Insight Into

The authors describe imagiological findings in idiopathic exudative polymorphous vitelliform maculopathy. A 41-year-old woman complained of bilateral blurry vision. Best-corrected visual acuity was 20/20 bilaterally. Bilateral small serous neurosensory detachments in the fovea were seen at fundoscopy and confirmed by spectral-domain optical coherence tomography. Fluorescein angiography was unremarkable. Indocyanine green angiography presented discrete hyperfluorescent spots on the posterior pole. Later, more bleb-like lesions with a vitelliform appearance and hyperautofluorescent on blue fundus autofluorescence were detected. One year later, a complete resolution of the fluid was observed. To conclude, multimodal evaluation of patients with idiopathic exudative polymorphous vitelliform maculopathy is essential for the correct diagnosis of this disease.

A 28-year-old man presented to the emergency room with blurred vision in the right eye for two days. He reported a preceding flu-like illness one week earlier. His best-corrected visual acuity (BCVA) was 20/40 in the right eye and 20/25 in the left eye. There was no anterior chamber inflammation or vitritis in either eye. He presented multiple yellowish-white placoid lesions in the posterior pole, some involving the foveal area, bilaterally. General examination and systemic investigation were unremarkable. Multimodal evaluation with fluorescein angiography, indocyanine green angiography, and spectral domain and optical coherence tomography angiography (OCTA) were consistent with the diagnosis of acute posterior multifocal placoid pigment epitheliopathy. Due to centromacular involvement with decreased BCVA, treatment with oral methylprednisolone was started after infectious causes were ruled out. After two weeks, the patient presented functional and anatomical improvement. OCTA showed partial reperfusion of the choriocapillaris in the affected areas, in both eyes.

Background/aimsTo describe clinical and multimodal imaging features in a cohort of choroidal macrovessels.MethodsDemographics and multimodal imaging features of 16 eyes of 13 patients with choroidal macrovessels were reviewed. The multimodal imaging included colour fundus photography, fundus autofluorescence (FAF), spectral domain enhanced depth imaging optical coherence tomography (OCT), en face OCT, OCT-angiography (OCT-A), B-scan ultrasonography (US), fluorescein angiography (FFA) and indocyanine green angiography (ICGA).ResultsThree patients had bilateral involvement. On colour fundus photography, three patterns were evident (a clearly visible orange-red vessel; a track of pigmentary changes; spots of mild pigmentary changes). Vessel orientation was horizontal (11 eyes), oblique (4 eyes) or vertical (1 eye). In 2 eyes, the vessel was extra-macular. OCT in all cases showed a hyporeflective choroidal area with posterior shadowing and elevation of the overlying retina. Subretinal fluid was present in 4 eyes. FAF (12 eyes) was normal (7 eyes) or showed a hypofluorescent/hyperfluorescent track (4 eyes) or linear hyperautofluorescence (1 eye). En-face OCT (2 eyes) revealed the course of the macrovessel at the level of choroid and choriocapillaris. On OCT-A (2 eyes) the vessel had a reflectivity similar to surrounding vessels but larger diameter. B-scan US (8 eyes) showed a nodular hypoechogenic lesion. FFA (5 eyes) showed early focal hyperfluorescence (4 eyes) not increasing in later phases, or was normal (1 eye). ICGA (6 eyes) showed early hyperfluorescence of the vessel.ConclusionsChoroidal macrovessels can mimic other entities, leading to underdiagnosis. Appreciating relevant features on different imaging modalities will aid a correct diagnosis.

SummaryA further case of parahaemophilia is reported. One year after the correct diagnosis had been made the patient had to undergo cholecystectomy which was performed under prophylactic substitutive treatment with fresh plasma at a factor V level of 31 %. A minimal factor V level of 11 to 12% was maintained throughout the first week after operation. There was no abnormal postoperative bleeding. The half disappearance time of factor V was found to be about 12 h. Infusion of equivalent amounts of fresh plasma supplied a higher yield of factor V in the patient’s plasma before operation than postoperatively what may be explained by an increased diffusion of factor V into the intercellular space resulting from a postoperatively increased capillar permeability. The results are compared with those of other authors.

<P>Background: Primary Hepatic Epithelioid Haemangioendothelioma (HEHE) and Primary Hepatic Angiosarcoma (PHA) are rare mesenchymal tumours with different malignant potential. Whereas HEHE demonstrates low to intermediate malignant potential, PHA is an aggressive malignancy with poor prognosis. The knowledge of typical imaging features of these lesions may facilitate correct diagnosis; however, the ultimate diagnosis of HEHE and PHA is based on histopathologic examination. </P><P> Discussion: The most typical findings helpful in diagnosing HEHE are: Presence of multiple, confluent nodules located at the liver periphery (in young to middle-aged woman), retraction of the liver capsule, marked hyperintensity on T2-weighted images, “target-sign” appearance, progressive centripetal contrast enhancement, and relatively high Apparent Diffusion Coefficient (ADC) values. More than &#8805;50% of nodules are hyper- or isointense on Hepatobiliary Phase (HBP) images. Conclusion: The imaging features suggestive of PHA are: Occurrence of metastases (lungs, spleen) at the time of diagnosis, presence of a large dominant mass with smaller satellites, heterogeneity and areas of haemorrhage in a dominant mass, progressive contrast enhancement, slightly elevated ADC values as compared to other malignant liver tumours.</P>

Abstract Background Central serous chorioretinopathy (CSC) is characterized by an accumulation of subretinal fluid (SRF) in the macula. It is usually treated by laser photocoagulation or photodynamic therapy (PDT) with consisting of different doses and power. This study aimed to compare the efficacy of half-dose PDT and one-third-dose PDT in chronic or recurrent CSC. Methods A retrospective review of patients with chronic or recurrent CSC who were treated with either a half-dose or one-third-dose PDT, and had follow up 12 months afterwards. Best-corrected visual acuity (BCVA), central retinal thickness (CRT) and resolution of subretinal fluid (SRF) at baseline as well as 1, 3, 6 and 12 months post-PDT were assessed. Results Forty-six eyes and 20 eyes received half-dose and one-third-dose PDT, respectively. The study showed efficacy of the one-third-dose PDT compared with half-dose PDT in BCVA improvement (0.10±0.04 logMAR for one-third-dose versus 0.17±0.04, for half-dose, P=0.148) and CRT improvement (125.6±24.6 μm for one-third-dose versus 139.1±16.54, for half-dose, P=0.933) at 12 months. The SRF recurrence rate was significantly higher in the one-third-dose PDT group compared with the half-dose PDT group (40.0% versus 15.2%, P=0.027) at 12-months. Conclusion At 12 months, the one-third-dose PDT was effective in terms of BCVA and CRT improvement, when compared with half-dose PDT. However, this study showed that one-third-dose PDT had a higher recurrence rate of SRF.

Abstract Background Ventriculitis, a dreaded complication of brain abscess, meningitis, and various neurosurgical procedures, has attracted limited attention in the medical literature. Methods Retrospective single-centre study. We screened medical files of all patients who had a brain imaging report including the word “ventriculitis” during years 2005-2019. Only patients with clinical, microbiological and imaging features of ventriculitis were included. Data were collected through a standardized questionnaire. Results Ninety-eight patients fulfilled inclusion criteria: 42 women and 56 men, median age 60 years [interquartile range 48-68]. Primary mechanism for ventriculitis was classified as follows: brain abscess (n=29, 29.6%), meningitis (n=27, 27.6%), intraventricular catheter-related (n=17, 17.3%), post-neurosurgery (n=13, 13.3%), and hematogenous (n=12, 12.2%). Main neuroimaging features were intraventricular pus (n=81, 82.7%), ependymal enhancement (n=70, 71.4%) and intraventricular loculations (n=15, 15.3%). Main pathogens were streptococci (n=44, 44.9%), Gram-negative bacilli (n=27, 27.6%), and staphylococci (n=15, 15.3%). In-hospital and one-year mortality rates were, respectively, 30.6% (n=30), and 38.8% (n=38). Neurological sequelae were reported in 34/55 (61.8%) survivors, including cognitive impairment (n=11), gait disturbances (n=9), paresis (n=7), behavior disorder (n=6), epilepsy (n=5). On multivariate analysis, age &gt; 65 years, Glasgow Coma Scale score &lt; 13 at initial presentation, status epilepticus, hydrocephalus and positive cerebrospinal fluid culture were associated with one-year mortality. We built a scoring system to stratify patients with ventriculitis into low-risk (12.5%), intermediate-risk (36.5%), and high-risk (71.4%) of death. Conclusion Ventriculitis is a severe complication of brain abscess, meningitis, or neurosurgery, with in-hospital mortality rate of 30%, and neurological sequelae in 60% of survivors.

Purpose: To describe a case of keratouveitis caused by Euphorbia grandicornis sap, that resolved with topic steroids. Methods: We report a case presentation of a patient with keratouveitis. Results: A 70-year-old woman suffered from accidental ocular contact with E. grandicornis sap in her left eye. Two hours after the contact, she attended the clinic due to conjunctival hyperemia and pain. Best-corrected visual acuity (BCVA) was 20/25. The toxic conjunctivitis was treated with topical lubricant and steroid. After 24 h, she presented blurred vision. BCVA was 20/80. Toxic keratouveitis was diagnosed. Topical treatment with 1% cyclopentolate t.i.d., 5% sodium chloride, 1.14% dexamethasone phosphate each hour, and 4% sodium hyaluronate each hour was continued. Complete resolution was obtained 1 week later. Euphorbia sap content analysis was performed using dissolvent extraction spectrophotometry. Its contents included flavonoids, alkaloids, phenols and sesquiterpene lactones. Conclusion: Corneal exposure to E. grandicornis sap is a cause of nonvisually threatening keratouveitis when adequately treated with corticosteroids.

Background: Lipomas are benign fatty tumors made of fat tissue. Bladder lipomas are extremely rare. For this reason, it is necessary to be aware of the imaging features when incidentally detected in imaging. Case Report: In the abdominal computed tomography (CT) performed as part of the follow-up examination of a 43-year-old patient, who had undergone surgery for adrenal adenoma five years earlier, a 14x9x8 mm smoothly marginated, ovoid-shaped, hypodense mass lesion with a homogeneous internal structure was detected in the anterior bladder wall. The pre-contrast density of the lesion was measured as -105 HU. The magnetic resonance imaging performed one year after the CT examination revealed a 14x9x8 intramural mass in the bladder wall, showing protrusion toward the lumen. The group was observed to be markedly hypointense on fat-suppressed T1 and T2-weighted images and considered consistent with a bladder lipoma. Discussion: Bladder lipomas are benign lesions that can vary in clinical presentations but usually cause hematuria. The differential diagnosis of bladder lipomas includes other mesenchymal rare benign tumors that can arise from the urinary bladder submucosal layer, including leiomyoma, hemangioma, plasmacytoma, fibroma, and neurofibroma, in imaging bladder lipomas present as homogeneous lesions containing macroscopic fat. Only the liposarcoma and pelvic lipomatosis could also show similar features. The less differentiated liposarcomas tend to present more heterogeneous enhancement, irregular-shaped margins, and infiltrative behavior. Also, appropriate multiplanar reconstructions may allow the radiologist to determine it is an extravesical pelvic lipomatosis. Conclusion: Using CT and MRI, these lesions rich in adipose tissue can be distinguished from other lesions, and their diagnosis can be made to a great extent. However, a histopathological examination is required for a definitive diagnosis.

IntroductionNormal pressure hydrocephalus (NPH) occurs in 0.5% of persons over 65 years old. The etiology of NPH is still unknown. Clinically NPH is characterised by cognitive deterioration, gait impairment and urinary incontinence. NPH is a possible reversible cause of dementia. Neuroimaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) allow to assess typical brain changes in this disorder.The objectives are to present the typical findings of NPH on CT and MRI and to demonstrate differences between NPH and central brain atrophy in neuroimaging.ResultsThe imaging features of NPH include: supratentorial ventriculomegaly with callosal angle less than 90o, tight sulci at the vertex and considerable out of proportion enlargement of Sylvian fissures. In case of central brain atrophy there may be a predominance of ventriculomegaly and/or widened sulci without crowding of the gyri at the vertex and callosal angle greater than 90o. In both entities, the decrease of density in periventricular region may be seen: in NPH could be a sign of transependymal oedema or in brain atrophy as an accompanying leukoaraiosis. Additionally, it is possible to assess changes in flow of cerebrospinal fluid (CSF) on MRI: in NPH an increased pulsatile CSF circulation in aqueduct as flow void sign may be observed.ConclusionsCorrect diagnosis of NPH on CT or MRI in relation to clinical data is very important. Treatment with ventriculoperitoneal shunt or third ventriculostomy may partially improve the quality of life in some patients with cognitive impairment due to NPH.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Purpose: To report the management and outcome of an unusual case of occupational perforating ocular industrial nail injury involving the posterior pole. Methods: Observational case report. A 48-year-old Chinese male construction worker presented with perforating industrial nail injury.Results: The patient underwent primary globe repair and foreign body removal followed by staged pars plana vitrectomy with endophotocoagulation and cyclopropane gas tamponade for repair of the vitreous incarceration at the posterior exit wound, a subsequent laser retinopexy with silicone oil tamponade for an inferior retinal detachment extending from the perforation site and finally silicone oil removal with a scleral fixated intraocular lens implant. His best-corrected visual acuity improved to 20/100 six months after the initial injury. Conclusion: Perforating ocular injuries involving the posterior pole often present with severe visual impairment and significant management challenges. We report a case of perforating ocular nail injury, which was managed successfully with staged surgical procedures.
