Evidence of prior autoerotic asphyxia is often difficult to establish due to the decedent's efforts to hide the activity from others. In this case report, we suggest that a healed fracture of the thyroid cartilage is indicative of prior autoerotic asphyxia activity. The decedent was a 45-year-old man who was found unclothed on the floor of his bedroom with a belt ligature around the neck. A second rope ligature was loosely wrapped around the decedent's wrists, scrotum, and penis. A definitive escape mechanism was not identified, but a nearby towel and barbell weight may have comprised a possible escape mechanism. There was no known history of depression or prior autoerotic activity. Autopsy was notable for the presence of a healed fracture of the right superior horn of the thyroid cartilage. Three-dimensional (3D) surface scanning and 3D printing was utilized to preserve the anatomical findings prior to histologic sampling. To our knowledge, this is the first reported use of 3D surface scanning and 3D printing for the purpose of documenting a forensic finding prior to alteration of the anatomical specimen for histologic sampling. Acute fractures of the superior horns of the thyroid cartilage are not infrequently seen in ligature hanging. Therefore, the presence of a healed fracture in the setting of autoerotic asphyxia likely indicates prior activity. Histologic sampling of the laryngeal cartilages to detect occult healed fractures in autoerotic asphyxia may be useful. Three-dimensional scanning and printing may alleviate concerns for specimen alteration due to histology sampling.

BACKGROUND: Cranioplasty is aimed to restore the structure and function of the lost portion of the skull defect. Many materials can be used for cranioplasty, such as the bones of the patient (autograft), the bones of other patients (allograft), bones of animals (xenograft), or synthetic materials such as acrylic or titanium mesh. These materials are quite expensive and sometimes require complex processes. Manual shaping of material for cranioplasty is also quite time-consuming and prone to cause esthetic dissatisfaction. The author will discuss the case of using polylactic acid (PLA) implant with 3-dimensional (3D) printing customization as a cheap and accurate cosmetic solution for cranioplasty procedures. CASE REPORT: We report 2 cases of skull defect underwent cranioplasty. The first case, female, 20-year-old, had a history of severe traumatic brain injury (TBI) and epidural hematoma. She underwent decompression craniotomy on the left frontotemporoparietal region of her skull. The second case, male, 46-year-old, had a history of spontaneous intracerebral hemorrhage due to arteriovenous malformation (AVM). He underwent decompression craniotomy on the right frontotemporoparietal region of her skull. Both the data of computerized tomography (CT) scan were reconstructed to get 3D model of skull defect. Prosthesis was made by 3D printer accordingly using PLA as material. There was no complication reported postoperatively and cosmetic satisfaction was obtained on both cases. CONCLUSION: The use of PLA implant with 3D printing customization was proved to be cost-effective and good cosmetic satisfaction with no complication reported following cranioplasty procedure.

Popliteal artery thrombosis may present as a complication of an osteochondroma located in the vicinity of the knee joint. This is a case report of a 26-year-old man with symptoms of the right lower extremity ischaemia without a previous history of vascular disease or trauma. Plain radiography, magnetic resonance angiography and Doppler ultrasonography documented the presence of an osteochondrous structure of the proximal tibial metaphysis, which displaced and compressed the popliteal artery, causing its occlusion due to intraluminal thrombosis..The patient was operated and histopathological examination confirmed the diagnosis of osteochondroma.

Rotatory Fixation

✓ The authors report on a 31-year-old man with spontaneous craniocervical osseous fusion secondary to cervical dystonia (CD). After an 8-year history of severe CD, the patient developed a fixed rotation of his head to the right. Three-dimensional computerized tomography reconstructions revealed rotation and fixation of the occiput and C-1 relative to C-2, which was similar to that seen in atlantoaxial rotatory fixation. There was abnormal ossification of the odontoid facet joints and ligaments. Additional ossification was observed in the cervical soft tissue bridging the lateral mass of C-1 and the occiput. The patient underwent partial myectomy of the dystonic left sternocleidomastoid muscle and selective posterior ramisectomy of the right posterior neck muscles; postoperatively he experienced relief of his neck pain. In patients with CD refractory to conservative treatment, the appropriate timing of surgical treatment is important.

We report a sequential neuroimaging study in a 48-years-old man with a history of chronic hypertension and lacunar strokes involving the ventral lateral posterior nucleus of the thalamus. The patient developed mild hemiparesis and severe contraversive pushing behavior after an acute hemorrhage affecting the right thalamus. Following standard motor physiotherapy, the pusher behavior completely resolved 3 months after the onset and, at that time, he had a Barthel Index of 85, although mild left hemiparesis was still present. This case report illustrates that pushing behavior itself may be severely incapacitating, may occur with only mild hemiparesis and affected patients may have dramatic functional improvement (Barthel Index 0 to 85) after resolution pushing behavior without recovery of hemiparesis.

Abstract Background: Horseshoe kidney (HSK) have always been a challenge for urologists depending on its particular anatomy. We report a case of renal tumor in a patient with HSK, who underwent tumor resection by retroperitoneal robot-assisted laparoscopic partial nephrectomy. Case Presentations: A 47-year-old man presented to our hospital with a solid renal mass. Computed tomography urography (CTU) showed a 4.3 × 4.4 cm mass in the upper pole of the right kidney. Patients received a retroperitoneal robot-assisted laparoscopic partial nephrectomy on basis of three-dimensional (3D) reconstructions.Conclusion: The present case report highlights the feasibility of robot-assisted laparoscopic partial nephrectomy for horseshoe kidney, and the advantages of preoperative 3D reconstructions.

AbstractFacial flap surgery depends strongly on thorough preoperative planning and precise surgical performance. To increase the dimensional accuracy of transferred facial flaps, the methods of ultrasound and three-dimensional (3D) surface scanning offer great possibilities. This study aimed to compare different methods of measuring distances in the facial region and where they can be used reliably. The study population consisted of 20 volunteers (10 males and 10 females) with a mean age of 26.7 ± 7.2 years and a mean body mass index of 22.6 ± 2.2 kg/m2. Adhesives with a standardized length of 20 mm were measured in various facial regions through ultrasound and 3D surface scans, and the results were compared. Regardless of the facial region, the mean length measured through ultrasound was 18.83 mm, whereas it was 19.89 mm for 3D surface scans, with both p < 0.0001. Thus, the mean difference was 1.17 mm for ultrasound measurements and 0.11 mm for 3D surface scans. Curved facial regions show a great complexity when it comes to measuring distances due to the concavity and convexity of the face. Distance measurements through 3D surface scanning showed more accurate distances than the ultrasound measurement. Especially in “complex” facial regions (e.g., glabella region and labiomental sulcus), the 3D surface scanning showed clear advantages.

We report a case of sudden, unexpected death associated with meningioangiomatosis in a 13-year-old, previously healthy male without a history of seizures, neurologic deficits, or clinical stigmata of neurofibromatosis. There was no family history of neurofibromatosis. The postmortem examination showed a 5-cm mass involving the right posterior frontal and orbital frontal cortex that had microscopic features diagnostic of meningioangiomatosis. Because no other cause of death was found, we postulate that he likely died as a result of a seizure secondary to meningioangiomatosis.

Aortico-left ventricular tunnel is a rare congenital cardiac defect, which bypasses the aortic valve via the paravalvar connection from the aorta to the left ventricle. The authors report the history of a 14-year-old boy with aortico-left ventricular tunnel in whom the aortic orifice arose from the right aortic sinus and was closed by a pericardial patch. The diagnosis was confirmed by combined two-dimensional and real time three-dimensional echocardiogram and magnetic resonance imaging. This is the first case, in which these complex diagnostic imaging methods have been used in the pre- and postoperative management of this defect. Optimally the new transthoratic three-dimensional echocardiography would be needed to define the anatomy and functional consequences of the aortico-left ventricular tunnel and in the postoperative follow-up.
