A giant parathyroid adenoma: a case report.
Article in Journal of medical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPrimary hyperparathyroidism is an endocrine disease and a common cause of nonmalignant hypercalcemia, often discovered incidentally in asymptomatic patients. The case reported herein illustrates that significant hormonal imbalances can present with unexpectedly mild clinical manifestations. CASE PRESENTATION: We describe a 47-year-old Caucasian male with two episodes of kidney stones and otherwise no symptoms of severe hypercalcemia. In our case, fasting emerged as a potential risk factor for the development of renal stones. The diagnosis was primary hyperparathyroidism. The intervention consisted of preoperative fluids and cinacalcet while awaiting surgery. Despite initial stability, the patient experienced a subsequent increase in ionized calcium and parathyroid hormone levels, becoming symptomatic with fatigue, tremors, and heart palpitations. This progression led to a diagnosis of a hypercalcemic crisis, and the plan was accelerated. An acute parathyroid scintigraphy and an ultrasound was performed and revealed a giant intrathoracic parathyroid adenoma. After surgical removal of the adenoma, he developed hungry bones and biochemical remission. The patient has received three extracorporeal shock wave lithotripsy treatments for a stone in the upper left kidney, but as of a computed tomography scan on 9 February 2024, the stone remains unchanged. Owing to the stone's resistance to extracorporeal shock wave lithotripsy and the absence of symptoms, no further treatment is planned. Endoscopic laser treatment (retrograde intrarenal surgery) is an option, but for now, the situation will be monitored.
conclusionThis case report underscores that extremely elevated levels of calcium and parathyroid hormone along with a rare giant parathyroid adenoma may not necessarily present with symptoms indicative of a calcium crisis. Additionally, management of such rare giant parathyroid adenomas requires careful monitoring and a tailored approach to address potential postsurgical complications such as hungry bone syndrome.
