“…[5–7] Cystic parathyroid adenomas take up 1% to 2% [4] of PHPT cases. Colsa-Gutiérrez et al [8] considered that cystic parathyroid adenomas could be caused by embryological remnants of the 3rd or 4th pharyngeal pouches and preservation of glandular secretion. However, in this case, it is inferred that acute hemorrhage of preexisting ETPA could explain abrupt cystic degeneration and neck mass.…”

Rationale: Cystic parathyroid adenomas are rare and seldom arise in ectopically located glands which may be found within the carotid sheath, mediastinum, thymus, or thyroid grand. They cannot be detected consistently by any imaging methods. Unusual symptoms may bring about certain pitfalls and difficulties for the diagnosis of primary hyperparathyroidism (PHPT) caused by cystic parathyroid adenomas. Until now, there are no specific guidelines on the management of cystic ectopic intrathyroidal parathyroid adenoma (ETPA). Patient concerns: An 82-year-old male musician presented abrupt thyroid enlargement, hoarseness, and trachea compression when he was playing the clarinet. Thyroid and renal function tests were normal. Serum-free calcium and parathyroid hormone (PTH) were in high concentration. Thyroid ultrasonography (US) detected a giant and cystic nodule within right thyroid lobe, which is the very image of cystic nodular goiter. Parathyroid US was negative. The cystic nodule had a decreasing radioactive uptake of Technetium-99m-methoxyisobutylisonitrile ( 99m Tc-MIBI). At patient's request, the invasive fine-needle aspiration (FNA) was not conducted. Diagnoses: The patient was initially diagnosed as cystic nodular goiter and inconclusive PHPT. Interventions: Enucleation of solitary cystic intrathyroidal nodule was conducted. Outcomes: The cystic nodule strongly resembled a nodular goiter grossly, but it was proved cystic ETPA by histopathology. Postoperative follow-ups found that serum-free calcium and PTH decreased sharply into normal range, and hoarseness and trachea displacement were obviously improved. Lessons: The diagnosis of cystic ETPA is easily overlooked for its rarity. Diagnostic pitfalls, including atypical symptoms, inconclusive imaging manifestation, and unidentified gross specimen, are highlighted. They make the diagnosis of PHPT caused by cystic ETPA challenging. Patients would rather choose surgical excision directly than invasive FNA. Acute hemorrhage of the preexisting ETPA may account for the cystic degeneration.

“…the development of such clinical signs and their intensity are more related to the presence of an anomalous spinal fluid circulation pattern that the absolute degree of cerebellar tonsil descent. 7 Papilloedema, occasionally followed by ischemia and eventual visual impairment or loss, is a rare but important manifestation of Chiari I malformation, with a clinical presentation often similar to that of idiopathic intracranial hypertension. The interesting aspect in our case is that our patient presented with a unilateral optic disc findings.…”

“…Arnold Chiari malformation (ACM) was first described by Cleland in 1883 and later described in detail by the same author in 1891 ( 1 ). ACM belongs to a group of congenital conditions characterized by an anatomic defect of the base of the skull, in which the cerebellum and brain stem herniate through the foramen magnum into the cervical spinal canal ( 2 , 3 ).…”

Orofacial clinical features in Arnold Chiari type I malformation: A case series

BackgroundArnold Chiari malformation (ACM) is characterized by an anatomical defect at the base of the skull where the cerebellum and the spinal cord herniate through the foramen magnum into the cervical spinal canal. Among the subtypes of the condition, ACM type I (ACM-I) is particularly outstanding because of the severity of symptoms. This study aimed to analyze the orofacial clinical manifestations of patients with ACM-I, and discuss their demographic distribution and clinical features in light of the literature.Material and MethodsA case series with patients with ACM-I treated between 2012 and 2015 was described. The sample consisted of patients who were referred by the Department of Neurosurgery to the Oral and Maxillofacial Surgery Service of Hospital da Restauração in Brazil for the assessment of facial symptomatology. A questionnaire was applied to evaluate the presence of painful orofacial findings. Data are reported using descriptive statistical methods.ResultsMean patient age was 39.3 years and the sample consisted mostly of male patients. A high prevalence of headache (50%) and pain in the neck (66.7%) and masticatory muscles (50%) was found. Only one patient reported difficulty in performing mandibular movements and two reported jaw clicking sounds. Mean mouth opening was 40.83 mm.ConclusionsACM-I patients may exhibit orofacial symptoms which may mimic temporomandibular joint disorders. This study brings interesting information that could help clinicians and oral and maxillofacial surgeons to understand this uncommon condition and also help with the diagnosis of patients with similar physical characteristics by referring them to a neurosurgeon. Key words:Arnold-Chiari malformation, facial pain, diagnosis, orofacial.
