    A Rare Complication of Umbilical Vein Catheterization: TPNoma: US, X-ray, and MRI Findings

    BACKGROUND: Umbilical vein catheterization (UVC) is an early venous access route in newborns and is frequently used for delivering total parenteral nutrition (TPN) and medications. Vascular, hepatic parenchymal, and infectious complications of UVC can be seen rarely. OBJECTIVE: We present preterm neonates\" X-ray, US, and MRI findings with parenchymal TPN extravasation and portal vein thrombosis. Our case was the first case about MRI findings of TPNoma. CASE PRESENTATION: A 30 week female with a birth weight of 1340 g was born via Cesarean section. Due to the diagnosis of transient tachypnea of the newborn and prematurity, the infant was hospitalized in the neonatal intensive care unit. On the first day of hospitalization, UVC was inserted and TPN with 20% lipid content was started. After 10 days, UVC was removed and TPN treatment was continued with a piccline catheter. Abdominal US and portal venous Doppler examination was applied to the patient whose general condition deteriorated on the 12th day. US and Doppler revealed a lesion of 17x17x18mm in size with lobulated contour, hyperechoic heterogeneous internal structure, and no central or peripheral blood supply was observed in the left lobe of the liver. Moreover, a filling defect compatible with a thrombus was observed in the proximal part of the left portal vein. An abdominal MRI was performed to characterize this liver lesion. Axial T1 weighted and T2- weighted images showed a heterogeneous hyperintense lesion without contrast enhancement. Axial fat saturation T1-weighted and out of phase T1-weighted images showed a reduction in signal intensity. US and MRI examinations showed that the thrombosed umbilical vein ended superior to the lesion. In the differential diagnoses, fat-containing lesions such as lipoma-teratoma and fat-containing collection secondary to extravasation of TPN treatment via UVC were thought. CONCLUSION: In the differential diagnosis of liver localized lesions in newborns, UVC-related liver injury should be considered and the localization of the catheter tip should be checked. In case of the doubt based on US and X-ray findings, presence of fat on MRI could be diagnosed. Serious complications should be avoided with catheter revision or removal.

    Association of trochlear dysplasia with knee meniscal–cartilage damage and anterior cruciate ligament mucoid degeneration
    (2023-01-01) Atay M.; YILMAZ T. F.; Sarı L.; TOPRAK H.; YILMAZ, TEMEL FATİH; SARI, LÜTFULLAH; TOPRAK, HÜSEYİN
    © 2022 The Royal College of RadiologistsAIM: The purpose of this study was to evaluate meniscal and tibiofemoral cartilage injury in patients with trochlear dysplasia (TD) and investigate whether there were correlations between TD grade and meniscal and cartilage injury. In addition, the relationship between TD and mucoid degeneration of the anterior cruciate ligament (ACL-MD) was investigated. MATERİALS AND METHODS: Magnetic resonance imaging (MRI) examinations of 133 patients with TD were included in the study. TD was graded (types A, B, C, D). The tibial tuberosity (TT)–TG distance was also measured. The ACL was assessed for ACL-MD. Both menisci were evaluated for the degeneration and tears. Medial–lateral tibial plateau (MTP–LTP), medial–lateral femoral condyles (MFC–LFC), and trochlear cartilage were examined for focal cartilage defect (FCD). RESULTS: ACL-MD was present in 42 of the patients with TD (31.6%). There was a significant positive relationship between ACL-MD and TT–TG distance. Meniscal tear was detected in 40 (30.1%) of all patients. FCD were detected in the tibiofemoral compartments in 41 (30.8%) of 133 patients. There was a significant positive relationship between the presence of FCD in the LFC and the type of TD (p<0.01). FCD was present in the LFC of all cases in the type D. A significant positive relationship was found between the TT–TG distance and the presence of FCD, especially in the anterior part of LFC (p<0.01). There was a significant relationship between the lateral trochlear cartilage defect and the type of dysplasia (p=0.037). CONCLUSİON: TD is a significant risk factor for ACL-MD, meniscal, and tibiofemoral cartilage injury.

    Advanced cerebrospinal fluid flow MRI findings of aqueductal stenosis caused by web
    (2023-01-01) YILMAZ T. F.; Sari L.; TOPRAK H.; YILMAZ, TEMEL FATİH; TOPRAK, HÜSEYİN
    Background: The aqueductal web (AW) is one of the causes of aqueductus stenosis (AS). Recent advances in Magnetic resonance (MR) imaging have enabled us to better reveal the cerebrospinal fluid (CSF) flow dynamics and aqueductal anatomy. Purpose: The aim of this study is to evaluate the CSF flow dynamics of patients with AW with phase contrast Magnetic resonance imaging (MRI) and compare them with the imaging findings. Materials and Methods: We evaluated 23 patients under 65-year-old age. On constructive interference in steady-state (T2 CISS) images, the width of prepontine cistern (PPC) and the width of Sylvian aqueduct (SA) were measured. Localization and number of webs were evaluated. The existence of flow at the aqueduct and the presence of spontaneous third ventriculostomy (STV) were evaluated on sagittal Sampling Perfection with Application optimized Contrast (SPACE) sequences. Results: Of the 23 patients included in the study, 11 were male and 12 were female. The mean age was 34.02 (0.5–64). A total of 31 AWs were detected in 23 patients. Six of 23 patients (26.1%) had STV and 17 of those not. Four of 23 patients (17.4%) had aqueductal flow on SPACE sequences. The PPC distance was significantly wider in patients with STV (median: 6.7–4.5, interquartile range (IQR): 1.35, p = 0.004). In the cases where artifact secondary to flow is observed in SPACE sequences in aqueduct, the Evan index (EI) was significantly lower (median: 0.2955–0.3900, IQR: 0.03–0.14, p < 0.001). Conclusion: In patients with a low EI, there may be flow in the SA even if there is a web. In patients with a wide PPC distance, it is necessary to consider the presence of STV and evaluate the presence of flow with the SPACE sequences.

    Patellar height: an important parameter in knee MRI associated with tendinopathy, quadriceps fat pad edema (QFPE), anterior cruciate ligament mucoid degeneration (ACL-MD), and lateral cartilage damage
    (2024-01-01) Atay M.; TOPRAK H.; YILMAZ T. F.; Sari L.; Balsak S.; UÇAN V.; Mehdi E.; TOPRAK, HÜSEYİN; YILMAZ, TEMEL FATİH; SARI, LÜTFULLAH; BALSAK, SERDAR; UÇAN, VAHDET
    Background: Some pathologies associated with abnormal patellar height have been reported in the literature. However, its relationship with some pathologies, such as anterior cruciate ligament mucoid degeneration (ACL-MD) and focal cartilage defect, has not been investigated. Purpose: To investigate the relationship between patellar height with patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. Material and Methods: Magnetic resonance imaging of the knees of 261 patients were classified into three groups as normal, patella alta, and patella baja, and evaluated in terms of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and focal cartilage defect. Results: There were 261 patients (140 men, 121 women; age range = 18–60 years; mean age = 30 ± 4.7 years). Of the 261 patients, 181 (69.3%) were normal, 56 (21.4%) were patella alta, and 24 were patella baja (9.1%). Patellar-quadriceps tendinopathy, quadriceps fat pad edema, and ACL-MD rates were significantly higher compared to the normal group (P <0.05). While a moderate positive correlation was found between patellar height shift and patellar-quadriceps tendinopathy and ACL-MD, there was a small correlation between patellar height shift and quadriceps fat pad edema. The rate of focal cartilage defect was significantly higher in the middle part of the lateral femoral condyle and lateral knee joint only in patella alta. Conclusion: The risk of patellar-quadriceps tendinopathy, quadriceps fat pad edema, ACL-MD, and lateral focal cartilage defect is higher in patients with alta-baja. The radiologist should evaluate these pathologies more carefully, especially subtle ones, in patients with abnormal patellar height.
