Intracerebral Calcifications Associated with Failure to Thrive and Macular Degeneration in an Adolescent: A Case Report.

Background: The clinical picture of intracerebral calcification is so varied that it constitutes an essential element of a wide range of clinical syndromes of variable expression that continue to be described. In this article, we discuss the diagnostic possibilities of basal ganglia calcification considering the association of failure to thrive and macular degeneration in our patient. Case: A 17-year-old male patient of Congolese origin consulted us for a pyramidal syndrome consisting of upper limb tremors during mobilization and dysgraphia. The patient also presented with a distance vision disorder for which the ophthalmological examination revealed poor visual acuity in both eyes (2/10) and macular degeneration in the left eye. On physical examination, we noted a short stature with a small head circumference in relation to age. The brain scan revealed the presence of bilateral striato-pallidal calcifications giving the appearance of Fahr's disease. However, the association of delay of stature development with microcrania, macular degeneration with reduced visual acuity and basal ganglia calcifications could suggest a wide range of syndromic hypotheses, the most likely of which is Rajab-type cerebral calcification. Conclusion: The association of failure to thrive, macular degeneration, and cerebral calcification of the basal ganglia is revealed as a particular phenotype compared to cases reported in the literature. An in-depth analysis would be necessary to identify a possible genetic basis.

Clinical Characteristics, Therapeutic Options, and Outcomes in Hyperphosphatemic Tumoral Calcinosis: A Systematic Review.

This systematic review was performed to understand better the myriad presentations, various therapeutic options, response to therapy, and its clinical outcomes in hyperphosphatemic tumoral calcinosis (HTC). Full texts were selected according to strict inclusion criteria. All case reports of HTC wherein baseline phosphate was measured, treatment offered was mentioned, and information on follow-up and response to therapy that were available were included. A total of 43 of 188 eligible studies (N = 63 patients) met the inclusion criteria. A list of desired data was extracted and graded for methodological quality. A total of 63 individuals (Males = 33) were included from the 43 eligible case studies. The median age of the patients was 18 (IQR 8-32) years. The most frequently involved sites were the hip/gluteal region (34/63; 53.9%) followed by the elbow/forearm (26/63; 41.2%), and the shoulder (18/63; 28.5%). Three patients had conjunctival calcific deposits. The mean (SD) phosphate was 6.9 (1.1) mg/dL. Among the subjects, 36/63 (57.1%) underwent surgical excision with some form of medical therapy. Two patients underwent only surgical excision (2.1%). One patient was maintained on follow-up (1.6%) and 24/63 (38.1%) patients were treated with medical measures. The median (IQR) follow-up duration was 3 (1-9) years. Regression or reduction in lesion size was reported in 19/63 (30.2%) subjects; 20/63 (31.7%) showed progression, 24/63 (38.1%) had features of stable disease, and mortality was reported in 3 patients (4.7%). We report for the first time a detailed description of the clinical and therapeutic response of HTC. A combination of medical measures aimed at lowering serum phosphate appears to be the cornerstone of treatment, although clinical responses may vary.

Unusual Presentation of Recurrent Calcinosis Cutis in the Right Thumb of a 16-Year-Old Female.

Calcinosis cutis is a quite unusual disease represented by abnormal accumulation of calcium salts in the skin and subcutaneous tissues. Repeated cutis calcinosis means recurrent calcium deposition in pre-existing areas. The case report illustrated the case of a 16-year-old female who had recurrent calcium deposits on the base of her right thumb. The patient initially had swelling at the base of her right thumb, which had been present for six months now. The patient described the dorsal solid mass on top of the thumb base, which was painful and had reduced thumb mobility. There was swelling that became painful, specifically located at the same site as the previous surgery, with thumb restriction and superadded infection at the metacarpophalangeal joint. Routine lab tests, including blood tests and rheumatologic and autoimmune work-ups, were normal. Plain radiographs and ultrasound examinations unveiled the characteristics of calcifications in the thumb tissues. A skin biopsy was done and the calcium deposits in subcutaneous tissue were confirmed, matching calcinosis cutis. The approach to the treatment of this condition entailed conservative measures. Some included physiotherapy to correct a flexion deformity, antibiotics, painkillers, and daily dressing. The patient was advised to follow up and to consider excision of the nodules. This case points out the clinical manifestations, investigations, and initial management of available strategies for recurrent calcinosis cutis. Further studies and long-term follow-up are necessary to determine the optimal treatment approaches and outcomes for this rare condition.

Effectiveness of generic tofacitinib in idiopathic inflammatory myositis (IIM)-a retrospective analysis from Indian Myositis Registry (MyoIN).

OBJECTIVES: Determine domain-based-outcomes and steroid-sparing efficacy of generic tofacitinib in IIM. METHODS: This is a multicenter retrospective study wherein clinical phenotype, autoantibody profile, prior immunosuppressives, and outcomes at 3, 6, and 12 months were retrieved for IIM patients prescribed tofacitinib. Overall clinical response was assessed as complete or partial remission as per physician judgment. Changes in cutaneous and calcinosis domain were recorded as per physician global assessment (PGA), lung domain as per medical research council (MRC) dyspnea scale, and muscle strength by Manual Muscle Testing-8 (MMT-8). RESULTS: Forty-two patients of IIM with mean age 38.7 ± 16 years; (76.2% (N = 32) women), median duration of illness 48 (19;88) months were included. Commonest indication for initiating tofacitinib was either for refractory or as steroid sparing for cutaneous domain (N = 25/42, 59.5%) followed by calcinosis (N = 16/42, 38%). Overall complete and/or partial remission was achieved in 23/37 (64.8%), 30/35 (85.7%), and 29/30 (96.6%) patients at 3, 6, and 12 months, respectively. At 12-month follow-up, there was a reduction in prednisolone dose, with absolute decrease from a daily dose of 17.5 mg (IQR 5;50) to 2.5 mg (IQR 0;5) (p < 0.001). Individual domain assessments revealed improvement in cutaneous domain [16/25 (64%)] and calcinosis [6/15 (40%)]. Adverse effects included herpes zoster (N = 2/42, 4.8%) and dyslipidemia (N = 4/42, 9.5%). CONCLUSIONS: Treatment with generic tofacitinib significantly reduces the daily dose of corticosteroids and is effective in cutaneous domain including calcinosis in IIM. KEY POINTS: • This multicenter retrospective study is the first real-world data from India, elucidating steroid sparing efficacy of generic tofacitinib in patients with inflammatory myositis. • Domain-based outcome assessment suggests good clinical improvement especially in cutaneous domain, even those with refractory disease. • Modest benefits were evident in calcinosis, but its effect on the muscle and pulmonary domain appears limited.

Diagnosis of these pathologies causes difficulties for practitioners, and treatment methods have fundamental differences. In this regard, the description of this case is relevant and significant. The algorithm of the main and additional research methods to confirm the diagnosis is described.

Surgical Management of Tumoral Calcinosis of the Hand: A Case Report.

Primary tumoral calcinosis is a rare and benign condition characterized by calcium salt deposition in periarticular soft tissues. It typically presents as a firm, rubbery mass that arises around large joints. While an estimated 250 cases have been described since its discovery, very few cases have been identified in the hand. We present a case of multiple calcified masses in the hand, one of which required meticulous dissection from a digital neurovascular bundle, and our technique for surgical excision. We present this case to lower the threshold for clinical suspicion of tumoral calcinosis for patients who present with a soft tissue mass in the hand. Furthermore, we recommend prompt surgical excision due to low success rates of alternative treatment options and to prevent potential neurovasculature or tendon injury.

Treatment of calcinosis cutis associated with autoimmune connective tissue diseases.

Calcinosis cutis is a condition that is commonly associated with autoimmune connective tissue diseases. It is characterized by the deposition of insoluble calcium salts in the skin and subcutaneous tissue, which can cause pain, impair function, and have significant impacts on quality of life. Calcinosis cutis is difficult to manage because there is no generally accepted treatment: evidence supporting treatments is mostly comprised of case reports and case series, sometimes yielding mixed findings. Both pharmacologic and procedural interventions have been proposed to improve calcinosis cutis, and each may be suited to different clinical scenarios. This review summarizes current treatment options for calcinosis cutis, with discussion of recommendations based on patient-specific factors and disease severity.

ULTRASOUND IMAGING AND PATHOLOGIC FEATURES OF IDIOPATHIC SCROTAL CALCINOSIS IN A YOUNG ADULT NIGERIAN AND REVIEW OF THE LITERATURE.

Background: Idiopathic scrotal calcinosis is a rare and benign disease of the scrotal skin that presents as solitary or multiple painless calcified nodules or papules in the absence of systemic disorders of calcium or phosphorus metabolism. Although some theories have been proposed as to the cause of this rare disease, the exact cause remains unknown. In a resource-poor medical setting like Nigeria, a confident diagnosis of this condition can be made with ultrasonography. Objective: The objective of this report is to emphasize the role of ultrasound in the imaging diagnosis of idiopathic scrotal calcinosis. Case Presentation: This is a case report of a 38-year-old man who presented with recently discharging but longstanding multiple painless scrotal nodules of 22-years duration. Conclusion: This case illustrates the prompt and accurate diagnosis of idiopathic scrotal calcinosis using an ultrasound, a readily available imaging modality in a low-resource setting.Although histology remains the gold-standard for diagnosing idiopathic scrotal calcinosis following surgical excision, this benign disorder has unique sonographic characteristics that could aid the radiologist in making a confident diagnosis.

Calcinosis Prevalence in Autoimmune Connective Tissue Diseases-A Retrospective Study.

Background/Objectives: Calcinosis cutis is the deposition of insoluble calcium salts, which may cause inflammation, ulceration, pain, and restricted joint mobility. It rarely develops in damaged tissues (dystrophic subtype), most frequently in autoimmune connective tissue diseases (CTDs), but there is very limited data on the prevalence. Also, therapy remains an unsolved issue. In this study, we aimed to collect data on the prevalence of calcinosis in CTD patients to highlight that it is a considerable problem. Methods: A retrospective study was conducted in our department to assess the epidemiology of dystrophic calcinosis in CTDs between January 2003 and January 2024. Results: A total of 839 CTD patients were identified, of whom 56 had calcinosis (6.67%). The mean age of the calcinosis patients at diagnosis of underlying CTD was 41.16 ± 19.47 years. The mean time interval from the onset of calcinosis was 5.96 ± 8.62 years. Systemic sclerosis was the most common CTD complicated by calcinosis (n = 22). Conclusions: Our results are comparable to those reported previously in the literature. Although calcinosis is rare in the overall population, it is a present and unsolved problem in CTD patients. Therefore, further studies are needed on the factors involved in the development and progression of calcinosis as well as its treatment.

Solanum glaucophyllum intoxication in goats: Case study.

Solanum glaucophyllum is a toxic plant with calcinogenic effect that causes enzootic calcinosis (EC) characterized by soft tissue metastatic mineralization mainly in cattle and rarely sheep, buffaloes, pigs, horses, and goats. We describe an outbreak of EC in a herd of 64 goats due to S. glaucophyllum consumption. Thirty-four goats were affected exhibiting hirsutism, stiffening, kyphosis and emaciation. Twelve goats died. Grossly, tissue mineralization was observed in the aorta and carotid arteries, lungs, and heart. Lesions were characterized by multiple rough white plaques, and hardened tissues with loss of elasticity. Microscopically, multisystemic mineralization was observed in aorta and carotid arteries, heart, lung, abomasum, intestine, spleen, lymph nodes, kidney, spleen, and meninges, characterized by extensive granular basophilic deposits of tunica media and/or intima of blood vessels; confirmed as calcium salt deposits with Von Kossa stain. We conclude that ingestion of S. glaucophyllum can cause EC in goats. Though EC is rare in goats under some conditions such as heavy drought and abundant S. glaucophyllum exposure disease can develop.

Histological Changes in the Popliteal Artery Wall in Patients with Critical Limb Ischemia.

INTRODUCTION: This prospective study aims to illustrate the histopathological arterial changes in the popliteal artery in peripheral arterial disease of the lower limbs. MATERIAL AND METHOD: A total of 60 popliteal artery segments taken from patients who had undergone lower limb amputation were examined between April and June 2023. The degree of arterial stenosis, medial calcinosis, and the vasa vasorum changes in the arterial adventitia were quantified. The presence of risk factors for atherosclerosis was also observed. RESULTS: Atherosclerotic plaque was found in all of the examined segments. Medial calcinosis was observed in 40 (66.6%) of the arterial segments. A positive association between the degree of arterial stenosis and the vasa vasorum changes in the arterial adventitia was also found (p = 0.025). The level of blood sugar and cholesterol were predictive factors for the severity of atherosclerosis. CONCLUSIONS: Atherosclerosis and medial calcinosis are significant in patients who underwent lower limb amputation. Medial calcinosis causes damage to the arterial wall and leads to a reduction in responsiveness to dilator stimuli.

Dystrophic calcinosis: structural and morphological composition, and evaluation of ethylenediaminetetraacetic acid ('EDTA') for potential local treatment.

BACKGROUND: To perform a detailed morphological analysis of the inorganic portion of two different clinical presentations of calcium-based deposits retrieved from subjects with SSc and identify a chemical dissolution of these deposits suitable for clinical use. METHODS: Chemical analysis using Fourier Transform IR spectroscopy ('FTIR'), Raman microscopy, Powder X-Ray Diffraction ('PXRD'), and Transmission Electron Microscopy ('TEM') was undertaken of two distinct types of calcinosis deposits: paste and stone. Calcinosis sample titration with ethylenediaminetetraacetic acid ('EDTA') assessed the concentration at which the EDTA dissolved the calcinosis deposits in vitro. RESULTS: FTIR spectra of the samples displayed peaks characteristic of hydroxyapatite, where signals attributable to the phosphate and carbonate ions were all identified. Polymorph characterization using Raman spectra were identical to a hydroxyapatite reference while the PXRD and electron diffraction patterns conclusively identified the mineral present as hydroxyapatite. TEM analysis showed differences of morphology between the samples. Rounded particles from stone samples were up to a few micron in size, while needle-like crystals from paste samples reached up to 0.5 µm in length. Calcium phosphate deposits were effectively dissolved with 3% aqueous solutions of EDTA, in vitro. Complete dissolution of both types of deposit was achieved in approximately 30 min using a molar ratio of EDTA/HAp of ≈ 300. CONCLUSIONS: Stone and paste calcium-based deposits both comprise hydroxyapatite, but the constituent crystals vary in size and morphology. Hydroxyapatite is the only crystalline polymorph present in the SSc-related calcinosis deposits. Hydroxyapatite can be dissolved in vitro using a dosage of EDTA considered safe for clinical application. Further research is required to establish the optimal medium to develop the medical product, determine the protocol for clinical application, and to assess the effectiveness of EDTA for local treatment of dystrophic calcinosis.

Pulmonary alveolar microlithiasis combined with gastric mucosal calcification: a case report.

Background: Pulmonary alveolar microlithiasis (PAM) is a rare disease whose clinical and imaging manifestations are non-specific, characterized by the deposition of microliths, which primarily consist of calcium and phosphorus, within the alveoli. In the cases of PAM, patients combined with calcification of other organs such as gastric mucosal calcification are less common. Case presentation: A 59-year-old woman was admitted to our hospital due to cough producing white, foamy sputum, accompanied by dyspnea and fever for 20 days. The CT scan showed diffuse ground-glass opacities and calcification of the gastric mucosa. Lung tissue biopsy revealed the presence of calcification and granulomatous foreign bodies in the interstitium and alveolar cavity. In the later stages, she developed painful skin petechiae. For this patient, the diagnosis of PAM, gastric mucosal calcification, and purpura fulminans was made. However, the genetic test results hinted that the patient and her son had a heterozygous mutation in the FBN1 gene, but her daughter's genetic test results were normal. Although the patient received anti-infection treatment, steroids, and oxygen therapy, her condition did not improve. Conclusion: We reported a rare case of PAM combined with calcification of other organs and purpura fulminans. Treatment of steroids did not show any benefit. The causative mechanism and effective treatment of this disease remain unclear. More treatments need to be explored.

A Sole Case of the FGF23 Gene Mutation c.202A>G (p.Thr68Ala) Associated with Multiple Severe Vascular Aneurysms and a Hyperphosphatemic Variant of Tumoral Calcinosis-A Case Report.

Tumoral calcinosis is an extremely rare genetic disease caused by mutations in three genes, GALNT3, FGF23, and KL, which disrupt phosphorus metabolism. The hallmark of this condition is the formation of tumors in the soft tissues around the joints. Other phenotypic features of tumoral calcinosis are dental involvement and brain and vascular calcifications. The clinical case reported herein presents for the first time to the scientific community the c.202A>G (p.Thr68Ala) mutation of the FGF23 gene, associated with a hyperphosphatemic variant of tumoral calcinosis and multiple severe vascular aneurysms. A female patient underwent multiple surgeries for tumor formations in her soft tissues that first appeared at the age of 12 months. On this occurrence, the patient was found to have hyperphosphatemia, low phosphate clearance, increased tubular reabsorption with normal levels of total and ionized calcium, vitamin D3, and parathyroid hormone, and no effect of treatment with sevelamer hydrochloride and a low-phosphate diet. At the age of 39, the patient underwent imaging studies due to edema and a pulsating formation in the neck area, which revealed multiple vascular aneurysms with thrombosis, for which she received operative and interventional treatment. In this connection, and because of the established phosphorus metabolism disturbance, a genetic disease was suspected. The sequence analysis and deletion/duplication testing of the 358 genes performed on this occasion revealed that the woman was homozygous for a variant of the c.202A>G (p.Thr68Ala) mutation of the FGF23 gene. The established mutation is not present in population databases. The presented clinical case is the first and only one in the world to demonstrate the role of this type of FGF23 gene mutation in the development of a hyperphosphatemic variant of tumoral calcinosis characterized by aggressive formation of multiple vascular aneurysms.

Three Siblings With a Rare Familial Hyperphosphatemia Syndrome: A Case Series.

Hyperphosphatemia familial tumoral calcinosis (HFTC) and hyperphosphatemia hyperostosis syndrome (HHS) are rare autosomal recessive disorders caused by mutations in the polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3), fibroblast growth factor 23 (FGF23), or klotho (KL) genes. They are characterized by hyperphosphatemia and recurrent episodes of bone lesions with hyperostosis and/or soft tissue calcinosis. Management options include phosphate-lowering therapies, anti-inflammatory medications, and surgical excision of the calcified masses in significantly disabled cases. We describe three cases from a consanguineous family who were found to have the same genetic mutation caused by a homozygous mutation in intron eight of GALNT3 c.1524+1 G>A (IVS8+1). The first case had a presentation similar to chronic osteomyelitis, while the second one presented with a calcified mass in her gluteal area. The third case presented with left leg pain. Being a rare disease, the findings of tumoral calcinosis/ bony abnormalities, along with elevated phosphate levels, should raise the possibility of this entity. Family history and biochemical findings can help reach the diagnosis.

Acute calcific tendinitis of the longus colli: A case report.

Acute calcific longus colli tendinitis is a differential diagnosis of neck pain. Typical presentation consists in a triad of symptoms including acute onset neck pain, neck stiffness and odynophagia. Computed tomography (CT) is the gold standard for acute calcific longus colli tendinitis diagnosis and the main radiological findings include prevertebral soft tissue swelling and the presence of amorphous calcifications. The case involves a 39-year-old female who presented to the emergency department with acute unilateral cervical pain that resulted in acute calcific longus colli tendinitis.

Spatial Atlas for Mapping Vascular Microcalcification Using 18F-NaF PET/CT: Application in Hyperphosphatemic Familial Tumoral Calcinosis.

BACKGROUND: Vascular calcification causes significant morbidity and occurs frequently in diseases of calcium/phosphate imbalance. Radiolabeled sodium fluoride positron emission tomography/computed tomography has emerged as a sensitive and specific method for detecting and quantifying active microcalcifications. We developed a novel technique to quantify and map total vasculature microcalcification to a common space, allowing simultaneous assessment of global disease burden and precise tracking of site-specific microcalcifications across time and individuals. METHODS: To develop this technique, 4 patients with hyperphosphatemic familial tumoral calcinosis, a monogenic disorder of FGF23 (fibroblast growth factor-23) deficiency with a high prevalence of vascular calcification, underwent radiolabeled sodium fluoride positron emission tomography/computed tomography imaging. One patient received serial imaging 1 year after treatment with an IL-1 (interleukin-1) antagonist. A radiolabeled sodium fluoride-based microcalcification score, as well as calcification volume, was computed at all perpendicular slices, which were then mapped onto a standardized vascular atlas. Segment-wise mCSmean and mCSmax were computed to compare microcalcification score levels at predefined vascular segments within subjects. RESULTS: Patients with hyperphosphatemic familial tumoral calcinosis had notable peaks in microcalcification score near the aortic bifurcation and distal femoral arteries, compared with a control subject who had uniform distribution of vascular radiolabeled sodium fluoride uptake. This technique also identified microcalcification in a 17-year-old patient, who had no computed tomography-defined calcification. This technique could not only detect a decrease in microcalcification score throughout the patient treated with an IL-1 antagonist but it also identified anatomic areas that had increased responsiveness while there was no change in computed tomography-defined macrocalcification after treatment. CONCLUSIONS: This technique affords the ability to visualize spatial patterns of the active microcalcification process in the peripheral vasculature. Further, this technique affords the ability to track microcalcifications at precise locations not only across time but also across subjects. This technique is readily adaptable to other diseases of vascular calcification and may represent a significant advance in the field of vascular biology.

Eustachian tube calcification as an unusual finding on a panoramic radiograph.

The author herein presents an unusual case of eustachian tube calcification masquerading as loose radiopacities in the temporomandibular joints on a panoramic image, creating a diagnostic challenge. The patient, a 72-year-old woman, presented to the dental service for implant treatment to improve her masticatory function. A cone-beam computed tomography scan was performed and reviewed by a board-certified oral and maxillofacial radiologist. The scan showed no evidence of calcifications in the temporomandibular joints; however, it revealed nodular calcifications within the cartilaginous portion of the eustachian tube bilaterally. Additionally, this report briefly reviews the differential diagnosis of calcified loose bodies in the temporomandibular joint and provides information that needs to be reinforced periodically.

New method of local adjuvant therapy with bicarbonate Ringer's solution for tumoral calcinosis: A case report.

BACKGROUND: Tumoral calcinosis is a condition characterized by deposits of calcium phosphate crystals in extra-articular soft tissues, occurring in hemodialysis patients. Calcium phosphate crystals are mainly composed of hydroxyapatite, which is highly infiltrative to tissues, thus making complete resection difficult. An adjuvant method to remove or resolve the residual crystals during the operation is necessary. CASE SUMMARY: A bicarbonate Ringer's solution with bicarbonate ions (28 mEq/L) was used as the adjuvant. After resecting calcium phosphate deposits of tumoral calcinosis as much as possible, while filling with the solution, residual calcium phosphate deposits at the pseudocyst wall can be gently scraped by fingers or gauze in the operative field. A 49-year-old female undergoing hemodialysis for 15 years had swelling with calcium deposition for 2 years in the shoulders, bilateral hip joints, and the right foot. A shoulder lesion was resected, but the calcification remained and early re-deposition was observed. Considering the difficulty of a complete rection, we devised a bicarbonate dissolution method and excised the foot lesion. After resection of the calcified material, the residual calcified material was washed away with bicarbonate Ringer's solution. CONCLUSION: The bicarbonate dissolution method is a new, simple, and effective treatment for tumoral calcinosis in hemodialysis patients.
