To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.

Objective: Hypercalcemia associated with the use of sodium-glucose transporter-2 (SGLT-2) inhibitors is very rare. Only 2 cases have been reported in the current literature. In these cases hypercalcemia occurred with the use of SGLT-2 inhibitors taken with thiazides and excessive calcium salts. We present a case of hypercalcemia and primary hyperparathyroidism diagnosed after dapagliflozin treatment. Methods: We describe the medical history, laboratory test results, parathyroid ultrasound, 4-dimensional computed tomography-magnetic resonance imaging, and histopathology findings of the patient. Results: A 49-year-old man with 5-year history of type 2 diabetes mellitus was found to have hypercalcemia with corrected calcium of 11.28 mg/dL (reference range [RR] is 8.8 to 10.6 mg/dL) 6 months after starting dapagliflozin. Previous records showed normocalcemia for many years. Parathyroid hormone level was 70.8 pg/mL (RR is 15 to 65 pg/mL) and 24-hour urinary calcium excretion level was 492 mg/day (RR is 100 to 300 mg/day). On parathyroid ultrasound, a 4 × 9 × 14-mm hypoechoic lesion inferior to the right thyroid lobe was detected. A 15 × 10 × 9-mm oval lesion was observed in the right paratracheal area. A lesion at T1 vertebra level was also seen on 4-dimensional computed tomography-magnetic resonance imaging. The patient underwent lower right parathyroidectomy. Histopathology confirmed the diagnosis of parathyroid adenoma. The patient was asymptomatic 3 months after the operation with a normal corrected calcium level of 9.2 mg/dL. Conclusions: SGLT-2 inhibitors could have unmasked an underlying mild hyperparathyroidism, as they can increase predisposition to hypercalcemia when used with medications causing it. Volume depletion caused by SGLT-2 inhibitors may also contribute to hypercalcemia. For these reasons, calcium levels should be monitored in patients taking SGLT-2 inhibitors.

Abstract Context.—Death from corpora aliena in the larynx is a well-known entity in forensic pathology. The correct diagnosis of this cause of death is difficult without an autopsy, and misdiagnoses by external examination alone are common. Objective.—To determine the postmortem usefulness of modern imaging techniques in the diagnosis of foreign bodies in the larynx, multislice computed tomography, magnetic resonance imaging, and postmortem full-body computed tomography–angiography were performed. Design.—Three decedents with a suspected foreign body in the larynx underwent the 3 different imaging techniques before medicolegal autopsy. Results.—Multislice computed tomography has a high diagnostic value in the noninvasive localization of a foreign body and abnormalities in the larynx. The differentiation between neoplasm or soft foreign bodies (eg, food) is possible, but difficult, by unenhanced multislice computed tomography. By magnetic resonance imaging, the discrimination of the soft tissue structures and soft foreign bodies is much easier. In addition to the postmortem multislice computed tomography, the combination with postmortem angiography will increase the diagnostic value. Conclusions.—Postmortem, cross-sectional imaging methods are highly valuable procedures for the noninvasive detection of corpora aliena in the larynx.

Introdução: O Os sustentaculum é um osso acessório raro localizado na extremidade posterior do sustentaculum tali. A coalizão tarsal pode ser considerada uma anomaliacongênita que pode se tornar sintomática. Frequentemente, é necessária a TC ou a RM para confirmar o diagnóstico de coalizão talo-calcânea quando os achados nas radiografiassão ambíguos. Objetivo: Relatar um caso incomum de Coalizão da articulação talocalcaneana com Os sustentaculum, diagnosticado por exames de imagem. Relatodo Caso: Mulher de 26 anos com “caroço” no tornozelo direito há 10 anos promovendo dor intermitente. Apresenta piora ao usar salto – independentemente do tempo, ao andar ou ao ficar em posição ortostática por mais de 1 hora, referindo dor a palpação e irradiação para o pé. A radiografia do tornozelo direito apresenta ossículo acessório na porção medial da articulação talo-calcânea – Os sustentaculum, confirmada pela tomografia computadorizada. A ressonância magnética diagnostica coalizão talo-calcânea extra-articular com Os  ustentaculum. Conclusão: É importante ressaltar que o Os sustentaculum não é apenasum ossículo acessório ou uma fratura antiga, ele é um componente de um tipo de coalizão talo-calcânea extra-articular, o que faz com que essa condição seja geralmente sintomática. Portanto, se um paciente com Os sustentaculum apresentar sintomas na área articular talo-calcânea medial, uma coalizão talo-calcânea extra-articular com Os sustentaculum deve ser considerada. Palavras-chave: Coalizão tarsal, Tomografia computadorizada por raios X, Imagem por ressonância magnética, Radiografia ABSTRACT Introduction: The Os sustentaculum is a rare accessory bone located at the posterior end of the sustentaculum tali. The tarsal coalition can be considered a congenital anomaly that can become symptomatic. Often, CT or MRI is required to confirm the diagnosis of the talo-calcaneus coalition when the findings on radiographs are ambiguous. Objective: To report an unusual case of a coalition of the talocalcaneal joint with Os sustentaculum, diagnosed by imaging exams. Case Report: A 26-year-old woman with a “lump” in her right ankle for 10 years causing intermittent pain. She worsens when wearing heels - regardless of the time when walking or standing in an orthostatic position for more than 1 hour, referring to pain on palpation and irradiation to the foot. The right ankle radiograph shows an accessory ossicle in the medial portion of the talocalcaneal joint – Os  Sustentaculum, confirmed by computed tomography. Magnetic resonance imaging diagnoses extra-articular talo-calcaneus coalition with Os sustentaculum. Conclusion: It is important to emphasize that the Os sustentaculum is not just an accessory ossicle or an old fracture, it is a component of a type of extra-articular talo-calcaneus coalition, which makes this condition generally symptomatic. Therefore, if a patient with Os sustentaculum shows symptoms in the medial talo-calcaneus joint area, an extra-articular talo-calcaneus  coalition with Os sustentaculum should be considered.

Introduction Paratesticular lesions are common, and one subgroup is paratesticular rhabdomyosarcoma. The latter is a relatively uncommon (but aggressive) tumour that affects children and adolescents predominantly. Ultrasound is the first-line investigation, but can be inconclusive. Magnetic resonance imaging (MRI) can provide useful information, but its role in the diagnosis of rhabdomyosarcoma is not clear. Case History We report a 17-year-old male who presented with a one-month history of a rapidly enlarging, non-tender, lump in the right testicle. Urgent ultrasound of the scrotum revealed a heterogenous paratesticular mass that was hypervascular and showed calcification in the right inguinal area. MRI of the pelvis showed a solid, enhancing lesion of dimension located superior to the upper pole of the right testes and a slightly heterogeneous T2 signal, but was homogenous post-contrast. The patient underwent right radical orchidectomy, and histology results were assessed. He received chemotherapy and is being followed up. Conclusions Improvements in imaging in addition to early surgical intervention and chemotherapy treatment are crucial to improve survival chances against rhabdomyosarcoma. Ultrasound findings for benign diseases may mimic those seen in rhabdomyosarcoma. In such cases of diagnostic uncertainty, our surgical team suggest MRI to reduce the risk of a delayed diagnosis and time to treatment.

Objective Intraocular foreign body (IOFB), a frequent cause of ocular trauma, causes serious damage to the eyes. This study was designed to elaborate and compare the characteristics of different magnetic resonance imaging (MRI) sequences in detecting wooden IOFBs in rabbits. Methods The right vitreous of 24 healthy rabbits was randomly implanted with diverse wooden foreign bodies (diameter φ = 0.2 mm). The T1-weighted imaging (T1WI), T2-weighted imaging (T2WI), proton density-weighted imaging (PDWI), and susceptibility-weighted imaging (SWI) sequences were applied individually 2 weeks after the implantation. Results IOFBs were detected as linear low signals on T1WI, T2WI, PDWI, and SWI (SWI image). The detectable rates of poplar wood with a length of 0.5 mm were 0%, 50%, 0%, and 67% for T1WI, T2WI, PDWI, and SWI, respectively. SWI and T2WI sequences exhibited higher sensitivity than T1WI and PDWI. The detectable rates of the first three SWI sequences (magnitude, phase, and SWI) were all 67%, which was higher than that of the minimum intensity projection sequence (33%). Conclusion MRI is practicable in the diagnosis of wooden IOFBs. SWI and T2WI are optimal for the integrated diagnosis of wooden IOFBs and could be used for diagnosis and immediate treatment.

We describe the novel use of sialendoscopy in a 51-year-old man to identify a large and long-standing foreign body (wood) within the facial soft tissues that had eluded detection on previous imaging and surgical exploration. The identification of this foreign body was elusive on both computed tomography and magnetic resonance imaging, illustrating the limitations of imaging in identifying vegetable matter within soft tissues.
