ABSTRACT
Primary hyperparathyroidism (PHPT) is the most prevalent cause of hypercalcaemia, affecting 0.3% of the population. The only curative procedure is parathyroidectomy. Ectopic adenomas are challenging to localize and frequently result in persistent PHPT. This is a case report of a 29-year-old male patient who was diagnosed with PHPT prior to neck surgery and reoperated with bilateral neck exploration. However, the PHPT was not cured, until diagnostic CT with contrast had helped localizing a 1 cm ectopic parathyroid adenoma in the right horn of the thymus gland. The adenoma was then removed successfully.

Heterotopic hepatic tissue is a rare development anomaly, exhibiting diverse forms and locations. We present a case report of an asymptomatic woman in her 40s who had an 8 cm mass in the left hypochondrium detected on routine ultrasound, which was initially suspected to be a tumour. Further investigation revealed that the mass had a similar enhancement to the liver on gadoxetate disodium-enhanced MRI and presented a connection with the original liver via vascular pedicle, favouring the diagnosis of accessory liver lobe (ALL). Accurate differentiation of ALL from other abdominal masses poses a diagnostic challenge, potentially leading to misdiagnosis of malignant tumours and unnecessary interventions. Although usually small and asymptomatic, rarely they can present with acute complications, and cross-sectional techniques play an important role in enabling early diagnosis and management. Therefore, radiologists must raise awareness regarding ALL, their imagological findings, and diagnostic pathways, and understand potential associated complications.

The gradually progressive solitary cystic-solid mass of chest CT scans is highly suggestive of lung cancer. We report a case of a 29-year-old woman with a persistent cystic-solid lesion in the right upper lobe. A chest CT scan showed a 35 mm × 44 mm × 51 mm focal cystic-solid mass in the anterior segment of the right upper lobe. The size of lesion had increased over 3 years, especially for the solid component. The right upper lobe pneumonectomy was performed. Postoperative pathological examination showed placental transmogrification of the lung, which is a rare cause of pulmonary cystic lesion.

Ectopic goitre, presenting as an isolated thoracic mass without connection to the main thyroid gland enlargement, is a rare occurrence. We describe a case where a patient reported persistent dry cough and back pain for 1 year, along with throat discomfort unresponsive to medication. A 2×1 cm swelling was noted over the right anterior aspect of the neck. Extensive evaluation, including chest X-rays and contrast-enhanced CT of the thorax, revealed a mediastinal mass suggestive of an ectopic thyroid.This case presents a distinctive scenario involving the simultaneous presence of ectopic mediastinal and cervical thyroid lesions. Both were effectively managed using a minimally invasive approach, combining video-assisted thoracic surgery for the excision of the mediastinal mass and a bilateral axillo-breast approach for the cervical lesion in a single procedure. This approach yielded minimal morbidity, aesthetically pleasing outcomes and rapid recovery. Remarkably, such a case has not been previously documented in the available literature.

Thymoma is a rare malignancy with usual location in the antero-superior mediastinum. Ectopic cervical thymoma (ECT) is an extremely rare tumor that originates from ectopic tissue, and is caused by the aberrant migration of the embryonic thymus. Our patient was a 56-year-old man who had a nodular lesion in the neck for several years. Computed tomography and Enhanced magnetic resonance imaging were performed. He underwent surgery, and a histological examination resulted in a diagnosis of type AB thymoma.

When a neuroendocrine tumor with abundant blood flow is located in the pancreatic tail, it is difficult to distinguish it from accessory spleen. The patient was a 71-year-old woman who was admitted with impaired consciousness and hypoglycemia, raising suspicion of insulinoma. The selective arterial calcium injection test suggested a lesion in the pancreatic tail. Contrast-enhanced computed tomography and magnetic resonance imaging (MRI) showed a mass in the splenic hilum; however, its continuity with the pancreas was unclear. Contrast-enhanced MRI using super paramagnetic iron oxide (SPIO) showed no SPIO uptake in the splenic hilar mass. SPIO contrast-enhanced MRI is considered useful for differentiating pancreatic endocrine tumors from paraspleen tumors.

Transverse testicular ectopia (TTE) is an infrequent ectopic testis where both testes descend via the same inguinal canal, located in the same hemiscrotum, and augments the risk of developing testicular tumours. Type II TTE is accompanied by persistent Müllerian duct syndrome, where the Müllerian structures persist for various reasons. Here, we present a case of an adult in his early 30s, who presented with a right testicular swelling and was diagnosed as type II TTE and testicular mixed germ cell tumour after surgery. We could find only 13 similar cases of TTE and testicular tumours in the literature. Our case highlights the importance of clinical acumen with detailed history, meticulous clinical examination, radiological investigations and a detailed pathological examination while dealing with such sporadic presentations.

To investigate the value of preoperative ultrasound combined with 99mTc-MIBI imaging for the diagnosis of ectopic intrathyroid parathyroid gland (ETPG) in patients with secondary hyperparathyroidism (SHPT). One hundred and eleven patients with SHPT who underwent total parathyroidectomy plus forearm transplantation from January 2015 to January 2022 in the Third Hospital of Hebei Medical University were selected. All patients underwent routine preoperative ultrasonography and 99mTc-MIBI imaging, and with pathological diagnosis as the gold standard, the clinical data of ETPG patients were selected, including clinical manifestations, laboratory tests, preoperative ultrasonography and 99mTc-MIBI imaging for localization and diagnosis, intraoperative exploration and postoperative pathology, and postoperative follow-up. To analyze the ultrasound manifestations of preoperative parathyroid hyperplasia and the results of 99mTc-MIBI imaging in patients with ETPG. Among 111 patients with SHPT, there were 5 patients with ETPG, 1 male and 4 females with a mean age of (45.00â ±â 5.05) years, and 6 ectopic parathyroid glands were located in the thyroid gland. The incidence of ETPG was 4.5% (5/111), 4 were detected by ultrasound, 2 were not detected with a diagnostic accuracy of 66.7% (4/6), 3 were positive for 99mTc-MIBI imaging, 3 were negative with a diagnostic accuracy of 50.0% (3/6). Among them, one was not detected by ultrasound, but was positive for 99mTc-MIBI imaging, 2 with negative 99mTc-MIBI imaging, but all were detected by ultrasound, and one with negative 99mTc-MIBI imaging was detected by ultrasound but misdiagnosed as a thyroid nodule. A total of 5 ETPGs were detected by ultrasound combined with 99mTc-MIBI imaging, with a diagnostic accuracy of 83.3% (5/6). Patients' postoperative serum calcium and serum parathyroid hormone (PTH) levels were normalized or significantly decreased from preoperative levels. Ultrasound combined with 99mTc-MIBI imaging can achieve higher accuracy than either examination alone in the preoperative localization and diagnosis of ETPG in SHPT patients.

A man in his mid-40s presented to the colorectal surgery clinic with complaints of chronic perianal pain for over 20 years. He had episodes of urinary incontinence associated with pain. There were no other symptoms to suspect bowel pathology. On examination, he was found to have a tender mass in the retro-rectal plane without any evidence of rectal mucosal irregularity. He underwent an MRI of the pelvis, which showed a well-defined T2 hyperintense partly cystic lesion in the presacral region abutting the mesorectal fascia and a normal prostate gland. With a suspicion of a tailgut cyst or a duplication cyst, he underwent an excision of the presacral mass. Intraoperatively, there was a 2 × 2 cm well-defined firm, cystic lesion anterior to the fifth sacral vertebra and coccyx. The lesion was adherent to the mesorectum and was excised. On histopathology, there were features of muscular stroma and bilayered glandular epithelium with clear cytoplasm conclusive of a benign ectopic prostate.

A 29-year-old primigravida at 31 weeks of gestation was referred for intrathoracic kidney (ITK). Ultrasound revealed left kidney intrathoracic placement with an anteriorly positioned ectopic adrenal gland. Magnetic resonance imaging confirmed diaphragmatic interruption and colon herniation. A female neonate, delivered at 37 weeks, underwent successful thoracoscopic repair for a left Bochdalek hernia. Despite compression of the left lung, notably optimistic lung-to-head ratio (LHR) values were observed, correlating with favorable outcomes. This case underscores the rare occurrence of ITK, its association with Bochdalek hernia, and the importance of comprehensive prenatal evaluations.

KBG syndrome is a rare genetic disorder caused by heterozygous pathogenic variants in ANKRD11. Affected individuals have developmental delay, short stature, characteristic facial features, and other dysmorphic findings. To date, a spectrum of unspecific neuroradiological defects has been reported in KBG patients, such as cortical defects, white matter abnormalities, corpus callosum, and cerebellar vermis hypoplasia.Deep clinical and neuroradiological phenotyping and genotype of a patient presenting with mild cognitive and behavioral problems were obtained after written informed consent.We herein describe the first KBG patient presenting with cerebellar heterotopia, a heterogeneous malformation characterized by the presence of clusters of neurons within the white matter of cerebellar hemispheres.This novel association broadens the neuroradiological spectrum of KBG syndrome, and further prompts to investigate the potential functions of ANKRD11 in cerebellar development.

Crossed Testicular Ectopia (CTE) or transverse testicular ectopia is an anecdotic urogenital anomaly in which both testes are located on the same side, generally associated with a patent processus vaginalis (PPV). The condition can be detected by ultrasound. Nevertheless, the diagnosis is often missed preoperatively and CTE is recognized intraoperatively. Controversy exists regarding management and the role of diagnostic laparoscopy. The surgical technique depends on the anatomy of vas, vessels and testis found on surgical exploration. Diagnostic laparoscopy can be useful to rule out a vanishing testis and detect Müllerian remnants. We present the case of 8-months infant with no palpable testis on the right side and no signs of inguinal hernia, reporting the management and reviewing the scarce existing literature in this regarding.

Pancreatic heterotopy is a rare entity defined as the presence of abnormally located pancreatic tissue without any anatomical or vascular connection to the normal pancreas. Heterotopic pancreatic tissue can be found in various regions of the digestive system, such as the stomach, duodenum, and upper jejunum, with the less commonly reported location being the gallbladder. Gallbladder pancreatic heterotopia can be either an incidental finding or diagnosed in association with cholecystitis. Pancreatitis of the ectopic tissue has also been described. In this context, we report three cases of heterotopic pancreatic tissue in the gallbladder with different types of pancreatic tissue according to the Heinrich classification. One patient was a 24-year-old male who presented with acute pancreatitis symptoms and an ultrasonographical detected mass in the gallbladder, which proved to be heterotopic pancreatic tissue. The other two cases were female patients aged 24 and 32, respectively, incidentally diagnosed on histopathological examination after cholecystectomy for symptomatic cholelithiasis. Both cases displayed chronic cholecystitis lesions; one of them was also associated with low grade dysplasia of the gallbladder. Although a rare occurrence in general, pancreatic heterotopia should be acknowledged as a possible incidental finding in asymptomatic patients as well as a cause for acute cholecystitis or pancreatitis.
