation. Results A total of 104 consecutive patients with 106 aneurysms were identified to meet criteria for inclusion in the study cohort. Preoperatively, 30 patients (29%) described headache symptoms and 32 patients (31%) reported visual complaints. Of the patients with preoperative headaches, 15 (54%) of 28 patients for whom follow-up was available experienced improvement in their symptoms. Of the patients with preoperative visual complaints, improvement was noted in 11 (41%) of the 27 patients for whom follow-up was available, 9 (33%) of 27 patients reported no change in visual symptoms, and 7 (26%) of 27 patients reported progression of symptoms. Visual field defects developing posttreatment were noted to occur in 8 (7.7%) of 104 patients: 3 with immediate postoperative retinal infarcts, 1 with perioperative hemianopia that resolved by the time of discharge, 1 with a subjective visual field defect, 1 with subjective migratory visual field defects, and 2 with nonspecific visual symptoms. Compressive symptoms from aneurysm mass effect were noted in 6 patients preoperatively, with 4 of those patients experiencing persistent worsening, resolution in 1 case, and no change in 1 case. One patient developed a novel cranial nerve palsy from mass effect in the immediate postoperative period. Conclusions Deployment of stents across the ophthalmic artery origin for the treatment of intracranial aneurysms appears to be relatively safe with regard to visual outcomes. Neuro-ophthalmic complaint resolution rates were comparable to endovascular procedures that do not employ stents, with headache resolution rates comparable to coil-only aneurysm obliteration and low rates of retinal ischemic events. For patients presenting with mass effect, stent-assisted coiling appears to be less effective than microsurgery with decompression for relief of compressive symptoms.

Abstract A retrospective review of 16 consecutive patients with pituitary apoplexy treated over a 10-year period is reported. Eight men and 8 women (mean age, 48 years) underwent transsphenoidal decompression after an average duration of symptoms of 19 days. The diagnosis of pituitary apoplexy was made by the sudden onset of headache (88%), nausea (56%), or meningismus (13%), with or without visual disturbances (75%), in the setting of a sellar tumor on computed tomographic or magnetic resonance imaging scans. Thirteen of 16 patients showed significant improvement of symptoms after surgery (average follow-up, 2.5 years). In addition, 5 patients with clinically silent yet extensive pituitary hemorrhage were treated. Although extensive pituitary hemorrhage often produced fulminant apoplexy, it also presented insidiously over many days with few, if any, clinical signs. Rapid diagnosis, endocrine replacement, and transsphenoidal decompression constituted effective therapy. Magnetic resonance imaging (after at least 12 hours of symptoms) was superior to computed tomography in detecting hemorrhage.

Rathke cleft cyst is described as benign intrasellar cyst. They are mostly small and asymptomatic; they may become large enough to cause symptoms by compression of intrasellar or suprasellar structures. We report on a case of spontaneous regression of a symptomatic RCC with subsequent recovery of preexisting endocrine dysfunction and resolution of headaches. A 60-year-old man complained about headaches. Laboratory investigation revealed a partial hypopituitarism with a slight central hypothyroidism without need for substitution. An MRI study showed a cystic, T2-hyperintense, sellar lesion compatible with a RCC. At one year follow-up, the patient had no complaints and the hormone work-up revealed a regression of the previous slight hypopituitarism. The MRI study showed a complete regression of the cystic lesion and a normal sized and shaped pituitary gland. The spontaneous regression of cystic sellar lesions is rare. The exact mechanism of the possible spontaneous involution of RCC is until now not well understood. However, spontaneous regression is possible and justifies the conservative therapy with regular clinical and radiological follow-up for asymptomatic patients or patients with symptoms not caused by the mass effect of these lesions.

Background: Pituitary apoplexy is syndrome of sudden onset of headache, visual loss, pituitary dysfunction, and altered consciousness. Pituitary apoplexy followed by acute cerebral ischemia is extremely rare. Here, we introduced the case of successful surgical resection of pituitary adenoma which induced acute cerebral ischemia. Case Description: A 78-year-old man with a known pituitary macroadenoma presented with decreased consciousness and left hemiparesis. Magnetic resonance image (MRI) and computed tomography (CT) showed large pituitary macroadenoma with hemorrhage and diffusion-perfusion mismatch of right internal carotid artery (ICA) territory. Conventional angiography was done and severe stenosis of bilateral ICA and prominent flow delay of left ICA were noted at paraclinoid segment. Microscopic tumor mass removal with transsphenoidal approach was performed. Final pathological diagnosis was pituitary adenoma with apoplexy. Immediately after surgery, his symptoms were disappeared. Follow-up image studies revealed much improved perfusion in right ICA territory and patency of bilateral ICAs. Conclusion: Direct compression of ICA is rare complication of pituitary apoplexy, which caused cerebral ischemia. Conventional angiography should be necessary for accurate diagnosis and prompt surgical decompression should be the treatment of choice.

An 83-year-old white man presented with a rapidly growing conjunctival mass in his left eye over the course of 1 month. While awaiting surgical intervention, the tumour underwent partial, spontaneous regression to half its original size. The lesion was ultimately excised with wide margins using a no-touch technique and application of cryotherapy to the corneal and conjunctival margins and scleral bed. Histopathological analysis revealed a conjunctival keratoacanthoma. To our knowledge, this is the first case documenting the partial, spontaneous regression of a conjunctival keratoacanthoma over a 5 week time course from the time of diagnosis to surgical excision.

Background:Since the first reported use of percutaneous transluminal coronary angioplasty, advances in the interventional cardiology arena have been fast paced. Developers and clinicians are adapting from the learning curve awarded by the time-course of drug-eluting stent (DES) evolution. BioMime™ sirolimus-eluting stent (SES) is a step towards biomimicry. The stent is built on a strut of ultra-low thickness (65μm), a cobalt–chromium platform using an intelligent hybrid of closed and open cells allowing for morphology-mediated expansion. It employs a well-known antiproliferative – sirolimus – that elutes from a known biodegradable copolymer formulation within 30 days. The resultant stent demonstrates almost 100% endothelialisation at 30 days in preclinical models.Methods:The meriT-1 was a prospective, single-arm, single-centre trial to evaluate the safety and efficacy of BioMime SES in 30 patients with a single de novo lesion in native coronary arteries. The primary safety and efficacy end-points were major adverse cardiac events (MACE) at 30 days and in-stent late lumen loss at eight months, as measured using quantitative coronary angiographic (QCA) method. Secondary safety and efficacy end-points included MACE at one and two years and angiographic binary restenosis at eight-month angiographic follow-up. Other end-points included the occurrence of stent thrombosis at acute, subacute, late and very late periods and the percentage of diameter stenosis by QCA.Results:No MACE were observed and the median in-stent late luminal loss in 20 (67%) subjects studied by QCA was 0.15mm, with 0% binary restenosis at eight-month follow-up. No stent thrombosis was observed up to one-year follow-up.Conclusions:In comparison to currently available DES, BioMime SES appears to have a considerable scientific basis for prevention of neointimal proliferation, restenosis and associated clinical events.

Abstract Background Pregnancy is a known risk factor for pituitary apoplexy, which is life threatening for both mother and child. However, very few clinical interventions have been proposed for managing pituitary apoplexy in pregnancy. Case presentation We describe the management of three cases of pituitary apoplexy during pregnancy and review available literature. Presenting symptoms in our case series were headache and/or visual disturbances, and the etiology in all cases was hemorrhage. Conservative therapy was followed until 34 weeks of gestation, after which babies were delivered by cesarean section with prophylactic bolus hydrocortisone supplementation. Tumor removal was only electively performed after delivery using the transsphenoidal approach. All three patients and their babies had a good clinical course, and postoperative pathological evaluation revealed that all tumors were functional and that they secreted prolactin. Conclusions Although the mechanism of pituitary apoplexy occurrence remains unknown, the most important treatment strategy for pituitary apoplexy in pregnancy remains adequate hydrocortisone supplementation and frequent hormonal investigation. Radiological follow-up should be performed only if clinical symptoms deteriorate, and optimal timing for surgical resection should be discussed by a multidisciplinary team that includes obstetricians and neonatologists.

Abstract Background This study evaluated the time course of computed tomography (CT) findings of patients with COVID-19 pneumonia who required mechanical ventilation and were treated with favipiravir and steroid therapy. Results Eleven patients with severe COVID-19 pneumonia were included. CT findings assessed at the three time points showed that all patients had ground-glass opacities (GGO) and consolidation and mixed pattern at intubation. Consolidation and mixed pattern disappeared in most of the patients whereas GGO persisted in all patients at 1-month follow-up. In addition to GGO, a subpleural line and bronchus distortion and bronchial dilatation were frequent findings. The degree of resolution of GGO varied depending on each patient. The GGO score correlated significantly with the time from symptoms onset to initiation of steroid therapy (ρ = 0.707, p = 0.015). Conclusions At 1-month follow-up after discharge, non-GGO lesions were absorbed almost completely, and GGO were a predominant CT manifestation. Starting steroid therapy earlier after onset of symptoms in severe COVID-19 pneumonia may reduce the extent of GGO at 1-month follow-up.
